摘　　要：利用AMESim软件进行挖掘机工作装置参数化建模及仿真分析,首先阐述工作装置关键参数的选取原则及获取方法,基于全局变量法建立工作装置模型,然后搭建伺服位置控制模型,实现工作装置性能参数获取和轨迹分析,最后通过挖掘载荷模型获取实际作业工况下工作装置关键铰接点应力,为工作装置强度的计算提供参数。Parametric modeling and simulation analysis of excavator attachment are carried out by using AMESim software.Firstly,selection principle and acquisition method of key parameters of attachment are expounded,attachment model is established based on global variable method,then servo position control model is established to realize performance parameters acquisition and trajectory analysis of attachment,and finally stress of key hinge points of attachment under actual working conditions is obtained through excavation load model,which provides parameters for calculation of strength of attachment.
