摘　　要：随着摩托车向高速、大功率发展,发动机引起的振动已经成为影响摩托车性能的主要因素之一。针对某公司200ml排量摩托车设计开发过程中出现的振动现象,在摩托车发动机与车架之间增加弹性悬挂装置,使悬挂系统的固有频率避开发动机的常用激振频率,对悬挂系统进行仿真分析,合理匹配其性能参数,改善系统的隔振性能,解决整车振动问题,从而提高摩托车的乘坐舒适性。With the development of high-speed and high-power, the motorcycle vibration from engine become one of the major factors affecting the performances of motorcycle. Elastic suspension structure is adopted between the engine and frame for the vibration during the process of designing a certain type of motorcycle with 200 cc engine in some enterprise.Through optimization of the suspension system performance parameters, inherent frequency of suspension system keeping away from the activated frequency of engine in common use is essential. Isolation performance is improved and the vibration is solved. As a result, the comfort is improved.
