Because of the complex constraint effects among layers in multi-layered metallic bellows hydroforming,the stress concentration and defects such as wrinkling and fracture may easily *** is a key to reveal the deformation behaviors in order to obtain a sound *** on the ABAQuS platform,a 3 D-FE model of the four-layered u-shaped metallic bellow hydroforming process is established and validated by *** stress and strain distributions,wall thickness variations and bellow profiles of each layer in the whole process,including bulging,folding and springback stages,are *** deformation behaviors of bellows under different forming conditions are *** is found that the wall thinning degrees of different layer vary after hydroforming,and is the largest for the inner layer and smallest for the outer *** folding stage,the wall thinning degree of the crown point increases lineally,and the difference among layers increases as the process *** displacements of the crown point decrease from the inner layer to the outer *** springback,the u-shaped cross section changes to a tongue shape,the change of convolution pitch is much larger than the change of convolution height,and the springback values of the inner layer are smaller than the outer *** increase in the internal pressure and die spacing cause the maximum wall thinning degree and springback *** changing of process parameters,bellows with deep convolution are easily encountered wall thinning during hydroforming and convolution distortion after *** research is helpful for precision forming of multi-layered bellows.
