Abstract：

The finite element model of tube hydroforming was established by the commercial software ABAQUS，and the FE simulations under non-pulsating and pulsating pressures were conducted. The finite element model was verified through tests. The results show that the contact pressure is always less than the hydraulic pressure under different pulsating hydraulic amplitudes and frequencies, and it gradually approaches the hydraulic pressure with the tube bulging. When the tube finishes bulging, the difference between them is about 20%. The larger the pulsating hydraulic amplitude and the frequency are, the higher the fluctuation of the contact pressure is and the closer the contact pressure is to the hydraulic pressure. When the frequency is suitable, the contact pressure is closer to the hydraulic pressure.
