Dynamic optimization design of linear motor test-bed based on CAE

Full dynamic optimization design of linear motor test-bed based on CAE

According to the driving characteristics of linear motor, the dynamic characteristics of linear motor test-bed are investigated by using the dynamic time domain analysis of the whole machine, and then the weak links of the whole machine are found out. The design variables are determined by sensitivity analysis, and the sequential quadratic programming (SQP) algorithm and multi-objective optimization method are introduced into the dynamic optimization design of the test bench. The research results show that the test-bed not only meets the dynamic performance requirements under instantaneous impact force, but also realizes lightweight. The successful application of this method in the optimization design of the whole linear motor test-bed provides a good reference value for the design and research of large complex mechanical structures subjected to instantaneous impact in the future.
