摘　　要：应用ANSYS软件对注塑机前模板进行了应力分析与拓扑优化,并应用ANSYS/FE-SAFE软件对前模板进行了疲劳寿命与可靠性分析。对比了模板优化前后的应力、变形及疲劳分析情况。结果表明,优化后的模型质量更小,且最大应力更小、变形更小以及有更好的耐疲劳性能。这为注塑机模板的设计及优化提供了一种实用和有效的方法。Fatigue life reliability analysis of the front platen was made with ANSYS/FE-SAFE software.And static analysis and topological optimal design on the front platen of injection molding machine were done with ANSYS software.The stress,deformation and fatigue life of the optimal platen were compared with the original platen.The results showed that the optimal platen＇s mass was less than that of the original platen.Also,its maximum stress and deformation was lower,and fatigue life was longer.This provided a practical and effective method for future＇s design and optimization of platen of injection molding machine.
