碩士 === 國立高雄應用科技大學 === 模具工程系 === 103 === In this paper, finite element simulation software LS-DYNA 3D simulation SUS304 stainless steel pipe in the role of a back-putt hydraulic bulge forming a T-shaped pipe. Construction of T-shaped tube of hydraulic bulge forming model to simulate the hy-draulic bulge forming in the coefficient of friction between the different molds and pipe to assess the overall process of bulging, correction, forming phases at different load conditions, such as bloating and correction fluid pressure and the axial direction of the push rod stroke phase relationship, as well as between the push rod to the axial direction perpendicular to the forming stage different stroke ratio. When the load is related to the optimization, the thickness of the T-shaped pipe can keep the top of the manifold, not due to excessive thinning and cracking, and easy to produce wrinkles at the corner of the shoulder to get the best height and appearance.
