摘　　要：液压成形是利用液体的压力使工件成不同截面形状的一种塑性加工工艺.介绍了液压成形原理、工艺过程及在工业上的应用,详细说明了管件液压成形设备的组成.用有限元理论和AN SY S软件对液压成形设备中的复合液压缸进行分析,指出其理论应用背景及单元的选择,并用传统的方法对其进行设计计算,将两者比较后得出:计算数值相近,均能满足要求.说明该设计方法正确.Hydro-forming, also called internal high pressure forming, is a kind of plasticity process which exploits hydraulic pressure to make work pieces form different section shapes. This paper introduced principle of hydro-forming, process and application in industry. In addition, constitution of Hydro-forming equipment is presented in details. Analysis of multi-hydraulic pressure cylinder is conducted by adopting FEM theory and the application-ANSYS, in which its application background and selection of units are purposed. Furthermore, analysis is also conducted by utilizing traditional computation methods. Through compare of the two results, it can conclude that the result sought from FEM method is valid, which demonstrates that the method is feasible.
