The implementation of sophisticated analysis and simulation software has complemented, but not replaced, traditional forms of testing and validation. All aspects of the transmission and driveline therefore are rigorously examined on dynamic test rigs in the research and development laboratory with the aim of reducing friction, increasing mechanical efficiency, optimising noise vibration and harshness (NVH) performance, while also improving transmission and driveline reliability.
The MTS tensile test machine control system has the latest FlexTest 40 hardware and Multipurpose Elite Testsuite software. This package gives enhanced flexibility in the definition of test profiles, rig control and automated reporting. Sophisticated control methods can be applied to any load test, with the option to apply closed-loop control to external variables from customer sensors as well as via in-built load and displacement parameters. Specific rigs used include:-
- Quasi-Transient differential test rig (QT-DTR)
- Gimbal oil system test rig
- Viscous & hydraulic differential test rig
- Heat rejection test rig
- MTS servo hydraulic test rig
- Loaded steering rack and pinion test rig
- Multiple configurable spin test rigs
- Vehicle configurable gearchange test rig
- Loaded gearbox test facility
- ‘Quiet’ laboratory with NVH accelerometers
- 4-Square gear test rig
We acquire data by extensively using HBM laboratory specification equipment, with portable modules for vehicle based acquisition similarly specified to laboratory standards.
