In order to solve the problems of large similarity of the reducer box and low brand recognition of manufacturers,the design concept of integrating the technical requirements of the box,the connotation of corporate cultural and traditional Chinese culture into the appearance of gearbox was proposed.The finite element analysis method was introduced into the traditional design process of reducer box, and Creo2.0 was used for 3D design and modeling. Ansys Workbench was used for finite element analysis of the design model. The design method of integration of shape and structure was put forward. Through the method, the purpose of improving the brand recognition degree of each reducer manufacturer was achieved, so as to improve the competitiveness of products, enhance the innovation of product modeling, and improve the efficiency of modeling design.
