Abstract

In order to meet the requirements of saving and environmental protection, the development of automotive lightweight is imminent. Through the finite element analysis of transmission housing, a method based on improved genetic algorithm is proposed for lightweight automobile transmission housing. To improve the efficiency and accuracy, the Latin method is used in the experimental design to generate test sample points, which combined with the response surface of polynomial technology to create an approximate model. Finally, an improved GA is applied to resolve the optimal parameters. The results show that the mass of gear box is reduced under the premise such as strength, stiffness and vibration resistance. This method can provide certain engineering guidance for the lightweight optimization of gear box.
