ABSTRACT – In this study, the torque transmissibility of non-traditional passive torsional vibration isolators used for automotive clutch dampers was investigated and compared by using a low-inertia dynamometer incorporating non-contact torque sensing technology. Based on a conventional coil spring dampers, three types of new torsional isolators are considered in this study; a twin mass damper, an anti-resonance damper, and a centrifugal pendulum absorber. This study provides a fundamental knowledge for designing passive torsional vibration isolators that can suppress the torsional vibration induced by an internal combustion engine.
