Abstract
A method to enhance the thickness uniformity of tube hydroforming part with nonsymmetrical ends is researched. Through numerical simulation and experiments, optimization of nonsymmetrical loading paths and determination of reasonable perform are executed for a hydroforming tubular component. Deformation process and thickness distribution results are obtained and then the effects of the loading paths on thickness distribution are analyzed. With the optimal loading path and perform, axial feeding for nonsymmetrical tubular part is improved and useful wrinkles are formed under better combination of feeding and internal pressure, furthermore the stress-strain state during calibration is improved to get better thickness uniformity and higher forming limit.
