中置客车发动机悬置系统试验研究

Experimental Research of Suspended System of the Bus with Under Floor Engine

中置客车发动机悬置系统匹配直接影响整车的舒适性,针对中置客车原悬置存在的不足进行了改进设计,通过试验验证改进后的悬置,满足发动机厂家对悬置系统振动传递率的要求,具有较好的隔振效果。

The match of the suspended system of the engine exerted a direct influence upon the comfort of the bus with under floor engine. In view of the inadequacy of original suspension system of the bus with under floor engine, the improvements had been made. The improved suspended system satisfied the needs of vibration transmission rate and had good isolation effects.
