摘　　要：铝合金零件在宇航工业、兵器工业上有广泛的应用,尤其是薄壁壳体类零件,但其制造工艺却不够成熟稳定。为研究液态模锻过程中铝合金薄壁壳体件的塑性变形过程,应用有限元分析分析软件DEFORM,对零件塑性变形阶段进行了仿真计算,针对模拟问题进行了零件质量均匀化改进,采用复合加载工艺保证了零件使用性能上的要求。Aluminum alloy parts are widely used in aerospace industry and weapon industry,especially thin-walled shell parts,but their manufacturing process is not mature and stable.For the purpose of studying the plastic deformation process of aluminum alloy thin-walled shell parts during liquid die forging,this paper uses finite element analysis software DEFORM,to simulate the plastic deformation stage of the parts.Aiming at the simulation problem,the quality uniformity of the parts is improved,and the composite loading process is adopted to ensure the performance requirements of the parts.
