摘　　要：利用APDL参数化设计语言,建立了某剪叉式升降工作平台的参数化有限元模型,进行静载应力试验并与模拟值进行对比,最大误差为13%,在工程应用许可范围内,验证了整机模拟的正确性。对两种危险工况下的整机结构进行了静力强度、刚度有限元分析,得出剪叉臂体的薄弱部位,为下一步改进设计提供了依据。Using the APDL parametric design language,the parametric finite element model of the scissor lift work platform is established.To validate the numerical analysis accuracy,the static load stress experiment is carried out and compared with the simulation results,the relative error is less than 13%,whichcan meet the engineering needs.Two dangerous loading conditions have been chosen to carry out the structural analysis,obtaining the weak part of the scissor body to provide reference and basis for the further improvement.
