摘　　要：以现有的某门型轴类零件压力校直机为基础,对门型校直机的机身进行了优化。首先利用SolidWorks建立了自动校直机的三维模型,再利用ANSYS Workbench对模型在极限工况下进行静力学仿真分析,以验证机体是否满足工况要求。仿真结果显示,机身强度满足要求,但刚度不足。为此对机身的厚度和结构进行了合理的改进,并使其满足轻量化设计的要求。对改进后的结构进行了仿真分析,并将优化后的结果和之前结果进行对比,分析结果表明结构改进后的机身重量降低且强度和刚度均满足要求。Based on the existing pressure straightening machine of a portal shaft type component,the fuselage of the door straightening machine is optimized.First,a three-dimensional model of the automatic straightening machine was established using SolidWorks,and then ANSYS Workbench was used to perform a static fax analysis of the model under extreme conditions to verify whether the body meets the requirements of the working conditions.Simulation results show that the strength of the fuselage meets the requirements,but the stiffness is insufficient.To this end,the thickness and structure of the fuselage have been reasonably improved and made to meet the requirements of lightweight design.The improved structure is simulated and analyzed,and the optimized results are compared with the previous results.The analysis results show that the weight of the improved structure is reduced and the strength and stiffness of the fuselage meet the requirements.
