Optimal Design for Two-Grade Helical Cylindrical Gear Reductor and Its Implementation in Matlab

Reductor is a transmission device which is widely used in mechanical equipment. In order to obtain the design data of reductor, the experiment will be carried out again and again in the traditional design. Although this design data can satisfy the given conditions, it is not optimal. In this paper, through selection of design variables, establishment of objective function and confirmation of restraint conditions, the mathematical model of the optimal design for two-grade helical cylindrical gear reductor was set up. And it can be calculated by using the MATLAB optimization toolbox. Because of the reliability and efficiency, and the simple program of the MATLAB optimization toolbox, the result shows that the efficiency of the mechanical design can be improved by using the method.
