摘要：

借助Dynaform软件，模拟分析了在不同拉深凹模圆角半径情况下,模具间隙及压边力等工艺参数对直壁圆筒拉深件外形尺寸及侧壁厚度的影响规律，并得到了该拉深件最优的凹模圆角半径参数，其值比经验公式计算结果小。通过进行两个不同凹模圆角半径的对比拉深试验，验证了数值模拟结果相对于经验公式的准确性和科学性，从而为该类零件拉深工艺方案的优化提供参考。

Using Dynaform software, the influence law of process parameters, such as die clearance and pressure on the straight wall cylindrical deep drawing parts overall dimensions and wall thickness was simulated and analyzed under the condition of different radius of deep drawing die. And the optimal die radius of the deep drawing pieces was obtained, the value of which is smaller than empirical formula calculation results. Comparing two different die fillet radius of the deep drawing test, the accuracy and scientific of the numerical simulation results relative to the empirical formula is verified, which has certain value reference for the optimization of the deep drawing process of such parts.
