Description

technical field [0001] The invention belongs to the field of forward design of reducers, and relates to a digital forward design method of an RV reducer. Background technique [0002] RV reducer is one of the core technologies of robots. With the development of manufacturing technology, due to its advantages of light weight, small size, large transmission ratio, high precision, high efficiency, and high rigidity, RV reducer is gradually used in machine tools and medical equipment. , aerospace and other fields. The design parameters of the RV reducer are complex and there are many constraints. It is difficult to guarantee the accuracy of the design using the traditional method. In addition, the experimental period of the RV reducer is long and difficult, and it is difficult to achieve a fast and robust design. As an optimization method with strong robustness, good convergence and high parallelism, evolutionary algorithm is suitable for solving multi-objective optimization pr...
