| Abstract: | A method of lightweight optimization design for a gear box is proposed based on the approximation model and genetic algorithm(GA).The premise of lightweight optimization is to ensure the performance requirements,such as strength,stiffness and vibration resistance.The Latin method is used in the experimental design to generate test sample points,and the approximation model is built based on the Gaussian radial basis function.The global optimization design is also performed based on the GA.The mass of the opt... |
