4 LMS Test.Lab Environmental High-speed, multi-channel vibration control and data reduction systems LMS Test.Lab Environmental provides a powerful, high-speed multi-channel vibration control system, certified for spacecraft testing. The vibration control systems can be expanded to hundreds of control, measurement and limiting channels. Users will find it easy to use for routine random, shock, sine, and combined modes testing and have everything they need for stateof-the-art control and extensive data analysis. Environmental testing for aerospace LMS Test.Lab Environmental delivers a complete solution for qualification and acceptance testing on large and fragile structures such as spacecrafts, satellites, and system prototypes. It is designed for parallel acquisition and online reduction of vibration channels during random or sine closed-loop vibration control testing, in reverberant rooms, or for high frequency transient capture in deployment testing. LMS Test.Lab Environmental consists of two product lines: LMS Test.Lab Environmental Control and LMS Test.Lab Environmental Data Reduction. LMS Test.Lab Environmental Control conducts qualification tests on structures in closed loop, and LMS Test.Lab Environmental Data Reduction is dedicated to design validation by complementing the vibration control system with additional measurement channels, decoupled from the closed-loop control system. Both product lines optimize and increase qualification and acceptance test productivity. The same LMS hardware and software environment can also be used to conduct modal survey tests (MST) in order to correlate and update FE models. Safety is the primary objective LMS Test.Lab Environmental protects the integrity of the tested structure throughout the entire procedure. Real-time control is maintained as the channel count increases. Many safety features are built into the hardware and software to ensure a reliable control loop: from comprehensive pre-test checks, response limiting and notching on any number of channels, to a controlled shutdown if limits are exceeded. Productivity and convenience As the solution is designed for maximum productivity, users can arbitrarily map physical inputs to define control, measurement and monitoring channels; recall calibration values from a database; monitor what they want as the test proceeds and batch plot results with a single click. After each test, real-time animation on a geometry, based on measured data, provides a quick test execution check. Full test object protection The entire measurement chain is continuously monitored during testing for open or short circuits. Overload checks are carried out in several places of the signal paths, including up-front, full bandwidth checks on anti-alias filters. Dedicated hardware circuits guarantee smooth shutdown of output signals, even in case of power failure. During closed-loop control RMS and line-by-line abort checking, the system performs single or multi-point control, drive limitation, sigma clipping, as well as continuous open channel and overload checks. Fast loop times ensure a reliable control loop. Safe, fast and accurate control LMS Test.Lab Environmental supports random, swept sine, tracked sine dwell, shock, waveform replay and combined test The LMS Test.Lab Environmental software is designed to work with the LMS SCADAS III controller hardware system that incorporates 24-bit ADC and DAC technology. This tight integration guarantees maximum safety. Test expensive, unique objects in full safety and confi dence Increase productivity using the convenient and easy workfl ow Test according to a large variety of scenarios, including MIL-STD 810 Keep control over measurements and independently perform parallel measurements in the control loop Validate prototypes in support of design and development 4 LMS Test.Lab Environmental

5 modes for single-input control. It integrates all common industry standards for vibration and shock testing. Highly flexible, the system supports non-standard test specifications and offers an accurate reproduction of target reference spectra on a shaker. LMS Test.Lab Triax MIMO Random Control provides multiple input random control on decoupled shaker setups. Predefined workflow for optimal productivity Smart test routines and the intuitive user interface of LMS Test.Lab Environmental deliver optimal productivity throughout the testing cycle. Operators follow a workflow defined by the supervisor, which includes overall guidelines, predefined transducer sets, online processing and reporting, as well as a set reference profile and control strategy. Users are in control at all times; they can measure as many parallel channels as needed to monitor the structure at all sensitive points. Setup procedures use a spreadsheet-like interface to facilitate the entry of repetitive values. High performance closed loop control The most distinctive feature of the new system is its speed real-time control is maintained for up to a 100 channels at a control bandwidth of up to 20kHz. All LMS SCADAS III signal conditioning modules are supported, so control is possible from accelerometers. Channel mapping gives users the flexibility to use front-ends more efficiently and choose which channels to use for control and measurement. Online data reduction For those cases in which testing requires even more channels, the vibration control system can be extended with an online reduction system using the same measurement algorithms as the vibrationonly system, but on an acquisition-only system. The overall measurement capacity is extended even further. Flexible analysis and effective communication LMS Test.Lab Environmental offers analysis tools for the most demanding test campaigns. With intuitive data navigation, a user attribute-based search functionality, and comprehensive analysis functions, users can easily visualize and interpret test data. The solution automatically generates reports with a single mouse click. Full compatibility with Microsoft Office and embedded support of OLE/ActiveX technologies turns static reports into dynamic information files. Readers can adapt axis scaling, add cursors and change legends to create their own customized view. LMS Test.Lab Environmental helps testing teams effectively visualize, analyze, report, and share their work with others. LMS Test.Lab Environmental 5

6 LMS Test.Lab MIL-STD Testing LMS Test.Lab MIL-STD Testing provides a complete solution for military standards (MIL-STD, GAM-EG.13) qualifi cation testing on structures, using a shaker installation in a closed loop fashion. The solution supports swept sine, random, shock, SRS, combined modes and time replay-based qualifi cation. In every qualifi cation test phase and control mode, the system offers a wealth of safety precautions to protect the test article and test area. Test result documentation is key. A fully automatic logging mechanism makes reporting easy and complete. Automatic setup and test data archiving, transducer annotation on stored spectra, visually appealing formatting of run event log fi les and digital picture support are some examples. All information is available in a very intuitive browser tree so that a fi rst draft can be drawn up by anyone. The LMS Test.Lab Random, Sine, Shock and Single Axis Waveform Replication Control applications support safe, accurate and productive component qualifi cation testing. All applications have been designed with long duration, multiple-operator shift testing in mind. Safe qualification testing for the toughest requirements: MIL-STD The modularly organized solution helps users mix and match sweeping and fi xed sine tones and narrowband in all possible ways so they can set up the most demanding combined modes tests imaginable. For SRS testing, LMS Test.Lab Shock Response Synthesis supports damped sine or wavelet use to create a target time history that complies with the target SRS. A fully automated process provides a default waveform. If the waveform violates shaker limits, individual parameters can be modifi ed in a fully interactive optimization process. A multi-level undo/re-do buffer helps users evaluate different parameter changes, while viewing the resulting waveform, refreshed with every alteration. Each updated waveform is checked against shaker performance limits. This means that tests with higher SRS levels can be run on the existing installation. For precise replication of operational loads, LMS Test.Lab Single Axis Waveform Replication provides measured signal replay directly on the shaker. It extends current testing techniques from classical sine, tracked sine, random and shock control to longduration time waveform replication. Well-organized sheet for test progress monitoring, combining general test status information views with online graphics. To support the test tailoring approach as described in LMS Test.Lab MIL-STD, LMS Test.Lab Mission Synthesis defi nes test specifi cations for single axis random and swept sine vibration testing from measured load data. Resulting test specifi cations are equal in damage and are accelerated because of faster run times. Multiple acceleration loading environments are analyzed for fatigue potential by calculating MRS (maximum response spectrum) and FDS (fatigue damage spectrum). Features Swept sine control Random control Shock control (classical pulse, measured pulse and shock response analysis) Single axis waveform replication Shock response synthesis Combined modes Mission synthesis (optional) Benefits Adapted for military standard testing Complete and flexible combined modes implementation World-class SRS implementation on your shaker installation Full flexibility in sine on random setup, fixed and sweeping sine tones with individual burst schedule.

10 LMS Test.Lab Environmental Control options LMS Test.Lab Sine Notching and LMS Test.Lab Random Response Limiting LMS Test.Lab Sine Notching and LMS Test.Lab Random Response Limiting help users effectively protect test items against over-testing. While the average control signal level matches its reference spectrum, the test object response at particular points may greatly differ, due to resonances during the testing phase. The vibration level at any channel (control or measurement) is limited by an auxiliary reference profile for maximum protection of the test item. Combined modes The LMS Test.Lab Sine on Random (SoR) module offers the possibility to define a background noise level combined with up to ten fixed and sweeping sine tones. The LMS Test.Lab Random on Random (RoR) option offers the possibility to define a background noise level combined with an unlimited number of fixed and sweeping narrow-band signals. Both options in combination with LMS Test.Lab Random Control provide complex profile definition, typically called Sine on Random on Random (SoRoR). LMS Test.Lab Shock Response Synthesis LMS Test.Lab Shock Response Synthesis synthesizes a time waveform that corresponds to a user-defined shock response using a series of superimposed wavelets, a series of superimposed damped sine or a chirp sine. The synthesis module is seamlessly integrated into the shock control application. LMS Test.Lab Mission Synthesis LMS Test.Lab Mission Synthesis helps define test specifications for single axis random and swept sine vibration testing from measured load data. Resulting test specifications are equal in damage and are accelerated for faster run times. Test tailoring methods as described in industry standards such as GAM EG-13, MIL-STD 810F and NATO AECTP 200 are used for this purpose. Multiple acceleration loading environments (defined in either time or frequency domain) are analyzed for fatigue potential by calculating MRS (maximum response spectrum) and FDS (fatigue damage spectrum). LMS Test.Lab MIMO Triax Random Control 3x3 configuration LMS Test.Lab MIMO Triax Random Control is capable of running up to 3 DACs and an unlimited number of measurement channels simultaneously for MIMO closed-loop random control. It includes all necessary features to define and control a random excitation that matches a predefined PSD profile on different measurements points using multiple shakers. Phase control, cross-coupling compensation and adaptive control are based on the Smallwood algorithm for decoupled XYZ MIMO shaker table setups. 10 LMS Test.Lab Environmental

11 LMS Test.Lab Test Sequencing LMS Test.Lab Test Sequencing defines and executes a series of closed-loop vibration control tests. For a smooth and unattended batch execution, the application supports mixing all test modes (swept sine, random and shock), do-loops, pause commands and a variety of SelfCheck options. In addition, it is possible to automatically run the MS Windows program as part of the schedule. This can be used to control other equipment in the lab, synchronize vibration testing with functional or climatic testing, or keep the operator up-to-date on the progress of the test sequence by . LMS Test.Lab Tracked Sine Dwell and LMS Test.Lab Time Recording during Sine and Tracked Sine Dwell Control The LMS Test.Lab Tracked Sine Dwell module excites the structure at a fixed frequency, or at a resonance frequency with frequency tracking. Abort criteria in both control and response levels and frequency range abort in case of tracking dwell are foreseen. Arbitrary sequences of dwell frequencies can be easily defined using the resonance identification tool. LMS Test.Lab Time Recording during Sine and Tracked Sine Dwell Control acquires fixed sampled gapless time data in parallel with a sine or tracked sine dwell control test. The user can select the sample rate for this parallel recording by specifying the desired amount of over-sampling with respect to the maximum sweep frequency. The recorded time data can be further processed using all postprocessing products that support this format. LMS Test.Lab Single Axis Waveform Replication LMS Test.Lab Single Axis Waveform Replication gets field data to the shaker in fewer steps and extends current testing techniques from classical sine, tracked sine, random and shock control to long-duration time waveform replication. The easy-to-use, native MS Windows software requires little training and helps operators automate very long duration tests with full security. The workflow-based user interface of LMS Test.Lab assists the user throughout the complete test. LMS Test.Lab Off-line Sine Reduction LMS Test.Lab Off-line Sine Reduction analyzes the response of a structure at different points to a controlled sine excitation. Throughput data are streamed to disc during the online sine reduction application and can be re-analyzed off-line. A COLA (consistant output level adaptor) channel is required to accurately determine sine excitation frequency. LMS Test.Lab Environmental Analysis options Dedicated noise and vibration analysis add-ins are easily activated and become an integral part of LMS Test.Lab Environmental extending the system for MST (modal survey tests) applications. 3D visualization of measurement results for structural analysis (operational deflection shapes, time animation) or access to any other LMS Test.Lab analysis module is only one click away. This eliminates tedious data exports to more advanced analysis applications, such as LMS Test.Lab Geometry and LMS Test.Lab Operational Deflection Shape and Time Animation, LMS Test.Lab Modal Analysis and LMS Test.Lab Operational Modal Analysis, LMS Test.Lab Run Data Averaging and Comparison Organizer.
