摘要
运用实验模态的分析方法，对JS2815农用车的发动机-车架系统、车架子结构的动态特性进行了研究。通过识别系统、子结构的模态参数，分析了引起系统振动的因素。进而运用动态修改讨论了悬置特性对系统特性的影响。
The paper studies the dynamic characteristics of engine-frame system and frame structure of a farm truck by using the technique of experimental modal analysis. The factor affecting the system vibration are analysed through obtaining the modal parameters. Moreover, the engine-mounting's effect on system vibration is discussed by means of dynamic modifing program.
