摘　　要：将虚拟样机技术与ADAMS软件相结合,建立了挖掘装载机WZ30-25的整机参数化模型;介绍了ADAMS中的驱动约束函数,仿真测量了液压挖掘装载机WZ30-25仿真模型的各种技术参数;最后,通过模型预测了挖掘装载机的工作性能。虚拟样机技术的研究范围主要是机械系统运动学和动力学分析,其核心是利用计算机辅助分析技术进行机械系统的运动学和动力学分析。与传统CAD方法相比,它提高了设计速度和设计质量并降低成本。这种基于虚拟样机模型的参数化建模,对于装载机工作装置的设计研究具有普遍的适用性。The model of the whole machine of Backhoe loader WZ30-25 was set up based on the virtual prototype technology and ADAMS software. The paper showed ADAMS motion function and important technical parameters by measurement on simulation model of WZ30-25. The capability of Backhoe loader was forecasted by dynamic simulation in the end. The technical range of research of the virtual prototype technology is mainly the kinetics and dynamics analysis of the mechanical system, its core is to do the kinematics and dynamics of mechanical system analysis. Compared with traditional CAD methods, the speed and quality of design were improved further with less cost. This method which based on the model of virtual prototype has general applicability to the optimal research of loaders＇ working device.
