摘　　要：为了有效降低铁芯电抗器的振动,提出了一种考虑材料磁致伸缩特性的铁芯电抗器振动优化方法。首先,基于经典J-A模型和二次畴转理论,建立考虑应力的磁致伸缩改进模型,并采用粒子群优化-模拟退火(particle swarmoptimization-simulatedannealing,PSO-SA)算法对改进模型特征参数进行辨识,辨识后的均方根误差不超过3.5,验证了其准确性;然后,建立铁芯电抗器电磁场-结构力场仿真模型,计算得到铁芯电抗器磁场和振动分布;基于多物理场计算和拉丁超立方抽样试验方法,结合灵敏度分析技术,获得各参数对振动的影响规律,并对优化目标和变量进行分层;最后,采用响应面法(response surface methodology, RSM)法和Kriging法对铁芯电抗器的参数进行优化设计,获得不同方法下的铁芯电抗器最佳结构参数。研究结果表明:相比于初始参数,采用RSM和Kriging优化方法下铁芯最大振动位移分别降低了13.93%和24.64%;且损耗和金属导体用量也明显减小。因此,在保证铁芯电抗器性能参数满足要求的前提下,采用Kriging优化方法能够显著降低铁芯电抗器的振动位移,为铁芯电抗器的减振优化提供重要的指导意义。In order to reduce the vibration of the core reactor effectively,a vibration optimization method of the core re-actor considering the magnetostrictive characteristics of the material is proposed in this paper.Firstly,based on the classical J-A model and the quadratic domain rotation theory,an improved magnetostrictive model considering stress is established,and the particle swarm optimization-simulated annealing(PSO-SA)algorithm is used to identify the charac-teristic parameters of the improved model.The root-mean-square error after identification is less than 3.5,which verifies its accuracy.Then,the simulation model of the electromagnetic field and structure force field of the core reactor is estab-lished,and the magnetic field and vibration distribution of the core reactor are calculated.Based on multi-physical field calculation and Latin hypercube sampling test method,combined with sensitivity analysis technology,the influence law of each parameter on vibration is obtained,and the optimization targets and variables are stratified.Finally,response surface methodology(RSM)method and Kriging method are used to optimize the parameters of the core reactor,and the best structural parameters of the core reactor under different methods are obtained.The results show that,compared with the initial parameters,the maximum vibration displacement of the core is reduced by 13.93%and 24.64%respectively by us-ing RSM and Kriging optimization methods.And the loss and metal conductor consumption are also significantly reduced.Therefore,on the premise of ensuring that the performance parameters of the core reactor meet the requirements,the vi-bration displacement of the core reactor can be significantly reduced by using Kriging optimization method,which provides important guiding significance for the vibration reduction optimization of the core reactor.
