【 摘 要 】

To solve the problems of small welding area and poor welding quality between traditional U-rib and bridge decks, a new type local thickened U-rib (LTU-rib) proposed by bridge experts. In this paper, the simulation software ABAQUS is used to simulate a hot roll-forming process of LTU-rib. Finite element model of hot roll-forming process was established. The influence of the pass design schemes and temperature parameters on the hot roll-forming process was analyzed and discussed. The simulation results show that first scheme is more suitable for hot roll-forming process. Although forming temperature can reduce the roll-forming force and improve the metal fluidity, excessive temperature will lead to redundant deformation. The simulation results provide a reference for the parameters design of actual hot roll-forming process.
