摘要
以注塑机前模板的质量为目标函数极小化,在满足约束条件的情况下,获得了合理的筋板结构尺寸,且其最大应力降低了8.88%、最大变形增加了13.33%、质量减小了6.74%,节省了材料,提高了强度.对前模板厚度尺寸动态优化得到其固有频率及振型,其变形主要分布在模板中心孔周围区域并向外递减,增加厚度可以提高最低阶的固有频率及其他各阶的固有频率、改善注塑机的动态性能.
Based on the objective function of mass minimization for the front plate of injection molding machine, the optimization structure of rib dimension is obtained when the constraint condition is satisfied. The maximum stress decreases by 8.88%; the maximum deformation increases by 13.33%, and the mass decreases by 6.74%. The structure saves material and improves strength. Through the dynamic optimization of height dimension, the inherent frequency and vibration type are obtained. The deformation of the front plate occurs mainly around the central hole, and decreases by degree outward. The lowest and other inherent frequencies and the dynamic performance of injection molding machine improve with the increase of the height.
