针对当前急需解决的全电动曲肘式注塑机尾板的结构优化问题,通过对尾板实际工况下的拓扑优化分析,给出了全电动式注塑机尾板的拓扑优化结构,从而揭示了尾板上的质量减轻优化部位。通过对尾板拓扑优化模型的进一步有限元分析,就模型的各质量减轻部位对尾板的应力和变形的影响情况进行了验证,完善了尾板的模型。该研究为尾板的最终优化结构给出了实际性的指导。

The optimization structure of the rear platen of fully electric injection molding machine is urgent to be solved. Based on the real load and constrain condition of the rear platen, using the topology optimization innovation study method, the final structure optimization solution was given. This topology optimization structure revealed the locations which the material can be removed on the rear platen. The further finite element analysis on this topology optimization structure verified the affect of stress and deformation on the rear platen which was caused by each removed material location on the rear platen. The rear platen structure was improved. This study provids valuable guidance for the optimization structure of the rear platen.
