Abstract: Aiming at the rationality of the structural design of the steel frame friction welding machine bed and the problem of poor static and dynamic performance, on the basic condition of meeting welding process requirements of the steel claw friction welding machine, the steel claw friction welding machine bed was firstly designed. Based on the finite element analysis of the bed structure, the sensitivity of the design parameters,such as the thickness of the wall thickness and the thickness of the ribs, was analyzed regarding the static characteristics as the objective parameters, and the influence tendency of the parameters on static characteristics was obtained. Furthermore, according to the results of the sensitivity analysis, the design parameters of the initial design were improved.Finally, the improved steel claw friction welding machine bed was obtained, and its finite element analysis was carried out. The results indicate that the static and dynamic performance of the steel frame friction welding machine bed has some improvement and its quality is also reduced.

Key words: steel claw friction welding machine bed; finite element; sensitivity; static and dynamic characteristics
