Comparative study on non-traditional torsional vibration isolators for automotive clutch dampers

In this study, the torque transmissibility of non-traditional passive torsional vibration isolators used for automotive clutch dampers were investigated both theoretically and experimentally. The vibration isolation performance of two types of non-traditional passive torsional vibration isolators, an anti-resonant vibration isolator and a centrifugal pendulum vibration absorber, were compared with that of a conventional coil spring damper. The torque transmissibility of each torsional vibration isolator was experimentally measured by using a low-inertia dynamometer incorporating non-contact torque sensing technology and then compared with the simulation results. This study provides fundamental knowledge for designing passive torsional vibration isolators that can suppress the torsional vibration induced by an internal combustion engine.
