摘　　要：为了寻找注塑机动模板质量和应力值的最佳设计参数,首先在NX软件的三维建模模块中,建立动模板的等质量模型;其次利用Ansys软件对动模板进行有限元分析,得到相应的应力值;最后利用多目标粒子群优化算法,在Matlab中进行寻优仿真模拟试验,得到最佳的质量参数值和应力值。通过相应的模拟试验发现,优化后的动模板质量比原设计参数降低了9.8%,最大应力值降低8.3%,为实际生产中的注塑机动模板优化设计提供了设计依据。In order to find the optimal design parameters for the quality and stress values of injection molding maneuvering templates.Firstly,the equal-quality model of the moving template is established in the 3D modeling module of NX software.Secondly,the finite element analysis of the moving template is performed by using the Ansys,and the corresponding stress values were obtained.Finally,the multi-objective particle swarm optimization algorithm is used to perform the optimization simulation test in Matlab,and the best quality parameter values and stress values are obtained.Through the corresponding simulation test,the optimized dynamic template quality is reduced by 9.8% compared with the original design parameters,and the maximum stress value is reduced by 8.3%.This method provides a design basis for the optimization design of injection molding maneuvering template in actual production.
