摘　　要：对液压冲孔过程进行分析,介绍了液压成形同步冲孔的工艺原理,分析了不同类型液压冲孔的特点和应用范围。采用有限元分析方法,建立了液压冲孔仿真有限元模型,并对冲孔过程中应力分布和应变变化情况进行分析。在此基础上,进行液压冲孔工艺试验,把工艺试验结果与有限元分析结果进行比较。结果显示,液压冲孔仿真分析与工艺试验呈现相同的变化规律,仿真分析能够较好预测实际冲孔过程。This paper introduced the hydro-piercing principle, and analyzed characteristics and application range of different hydro-piercing types. The finite element model on hydro-piercing simulation was established, and stress distribution and strain variation were analyzed. On this base, the hydro-piercing experiment was carried out. Result of experiment and FEA were com- pared. The results show that the simulation analysis and the experiment have the same change tendency, and the simulation analysis can predict the actual hydro-piercing process exactly.
