Abstract

Hot metal gas forming (HMGF) of tubular profiles showed an immense manufacturing potential, due to the excellent strength, lightweight and integrated manufacturing of the formed parts. In the work the influence of forming temperature, pressurization rate and bulging pressure on the of forming law of CR1000/1500HS ultra-high strength steel was studied. Furthermore, the torsion beam design for the hydroforming part optimized as hot metal gas forming was completed, based on the forming characteristics of 1.5GPa ultra-high strength steel, the hot metal gas forming process design, simulation analysis and optimization, Fatigue Strength and life were complete. Compared with the hydroforming part, the hot metal gas forming part had a lightweight effect of more than 28%, and the fatigue life was 36.75 ten thousand times. Thus, the research results provide the basis and reference for the torsion beam to adopt hot metal gas formed parts for 1.5GPa ultra-high strength steel.
