Problems solved by technology

If only the influence of a single parameter is considered, it is easier to optimize the parameters of the linear magnetic gear, but in fact, when optimizing the design, the parameters that need to be considered are not unique, and there are mutual couplings between the parameters, and the optimization of a single parameter does not represent the whole Optimal, comprehensive consideration is required to obtain the best parameter matching

Abstract

The invention discloses an RSM-based motor multi-objective optimization design method. The method comprises the following steps of S1, establishing an RSM fitting model; and s2, carrying out orthogonal optimization. According to the RSM-based motor orthogonal optimization method, the relation between system response and input variables is obtained by analyzing a small amount of test data, a systemmathematical model is established, on the basis, an orthogonal design method is adopted to design a test scheme, the established mathematical model is applied to predict a test result, and orthogonalanalysis and optimization are carried out on the prediction result.

Description

technical field [0001] The invention relates to the optimal design of motors, in particular to an RSM-based multi-objective optimal design method for motors. Background technique [0002] At present, the optimization design of the motor is based on meeting the national standards and customer requirements, and further optimizing its structural parameters according to the specific constraints of the motor, so that the performance indicators such as motor efficiency, output power, and thrust can be optimized. This problem is a complex nonlinear programming problem. In recent years, with the rapid development of computer technology, the optimization theory of modern mathematics has been gradually used in the optimization design of motors, and many optimization algorithms for motor optimization design have been produced. These algorithms can help designers quickly find the optimal solution of the objective function, opening up a new world for motor optimization design. But at pr...
