Numerical Simulation and Optimization of the YKK355-4 Motor Shaft Welding Structure

Abstract:

Motor shaft is an important component of the electromotor. In the process of motor shaft producing, the motor shaft and the rib plates are usually connected by welding. While in actual use, the structure of the motor shaft may often fracture as a result of the welding, in order to solve the above problem, the structure of YKK355-4 motor shaft and rib plates are modeled and analyzed by using finite element method, and then an optimization on the welding process and shaft structure is performed. By comparison, it is safe to conclude that the welding on both sides at the same time can reduce obviously the welding residual stress and welding deformation and the overall welding quality can be effectively enhanced under the adoption of a 3mm chamfer transition in the connection.
