摘要：

对某薄板多筋类零件的成形工艺参数进行研究，借助有限元模拟软件对其成形过程进行模拟。基于正交试验方法，并利用数据分析软件，对挤压温度、挤压速度和摩擦系数这3个工艺参数进行优化，从而确定最佳的成形方案为挤压温度480 ℃、挤压速度1 mm·s-1、摩擦系数0.1的等温挤压，零件的最小成形载荷为6.49 MN。此外，为验证正交试验数据的正确性，在仿真及正交优化的基础上，在3000 t压机上进行了挤压试验，得出零件的成形性能与有限元模拟结果一致。研究结果表明，基于正交试验法对大型薄板多筋类零件的挤压成形工艺参数优化是可行的，能够缩短生产周期、提高材料利用率。

The forming process parameters of a thin-plate and multi-ribbed part were studied, and the forming process was simulated by finite element simulation software. Based on the orthogonal test method and data analysis software, the extrusion temperature, extrusion speed and friction coefficient were optimized, and the optimum isothermal extrusion forming scheme was determined with the extrusion temperature of 480 ℃, the extrusion speed of 1 mm·s-1 and the friction coefficient of 0.1, and the smallest forming load was 6.49 MN. In addition, in order to verify the reasonability of orthogonal test data, based on the simulation and orthogonal optimization, the actual extrusion test was conducted by the 3000 t press, and the forming performance of part was consistent with the finite element simulation results. The results show that it is feasible to optimize the extrusion process parameters of large thin-plate and multi-ribbed part through the orthogonal test method, which can shorten the production period and improve the material utilization.
