摘　　要：基于系统动力学分析软件ADAMS,建立了工作装置虚拟样机模型、模拟典型作业方式,实现了完整的运动学、动力学分析仿真过程,并结合某企业平地机工作装置的设计实例,对各作业方式下的机构运动进行了设计验证.通过进一步的仿真分析获取了各作业方式下工作装置运动学特性以及工作装置部件的动力学性能,并基于有限元分析软件Hy-perworks对工作装置部件进行了强度校核.结果表明,该方法有利于对工作装置的结构设计、机构优化以及结构拓扑优化.A kinematic and dynamic analysis method of working device grader is proposed in terms of complex spatial mechanism.Firstly,spatial mechanism model of this working device was extracted according to its structure,lower-mobility parallel mechanism and simple planar mechanism were confirmed to be the main parts.Virtual prototype model of the working device was set up based on system dynamical analysis software,i.e.ADAMSTM,driving functions were also applied to the cylinders according to the typical actual working conditions,the complete simulation process of kinematics and dynamics was performed consequently.Combined with the example of grader working device in an enterprise,mechanism motion design of all kind of working conditions was verified.Kinematic characteristics of the working device based on kinds of operation modes,together with the dynamic characteristics of components were obtained on the basis of further analysis and simulation,eventually,the strength of the working device component was also checked based on finite element analysis software,i.e.HyperworksTM.Such analysis method would be valuable for the structure design,mechanism optimization and structural topology optimization.
