摘　　要：以整体质量和上下半圆梁的强度为优化目标,利用ANSYS Workbench对400 MN的预应力钢丝缠绕压机进行最大载荷下的静力学分析,并利用ANSYS Design Xplorer模块进行优化设计,对优化变量参数和优化目标进行相关性分析,验证响应面的模型精度。与实际加工工况相结合,对优化结果进行最终的修改。优化结果表明:优化前最大应力为225.78 MPa,优化后最大应力为231.55 MPa,小于材料许用应力238 MPa,并且压机的整体质量下降了34.1 t,优化率为6.3%,可显著降低生产成本。Taking the overall mass and the strength of the upper and lower semicircular beams as the optimization objectives,ANSYS Workbench is used to carry out the static analysis of a 400 MN prestressed steel wire winding press under maximum load,and the optimization design is carried out using the ANSYS Design Xplorer module to conduct a correlation analysis of the optimization variable parameters and optimization objectives,and to validate the modeling accuracy of the response surface.The response surface modeling accuracy is verified.Combined with the actual machining conditions,the final modification of the optimization results is carried out.The optimization results show that the maximum stress before optimization is 225.78 MPa,and the maximum stress after optimization is 231.55 MPa,which is less than the permissible material stress of 238 MPa,and the overall mass of the press is reduced by 34.1 t,and the optimization rate is 6.3%,which can significantly reduce the production cost.
