摘　　要：液压挖掘机是一种机电液相结合的复杂工程机械,利用多种仿真工具对其进行耦合分析是至关重要的。基于Pro/E 4.0构建液压挖掘机整机机械模型,利用ADAMS接口功能完成挖掘机虚拟样机模型的构建,进行大量的运动学和动力学仿真分析;推导了斗杆液压缸流量和转角控制传递函数,结合ADAMS/Control和MATLAB/Simulink模块完成斗杆液压缸机—电协同耦合仿真。仿真结果表明,耦合仿真具有一定的理论价值和实践意义,为物理样机的试制和优化提供依据。Hydraulic excavator is a typical and complicated engineering machine by combination of mechanical,control and hydraulic system.It is vital to carry out coupling analysis by use of multiple simulation tools.A hydraulic excavator mechanical model was constructed based on Pro/E 4.0.And hydraulic excavator virtual prototype was finished by use of ADAMS interface function as well as a great deal of kinematics and dynamics simulation analysis was carried on.Thus the flow and angle transfer function of bucket rod hydraulic cylinder was deduced,and mechanical and control simulation for bucket rod hydraulic cylinder was finished coupled with ADAMS/Control and MATLAB/Simulink modules.Simulation results show cou pling simulations have certain theory value and practical significance,which provide evidence for trial and optimization of physical prototype.
