摘　　要：针对目前世界上最大的800MN模锻压机安装过程中的辅助工装桁架,进行钢结构设计计算与有限元分析研究。首先运用三维设计软件Solidworks,设计建立桁架的三维实体模型,然后根据模型结构和几何参数在ANSYS中建立简化的有限元分析模型,对桁架工作过程中的最不利工况进行载荷分析,并运用ANSYS软件对其进行有限元强度、刚度以及稳定性分析,进而得出最不利工况的应力云图、位移云图以及位移-载荷曲线。分析结果表明:工装桁架最大应力和最大挠度均分别小于许用应力和许用挠度,工作稳定安全系数远大于许用稳定安全系数;模锻压机的成功安装,证明了桁架设计的合理性、安全性和可靠性。Aimed at the auxiliary tooling truss for installation of 800 MN forging press, which is the largest in the world, steel structure design calculation and finite element analysis research were conducted. Firstly, a 3D solid model of tooling truss was designed and built using the Solidworks software. Secondly, according to the model structure and geometrical parameters, a sire plified model for finite element analysis was built with ANSYS. Then, the stress, displacement contour diagrams and displacement-load curves were obtained by analyzing the load, with strength, stiffness and stability considered during the most dangerous working conditions. The results show that the maximum stress and the maximum deflection of tooling truss are respectively less than the allowable stress and allowable deflection. The safety coefficient of working stabili ty is far more than the safety coefficient of allowable stability. Finally, the rationality, safety and reliability of the design of tooling truss are further verified by the success of the forging press installation. 18 figs, 10 refs.
