摘　　要：通过改变凹模圆角半径、压边力等成形参数对0.5 mm厚铝合金板拉深成半球形零件的成形过程进行了仿真模拟,研究了不同成形参数下零件成形过程中的应力应变分布和零件成形后的壁厚分布,揭示成形参数对半球形零件成形质量的影响。为实际生产中提高半球形零件的成形质量和抑制成形过程中板料起皱与开裂提供了一定的参考。By changing the die radius,blank holder force and other forming parameters,this paper simulated a deep drawing forming process on a 0.5 mm thick aluminum alloy plate into the hemispherical part,studied the effects of different forming parameters on the stress and strain distribution and the thickness distribution after forming process,revealed the effects of forming parameters on the forming quality of hemispherical parts.This work has provided some reference for raising the forming quality and inhibiting sheet metal wrinkling and cracking during the actual production.
