homogeneous design;  Optimize design;  Mechanical design

Considering the limitations of the optimal design method in the field of mechanical design, combined with the uniform design technology and the optimization design idea, a method of optimal design is proposed. Compared with the general optimization design method, this method has the characteristics of simple programming and no strict requirements for the design model behavior, which is a supplement to the mechanical design method. Finally, the idea of using this method to prepare the calculation program and the specific calculation examples are given, and the results verify the feasibility of applying uniform design technology in mechanical design.
