摘　　要：基于多体动力学软件RecurDyn,建立某大型矿用挖掘机履带行走装置动力学模型,对挖掘机平路直行、坡道行驶、原地转向和50m半径转向4种典型工况进行仿真分析,得到4种工况下的履带的驱动转矩和驱动功率,并与实际选用电机的功率值进行对比。分析结果表明基于RecurDyn的动力学仿真可以为履带行走装置的设计提供参考。It is based on a multi-body kinetic software to build up a kinetic model for tracktype travel mechanism of a giant mining excavator,before simulate analyses of flat surface travel,slope travel,track counter turn,and 50 m radius steer as 4 typical operations to have got drive torque and drive power rate at the track,while comparing them with power rate of electric motors actually selected and used.The analysis results show that the kinetic simulation as based on RecurDyn can be a reference provided for track travel mechanism designs to come.
