The optimization method of the kernel parameters of multi-stage gear system based on MATLAB

In order to solve the long design cycle, tedious calculations and large in size and other issues of the multi-stage gear system, the core design parameters influencing the transmission are selected as optimization design variables based on the design process of multi-stage cylindrical gear transmission system, the objective function and corresponding constraint conditions realized the whole system area of the minimum have been also derived. Based on above optimization mathematical model, the optimal values have been obtained using MATLAB optimization toolbox and verified with an example. The results show that the whole system area can be reduced to 28.51% by our optimization idea.
