摘要

Two dynamic models are established to study the torsional vibration and noise characteristics of a power-split hybrid driveline. One is developed using mathematical rotational motion of the driveline components in matrix form. The other dynamic model of the hybrid driveline is built in the multi-body dynamic software ADAMS. The natural frequencies and vibration modes computed from the two methods show a remarkable agreement. Moreover, the noise source identification for the power-split hybrid driveline is also undertaken according to the acoustic measures on the test bench. This study can provide a valuable reference to the development of hybrid electric vehicle in the future.
