| Abstract: | Traction motor frame's static strength is firstly calculated by Finite Element Method,then dynamic testing of stress spectrum is carried out,and lastly BS standard,which is applied extensively to engineering,is introduced.Based on BS standard,fatigue life of the frame of traction motor is predicted and the result shows that the strength of the welded frame for the traction motor is sufficient. |
