为解决钢制平衡块在实际生产中挤压速度和加热温度难以进行有效控制的问题,基于Deform-3D软件对该零件进行温塑性成形计算机仿真加工,整理模拟结果并借助Matlab软件进行双因素方差分析,确定出影响钢制平衡块铆钉长度和挤压力的主要因素。同时,对等效应力数值进行回归分析,获得了一元非线性回归方程并通过验证,最后将由数值模拟试验获得的最佳工艺参数应用于实际生产,获得较好效果。
In order to solve the problem that it is difficult to effectively control the extrusion speed and the heating temperature of the steel balance weight in actual production, the part is subjected to the temperature plastic forming computer simulation processing based on the Deform-3D software, the simulation results are arranged and the two-way variance Analysis, to determine the impact of steel balancer rivet length and squeeze the main factors. At the same time, the regression analysis of equivalent stress values was carried out, the univariate nonlinear regression equation was obtained and verified, and finally the best process parameters obtained from the numerical simulation experiments were applied to the actual production to obtain better results.
