Lightweight optimization method for motor rotor punching sheet

Abstract

The invention discloses a motor rotor punching sheet lightweight optimization method, which comprises the following steps: based on the working conditions of a motor, selecting several typical working conditions of the motor as the working condition requirement of rotor design, taking all loads of the rotor working under different working conditions as variables, and grouping the loads according to the corresponding working conditions; three-dimensional design software and analysis methods of finite element topological optimization, size optimization and morphology optimization are adopted, optimization design is conducted on the motor rotor punching sheet structure, rigidity and strength are checked, finally, design is guided through optimization, and sample manufacturing and testing are completed. The optimization method can effectively shorten the design production cycle of the product, improve the lightweight design efficiency of the product, and reduce the manufacturing turn and cost of the product design sample.

Description

technical field [0001] The invention relates to the technical field of motor rotor punching, and more particularly, to a lightweight optimization method for motor rotor punching. Background technique [0002] At present, the structural design of the motor rotor punching piece is usually designed by experience. The existing products are scaled with reference to their shape, structure, size and other parameters, and then electromagnetic calculations are carried out, and the rigidity of the empirical formula is checked, and then the sample is tested. Production, complete the relevant performance tests, and finally, depending on the test results, carry out the previous repetitive work, structure optimization, sample production, testing, etc. The traditional design method has the following disadvantages: 1) The design optimization cycle of the product is long; 2) The performance of the product may not be optimal because of the existence of the reference; 3) The structural rigidit...
