Abstract

Abstract:

In this paper， roll stamping technology is introduced into the design and manufacture of trailer chassis. Through continuous molding of high strength materials， an integrated chassis rail is constructed， and the corresponding structural improvement is made for a typical trailer chassis. The stress conditions of the two chassis under full load bending and full load braking conditions are compared and analyzed. The results show that because the roller punching process can realize the processing of ultra-long parts with variable section and one punch， the material improvement， structural improvement and the reduction of the number of main components brought by this advantage make the processing of chassis rail significantly improved in terms of production efficiency and assembly efficiency while realizing the lightweight. In addition， the variable section longitudinal beam based on the high strength sheet greatly improves the designability of the structure， which in turn makes it possible to significantly improve the bearing performance. Compared with the base plate with a fixed load mass of 1.4 t， the optimized chassis can bear the load of 2.4 t， and the deformation of the two is similar.

Key words: trailer chassis, roll forming, lightweight, structure optimization
