汽车传动轴弯曲振动分析

商用车传动轴是商用车传动系统中的重要部件,因其振动频率低、刚度小,加上万向节附加力矩,使得传动轴的弯曲振动问题成为影响商用车振动和噪声的重要方面。本文对某商用车传动轴的弯曲振动问题进行了动力学仿真分析,对传动系统的隔振性能进行了分析,总结出中间支撑的刚度对整个转动系的隔振性能的影响规律,对于今后设计具有一定借鉴作用。

Study of the Bending Vibration of Multi-Purpose Vehicles' Transmission Shaft

Multi-Purpose Vehicles' transmission shaft is the important part of Multi-Purpose Vehicles' transmission system.Because of the low liberation frequency,small rigid degree and append bending moment of gimbals.The bending vibration of transmission shaft becomes one of the most important facets which affect the vibration and noises of Multi-Purpose Vehicles.Research is done to the bending vibration of commercial vehicle.The dynamics simulation of both multi-rigid body and multi-flexible body is done,and the ru...
