Optimization of Internal Pressure Loading Path for Tube Hydroforming of T-Shaped Tube Based on Dynaform

Abstract:

Take the T-shaped tube as the research object, studied the principles and theory. The paper researched the influence of single liner internal pressure loading path and bilinear internal pressure loading path and the gradient of internal pressure loading path on the forming quality of T-shaped tube with the help of FEA and DYNAFORAM simulation software. The paper researched the each method of forming process, and the relation between wall thickness thinning/thickening and the loading path of internal pressure, compared the similarities and differences. The results show that the gradient of internal pressure loading path is the best way, and the internal pressure should be increased growth rate in the pre-formed, so that get a small thickness reduction part.
