摘　　要：利用三维实体建模软件Pro/E与机械系统动力学仿真分析软件ADAMS建立了挖掘机器人机械子系统、液压子系统模型,并在ADAMS环境中利用参数关联技术,将两个子系统模型集成,建立起挖掘机液压与机械一体化的虚拟样机模型;在此基础上进行了大量的运动学和动力学仿真。研究结果为预见设计方案的可行性及物理样机的试制提供了一定参考;可提高产品开发速度和精度,降低开发成本;具有重要的理论与工程意义。The mechanical system and hydraulic system of an excavator were built using the software of Pro/E and ADAMS (Automatic Dynamic Analysis of Mechanical Systems). The integration of the two systems established the hydraulic-hydraulic virtual robotic excavator model through parameter correlation technology under ADAMS environment; and a large amount of kinematic and dynamic simulations were carried out. The results offer certain reference for predicting the feasibility of the design plan and trial-production of the physical prototype. The method has important theory and engineering meaning for its improving the speed and precision of product development; and reducing the development cost.
