Paper Title:
The Test Study of Bus Engine Mounting Device Dynamic Behavior in Engine’s Idling Status
  Abstract

To investigate the main vibration source which caused the serious vibration in passenger ride area of one type bus under its engine’s idling status, the effect of isolated vibration and energy transfer characteristics of the engine mounting block are tested and analyzed by modern signal processing technology in this paper. By the measurement of the acceleration response signals of engine’s exciting points and the fixed points of engine’s mounting on its chassis, the transfer function of engine’s mounting block under engine’s idling status was obtained. The calculation and analyzed results draw a conclusion that: the stiffness of the engine’s front mounting is too hard, and the vibration of the engine in idling status was amplified obviously. And then the harshness of the studied bus could be improved according to this conclusion.
