汽车发动机弹性支承隔振的解耦方法

Vibration Isolation and Decoupling Technique of Engine - Mount on Vehicles

优化发动机弹性支承参数,对发动机—悬置系统的解耦要求是通常必须满足的条件之一。本文根据传递函数分析振动的方法,探讨了发动机振动模型简化的理论基础、隔振和解耦的关系,以及更适用于计算机寻优的解耦新方法。

By the method of transfer functions, this paper presents the theoretical basis of a simplified model of engine vibratiom. The relationship between vibration isolation and decoupling is also discussed. Finally, a new decoupling method suitable for computer optimization is proposed.
