Optimum design of automobile gearbox based on MATLAB

According to the design request and characters of a sort of truck, the optimum mathematical model of the truck' s gearbox is set up to decrease gearbox and axis' s weight when the strength and stiffness of the parts are permitted. The truck' s gearbox is optimized by optimum toolbox of MATLAB. The result manifests that the period can be shortened, the weight can be reduced and the cost can be lowered and a satisfactory result can be achieved through optimizing the parameters of the truck' s gearbox.
