An Approach for Analysis of Bulged Profile and Thickness Distribution of Tube in Free Hydro-bulging Process

摘要：

　　Tubular components are widely used in the areas of automotive and aerospace industries due to their excellent properties.A mathematical model considering the bulged region as a parabola curve is proposed to examine the plastic deformation behavior of a thin-walled tube during the free hydro-bulged process.The finite element simulations of the free hydro-bulging process are carried out to verify the approach indirectly.The results indicate that the model is accurate and acceptable to figure out the circumferential radius,wall thickness and axial radius of the bulged profile.
