摘要

汽车变速箱作为一个整体,在激振力的作用下产生振动与噪声是必然的结果,轴承、轴系、箱体等对变速箱的振动噪声都有影响。通过模拟运行方式,采集并分析了某型号汽车变速箱的时频域信号。对变速箱进行振动噪声时频域分析,可以掌握振动与噪声特性,这为后续对变速器进行以减振降噪为目的的结构动力学优化设计奠定了试验的基础。

Abstract

As a whole,the automobile transmission producing vibration and noise is an inevitable result under the action of exciting force,the bearing,shaft and box has influence on the vibration and noise of the gearbox. The time- frequency domain signal of a certain type of automobile transmission is collected and analyzed by means of simulation operation mode. Through the time- frequency domain analysis of vibration noise of automobile transmission,the vibration and noise characteristics can be controlled,a solid foundation for the follow- up of structural dynamics optimization design with the purpose of reducing vibration and noise is laid.
