基于ADAMS的排土机底盘振动分析与结构改进

摘要

SolidWorks was applied to establish 3D model of the chassis of the dumping spreader,and then the model was imported into ADAMS.ADAMS/Vibration analysis module was used to simulate and analyze the vibration response of the model,so as to obtain the vibration characteristics of the system.Thus the resonance frequency of the system could be avoided,or the resonance frequency of the system was altered by optimizing the system parameters,which was applied to the design of the chassis of the crawler traveling mechanism of PA200-1600 dumping spreader.Finally,the vibration of the dumping spreader reduced,and its reliability and stability improved.%应用SolidWorks建立排土机底盘的三维模型,将模型导入ADAMS中,利用ADAMS/Vibration 振动分析模块对模型进行振动仿真分析,得到系统的振动特性,从而规避系统的共振频率,或者通过修改系统参数改变系统的共振频率,并将此分析应用到PA200-1600型排土机履带行走机构底盘的设计中,最终在减小整机振动方面取得了显著效果,改善了排土机运行的可靠性和稳定性.
