Title: Simulation Study of the Impact of Loading Paths on Hydroforming of Tubes with Variable Cross Sections
Abstract: By using Dynaform software,the impact of loading paths of axial feeding and internal pressure on hydroforming of tubes with variable cross sections is discussed based on the appropriate amount of the total axial feed and the maximum internal pressure.Results indicate that the double linear loading pattern in which the feeding speed in anterior stage is larger than that in the posterior is the best loading path,and the step-loading pattern excels the linear loading pattern a lot,and the step-loading pattern reaches its optimization when the feeding pressure falls into 40~60 MPa.
