| Abstract: | An electric motor bracket strength is simulated and optimized the finite element method. It is accuracy and efficiency to simulate the effect of load mass by combining with rigid element and concentration mass element. The results show that there is a large stress value at the end part of support position, which may lead to strength failure. To reduce the failure risk of electric motor bracket, a new support bracket is designed by structure optimization. |
