Abstract：

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.
