摘要:: 为了研究轮式装机前车架在典型工况下的受力情况，首先对轮式装载机的工作阻力进行理论计算，利用Pro/E软件建立三维实体模型，再通过MECH/Pro接口将三维实体模型导入ADAMS软件中，建立轮式装载机整车机构的虚拟样机模型，以此为基础对装载机前车架进行动力学仿真分析，获得前车架各铰接点的载荷时间历程，分析前车架在作业工况中的动态特性，为后续有限元分析和疲劳寿命分析奠定研究基础.

Abstract:: For studying the stress state of the front frame of wheel loader in typical working condition,the working resistance of wheel loader was calculated firsty in theory.the three-dimensional solid model of wheel loader mechanism was established in Pro/E software,which was imported into ADAMS software by the MECH/Pro interface.And then the virtual prototype model was established.On this basis,the front frame of the loader for the dynamic simulation analysis was discussed,obtains the each joints loadingtime course of the front frame,analyses the dynamic characteristics of the front frame in working condition,provides the basis for the following analysis of the finite element and fatigue life.
