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 multi-objective optimization design method for a motor, comprising the following steps: S1, establishment of an RSM fitting model; S2, orthogonal optimization. The RSM-based motor orthogonal optimization method of the present invention obtains the relationship between the system response and input variables by analyzing a small amount of test data, and establishes a system mathematical model. On this basis, the orthogonal design method is used to design the test program and apply The established mathematical model predicts the test results, conducts orthogonal analysis and optimization on the predicted results.

Description

technical field [0001] The invention relates to the optimal design of a motor, in particular to an RSM-based multi-objective optimal design method for a motor. Background technique [0002] At present, the optimal design of the motor is to further optimize its structural parameters according to the specific constraints of the motor on the basis of meeting national standards and meeting customer requirements, so as to optimize the performance indicators such as motor efficiency, output power, and thrust. 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 motor optimization and optimization design, and many optimization algorithms for motor optimization design have been generated. These algorithms can help designers quickly find the optimal solution of the objective function, opening up new horizons for motor optimization design. B...
