薄壁铝合金半球壳塑性成形与模拟技术应用研究

Application research of plastic forming and simulation technology for aluminum alloy thin hemisphere shell

以某铝合金薄壁半球壳功能设计、塑性成形制造工艺过程仿真为对象,通过对比研究4种工艺成形方案,最后得出冲压方案最优,其次为超塑,最次为机械加工。

The function design of an aluminum alloy thin hemisphere shell was presented; and a simulation analysis on the plastic forming process was made. A comparative study on four technological schemes show that the plan of stamping and rolling is optimal, the superplastic forming method is better and the machining method is not so hot.
