2 SMT Software Development Process Slide 2

3 SMT Software Development Process Customer driven Development plan based on input from our users together with assessment of market trends Any requested feature or functionality improvement is given serious consideration Priority for features depends on Demand Market potential Resource availability Required development time Slide 3

4 SMT Software Development Process SMT release philosophy is to release functionality as soon as it is ready to do so As discussed in Gear Technology Nov/Dev 2017 Helping Software Developers Help You This leads to more releases each year but means that customers do not have to wait until an e.g. yearly release to benefit Slide 4

5 MASTA Developments in the Last Year Slide 5

9 MASTA 8.x Slide 9

10 Bearing Database Updates In MASTA 9 an SKF Catalogue update includes parameters previously not provided by SKF including, element diameter, number of elements, PCD and contact angle Slide 10

11 MASTA KIMoS Interface Slide 11

12 Gleason GEMS Interface Latest Gleason bevel gear analysis software Interface with MASTA is the same as for KIMoS Import GEMS xml file Export misalignments from MASTA to GEMS Import TE for NVH analysis Slide 12

13 Electric Machine NVH Harmonic response due to excitation from transmission error and electric machine loads Slide 13

14 Macro Geometry Design Space Search Explore the cylindrical gear macro geometry design space Slide 14

15 Micro Geometry Design Space Search Explore the cylindrical gear micro geometry design space Slide 15

16 Parametric Study Tool The Parametric Study Tool (PST) module is being continually enhanced New features include: Change design properties Log results (instead of saving entire analysis) Save report at each step Save design at each step Run and plot results on duty cycles Full Factorial Design of Experiments Significantly improved use with NVH Slide 16

17 Undo/Redo MASTA now includes significant undo/redo functionality including the following operations: Values in the Properties grid Values in the Input Editors Values in the Shaft Profile editor Adding and deleting components. Slide 17

18 Cloned Gears Create a clone of a gear that has the same properties as the original Simplifies design and optimisation of twin and multi-layshaft designs Slide 18

19 MASTA 9 Slide 19

20 MASTA 9 Targeted for release October/November 2018 At final beta stage features all complete, undergoing final testing Slide 20

21 Acoustics Airborne Sound Power Calculation of airborne sound power in MASTA using ISO/TS 7849 Based on velocity normal to surface Slide 21

22 Acoustics Export Previous workflow MASTA FE/Acoustic Package Dynamic Displacements at Bearings TE Dynamic Response to TE Dynamic Response to Bearing Dynamic Displacements Acoustic Analysis Slide 22

23 Acoustics - Export Export of operating deflection shapes directly to acoustics packages Saves time rerunning frequency response calculation MASTA FE/Acoustic Package Housing Surface Velocities TE Dynamic Response to TE Surface Velocities Acoustic Analysis Slide 23

24 Acoustics Export and MASTA Sound Power Slide 24

25 Shaft Meshing Mesh MASTA shaft geometry Tetrahedral or hexahedral meshes supported Includes details such as fillets and grooves Slide 26

26 Shaft Meshing With PST The shaft meshing functionality can be used in conjunction with the parametric study tool or RUNNA to: Modify shaft profile parameters Run a command to automatically mesh the geometry and set up connections to MASTA model Run a command to automatically perform the stiffness reduction Run e.g. NVH analysis and write dynamic mesh force results Slide 27

27 Bearing Mounting More detailed input available for bearing mounting When including fitting and thermal effects radial mounting type and clearance will be calculated automatically Slide 28

28 Improved CVT Model Initial release includes axial forces/moments on sheaves due to clamping Set ratio on a load case basis Future versions will include Axial movement of sheaves Replace sheaves with FE Slide 29

29 DRIVA LTCA Coupling DRIVA analyses can now couple to the MASTA Basic LTCA calculation Slide 30

30 Flexible Spline Coupling Improved modelling of FE representations of splines. For example, ring gear splined to housing with clearance Old process involves using axial clearance bearings for the contacts. This was time consuming to set up Developments allow easy specification and set up of such models with a dedicated flexible spline model Slide 32

31 Flexible Spline Coupling Slide 33
