Abstract: It is already well known how MT equipped driveline torsional modes are distributed and influenced, and that is successfully applied to MT equipped vehicle noise vibration harshness (NVH) problem solving. However, it is still marginal for systematically continuous variable transmission (CVT) equipped driveline torsional modes sensitivity analysis, hence it is very meaningful to dig out the CVT driveline torsional vibration mode distribution and sensitivity to driveline component inertia/torsional stiffness, hence the right driveline component parameters could be pre-defined from the very start of driveline development or tuned during the refine stage. The aim of this paper is to find out CVT equipped driveline torsional vibration mode sensitivity to driveline component inertia/torsional stiffness and rules to tune the driveline torsional vibration modes to mitigate torsional vibration induced NVH issues.

Keywords: driveline; torsional vibration; CVT; continuous variable transmission; inertia; torsional stiffness; sensibility study; NVH; noise vibration harshness.
