摘要	A new hydroforming process was carried out under the background of applying in forming automobile parts, e.g. an engine cradle. In this paper, investigation of the effect of pulsating loading on formability in engine cradle manufacturing was studied by means of finite element simulations and experiment to discuss the relationship between loading paths and formability of tubes in hydroforming. A significant effect of formability improvement by pulsating load was demonstrated by the simulation results which reveal that the reasons for more homogenous deformation are that the contact friction force between the tube and die, namely flow resistance of metal, is reduced under the pulsating load path condition. The main reason for friction force reduction under pulsating load path is that regular springback by pulsating internal pressure causes the reduction of equivalent contact normal force. The results have practical significance in playing advantages of tube hydroforming in manufacturing hollow components.
