摘　　要：挖掘机工作装置最初的设计是以铲斗挖掘为主要功能,装上冲击器后其工作状况为冲击振动,需要对工作装置进行动态特性分析。采用Pro/E软件对某型号挖掘机式冲击器进行三维建模,然后利用ANSYS Workbench建立有限元模型。对挖掘机式冲击器工作装置的三种工况进行模态分析,得到工作装置的固有频率和振型,为挖掘机和冲击器的功率匹配提供一定的依据,并为其优化设计提供理论基础。Excavator＇s working devices is mainly designed for scooping at first, after installing the impaetor, the working envi- ronment is turning to frequency vibration, and thus analyzing the working device＇s dynamic characteristic is necessary. Pro/E software is used to design the three-dimensional model of excavator-impactor and through ANSYS workbench software, finite element analysis model is built. Then the model analysis of the working device under three working conditions is carried out. The natural frequency of working device and vibration mode are got, which provides the basic theory to match excavator and impactor, and the optimization design.
