10 ANSYS in Transportation Design of rail couplers to meet safety and regulatory requirements with ANSYS Mechanical to model the complex contact behavior between the casing and absorption elements as well as the contact between the rubber elements. The Scharfenberg coupler is one of the most important and successful coupling systems for rail travel. Voith Turbo Scharfenberg keep its leading position in the industry through intensive development and continuous enhancement of his systems. ANSYS technology helps give us the ability to keep high quality standards while streamlining our development process to underline our market leadership in safe and reliable railcar couplers. 10 Eckart Jäde Voith Turbo Scharfenberg

11 Vibration analysis: an application 11

12 ANSYS in Consumer Goods Quickly develop a precision date-change mechanism for an exclusive watch. The simulation results showed outstanding agreement with test results Software from ANSYS provided the accuracy required to design a watch to our exacting specifications. This reduced the need for costly prototypes and helped Audemars Piguet to reduce development time by half. 12 Simulation at Audemars Piguet is supported by ANSYS channel partner CADFEM GmbH.

18 A highly productive solution for structural mechanics 18

19 From the engineer s intent to results: 6 steps to a successful simulation with ANSYS tools 19

20 Step 0: defining the simulation process 20

21 Step 1: geometry and material definitions 21

22 Import geometry from your CAD system, including dimensions 22

23 Defeature models to remove unnecessary details 23

24 A large variety of nonlinear material models 24

25 Layered composites models can be defined through an efficient process mimicking the manufacturing process 25

26 Step 2: defining connections between bodies 26

27 Automatically setup contact between bodies 409 Parts 967 Contact Pairs 27

28 Use joints for mechanisms 28

29 Step 3: Meshing the model 29

30 Robust and automated meshing saves user s time 30

31 Numerous controls are available to locally modify the mesh 31

32 Complex models can be easily meshed 32

33 Automated mesh refinement will ensure the quality of the solution 33

34 Step 4: defining loads and boundary conditions 34

35 A wide variety of loads and boundary conditions are available 35

36 Users can also easily import external data as text files to be used as loads or boundary conditions 36

37 Step 5: understanding and verifying the results 37

38 Thoroughly investigate your results 38

39 Use additional tools to go beyond the standard results 39

40 Automatically generate a detailed simulation report 40

41 Cummins takes advantage of Workbench 41

42 Piaggio: predictability and productivity 42

43 43

44 Going beyond single point solutions to answer the what if questions is straightforward 44

45 Check the box to create parameters! 45

46 All parameters from all types, all physics are managed at the project level. 46

47 Design points will automate the analysis of a number of discrete scenarios 47

48 Response surface will help understand the variations of performance with respect to input parameters over continuous variation ranges 48

49 Sensitivity charts will help you identify critical design parameters and how they influence the performance 49

50 Optimizing from response surfaces is fast and exhaustive. 50

51 Optimizing a product is about finding the right trade-offs Trade-off plot: what performance can be achieved? Interactive optimization 51

52 ThyssenKrupp Airport Systems Using ANSYS DesignModeler, the engineering team reproduced stiffness and other behaviors of a very complicated component, defining many load cases and taking nonlinear simulation into account (material and contacts). Many iterations were completed rapidly because of the interaction between DesignModeler and structural mechanics software, which led to optimizing component cost reducing time to market. The bridge is currently in use. 52
