摘　　要：应用ANSYS/LS_DYNA软件对某航空发动机钣金件的三维冲压成形过程进行模拟 ,并对成形后的钣金件回弹进行了分析 ,给出了分析结果并对结果进行了分析总结。分析结果可指导钣金件冲压模具设计 ,可根据分析结果对钣金件的冲压模具进行科学有效的修正 ,缩短模具制造周期 ,提高模具使用寿命 ,得到高质量的钣金件 。The stamping process of the aeroengine sheetmetal has been simulated with the software ANSYS/LS-DYNA and the springback of the sheetmetal has been analyzed. The result is analyzed and concluded, and it can be used for guide of the design of the stamping dies for the sheet-metal parts. And based on the result, the stamping dies can be effectively corrected, the manufacturing cycles of the dies can be shortened, the service lifes of the dies can be extended, and high-quality sheet-metal parts can be produced, which will provide more reliability for the aeroengine.
