摘　　要：通过混合动力挖掘机与传统挖掘机回转系统的对比,分析回转系统运动特性及各个回转过程,给出回转系统转动惯量,启、制动力矩及回转阻力的计算方法和流程,在此基础上,通过AMEsim软件搭建传统挖掘机液压马达回转系统及混合动力挖掘机电机回转系统的系统模型,并给出液压马达回转系统和电机回转系统的控制策略,通过实例计算和模型仿真得到两种情况下的综合特性曲线,验证了分析过程和模型的正确性,为混合动力挖掘机回转系统的计算分析和仿真提供了一套行之有效的方法。Through comparison of slewing systems used in hybrid power excavator with the traditional excavator we have analyzed motion features and slewing processes of the slewing systems before giving rotation inertia therein,plus computation and the flow for the start torque,brake torque,and slewing resistance,on which basis we set up a systematic models with AMEsim software for hydraulic motor slewing system of the traditional excavator versus the motor slewing system in the mixed power excavator,respectively.We have given also how to control the hydraulic motor slewing system and the motor slewing system.Thru actual sample computation and model simulation we got comprehensive characteristic curves to have proved correctness of the analytic process and the modeling,thus providing a set of feasible method for calculation analysis and simulation of the slewing system in hybrid power excavators.
