Abstract：

Tube hydroforming as an innovative process was wildely used in automotive,aircraft and aerospace industry with many advantages such as lightweight,lower cost,high stiffness,etc.This paper aiming at the problem of the match of punch displacement and internal pressure,by means of FEM and experiment,analyzed the influence of loading path on tube hydroforming and presented some relative knowledge for the application of this process.
