摘　　要：针对拉臂车工作装置变负载、多工况的工作特点,利用机械系统动力学仿真分析软件ADAMS建立机械-液压联合仿真模型,为得到更加真实的动力学响应,将箱体滚轮与地面、箱体与副车架导向轮定义为非线性弹簧-阻尼碰撞接触力约束关系。分析结果表明:机械-液压联合仿真能够有效地模拟工作装置在装箱和举升卸料过程中油缸力和拉臂作用力的动态变化规律,从而为拉臂车工作装置动态分析提供了一种有效方法。The hydrostatic-mechanic model of working device of hooklift was established in the environment of mechanical system dynamics software of ADAMS and a co-simulation was carried out under variable loads and multi-operating modes.The contacts between container wheels and the surface,container and directive wheels of subframe were defined as non-linear spring-damping forces,so a more actual dynamic response was obtained.The analysis of the results reveals that the co-simulation can effectively reflect the dynamics of cylinder force and hooklift force under the operations of container-loading and garbage-dumping.A practical method for dynamic analysis of hooklift working device is provided.
