Abstract
A numerical simulation analysis has been conducted for hydroforming of Y-shaped tubes. Five loading paths with different internal pressures from 87MPa to 145MPa have been used. Failure modes are analyzed as follows: the transition zone is depressed and the height of branch-tube is not enough. The thickness of specific spots is analyzed for different stages of hydroforming when internal pressure is 116MPa. The influence of internal pressure on thickness distribution of parts is discussed. Through numerical simulation it is indicated that 106MPa-126MPa is a reasonable range for hydroforming of Y-shaped tubes, but for different internal pressures, the minimum wall thicknesses of parts are different.
