摘　　要：基于金属流动控制成形技术,利用DEFORM软件对涡旋盘背压成形过程进行数值模拟,获得了成形过程中金属流动变形和等效应变分布规律。通过对单层凹模和组合凹模结构进行强度对比分析,确定了合理的模具结构。结合正交试验优化结果进行生产试制,验证了金属流动控制成形技术工艺的可行性和模拟的准确性。实验和模拟结果表明,该背压成形工艺对高厚比大、变壁厚的复杂结构件的生产具有一定的指导作用。Based on Flow Control Forming（FCF）,the scroll backpressure extrusion forming is simulated through the DEFORM software,and the flow deformation of metal forming process and the distribution of equivalent strain were obtained.Single die and combination die were compared through the strength analysis for determining a reasonable mold structure.In order to verify the advantage of FCF,combined with the orthogonal tests for production manufacture,the experimental results verified the feasibility of the process and the accuracy of the simulation.The experimental and simulation results have a guiding role on the production of complex structure with high thickness radio and variable wall thickness.
