In order to obtain the relevant data of the stability and dimensional consistency of tube hydroforming process on the front support beam for the vehicle body, the typical cross-section dimensional precision, circumferential wall thickness and residual stress of the mass-produced upper and lower front support beams were sampled and measured, and the annual scrap rate was statistically analyzed. The results show that the typical cross-section dimensional precision of front support beam is within ±0.2 mm, the dispersion is lower than 0.2%, the wall thickness distribution is uniform, and the maximum thinning rate is lower than 6%. The average tensile strength in the base metal area of formed part is greater than 436.7 MPa, and the strength in the weld area is higher than that in the base metal area. In addition, the residual stress of front support beam formed part is small, the maximum residual tensile stress is only 78 MPa, most areas are in the state of residual compressive stress, and the maximum residual compressive stress reaches 108 MPa, which is beneficial to improve the fatigue performance. Therefore, the tube hydroforming technology can ensure the consistency of the dimensional precision and the high performance forming of front support beam, and its annual scrap rate is less than 0.3%.
