摘　　要：该文针对变电站检修工作环境设计一款液压驱动的剪叉升降平台,该平台为对称结构,工作平台为U型结构,可同时容纳2人进行检修工作。为通过虚拟样机技术对该升降平台进行结构分析与优化,首先在SolidWorks中建立该升降平台3D模型,并将其转化为Parasolid文件导入多体动力学仿真软件RecurDyn中,在RecurDyn中建立该升降平台动力学模型,进行动力学仿真求解,通过后处理分析获得液压缸推力曲线、剪叉臂及其连接轴受力状况,为后续结构优化提供参考。Aiming at the working environment of substation maintenance,this paper designs a hydraulically driven scissors lifting platform.The platform has a symmetrical structure and a U-shaped structure,thereby can accommodate 2 people to carry out maintenance work at the same time.In order to analyze and optimize the structure of the lifting platform through virtual prototyping technology,firstly,the 3D model of the lifting platform is established in SolidWorks,and then transformed into Parasolid file into the multi-body dynamics simulation software RecurDyn.The dynamic model of the lifting platform is established in RecurDyn,and the dynamic simulation solution is carried out.The thrust curve of the hydraulic cylinder,the force status of the scissors arm and its connecting shaft are obtained through post-processing analysis,which provides a reference for the subsequent structural optimization.
