Design of test rig

Abstract [en]

Wet clutch are widely used in various components of modern cars, such as automatic transmissions and differentials. Tribological properties play a crucial role in the performance of such clutch. A negative gradient of the ยต-v curve imposes a higher risk for vibrations. There are also others factors affecting clutch performance. An experimental approach is important in investigating wet clutch tribology, since modern computer tools are not yet able to simulate tribochemistry in the contact. An advanced test rig is presented for the study and development of clutches and their behaviour. Friction-speed characteristics can be monitored in the test rig. It is also possible to change the damping and stiffness of the system. Thermal conditions can be investigated both in the rotary and stationary parts. The test rig has been designed in such way that the RC-measuring system is possible to use. An initial study of the prospects of the RC-system has been performed with some results from this investigation given in this paper.
