摘　　要：以某型挖掘机为研究对象,利用Solidworks建立三维模型并完成装配,导入ADAMS中,通过添加约束条件建立虚拟样机系统。基于ADAMS进行仿真分析,获得动臂主要铰接点处的载荷受力曲线,提出将三维模型简化为二维,再通过平面坐标系受力分析的方法得出动臂铰链处的受力理论值,并与仿真计算得到的数据进行对比,验证仿真结果的准确性,为液压挖掘机进行有限元分析提供可靠的载荷谱,从而可以更加准确地对挖掘机进行结构设计和优化。Taking a certain type of excavator as the research object, based on the solidworks to set up the three-dimensional model and assemble it, then put it into the ADAMS, by adding a constraint condition to establish the virtual prototype system. Based on the ADAMS simulation analysis to obtain main force curve of the movable arm link joint. Put forward to simplify the 3d model to 2d, and to achieve the theoretical value of the stress of movable arm link joint. And then compared with data obtained from the simulation calculation to verify the accuracy of the simulation results. To provide reliable load spectrum for hydraulic excavators finite element analysis. In order to be more accurate for structural design and optimization of the excavator.
