摘　　要：为了保证产品在水平移动过程中高度保持不变,开展了变幅机构优化设计方法的研究。为了掌握门座式起重机整体结构在工作过程中可能出现的危险位置,在CREO软件中构建了简化的门座式起重机的三维模型,利用ANSYS软件对其进行了装配约束条件下的整体结构的有限元分析,得到了最大变形和最大应力的数值及出现的位置,结果表明门座式起重机的刚度和强度满足要求,为相似结构的优化设计和仿真提供参考。To ensure that the height of the product keeps unchanged in the process for horizontal movement,the optimum design method for the luffing mechanism is studied.To find out the dangerous position occuring in the working process of the portal crane.The simplified three-dimensional model of the portal crane is established in CREO software.Then,ANSYS software is used to carry out the finite element analysis of the whole structure based on assembly restriction.The values and positions of maximum deformation and maximum stress are obtained.The results show that the stiffness and strength of the portal crane meet the requirements.In addition,the research in this paper provides a reference for the optimization design and simulation of similar structures.
