　　The improvement of formability by pulsating hydroforming process of 6016 aluminium alloy tubular part of one car is examined using finite element simulation.The effects of the amplitude and cycle number of pressure in the pulsating hydroforming are investigated.It is found that the observation of deformation behaviours, using different oscillation way of internal pressure, the formability is improved by preventing local defects.The simulation results reveal that the height of ramose tube of 6016 aluminium alloy tubular part is improved from 7.10 to 14.31mm, by optimize the pulsating load curves of amplitude and cycle number on the process of hydroforming.
