基于有限元仿真的EMAT结构优化研究
EMAT Structure Optimization by FEA
摘要
Abstract
As a new way of NDT,electromagnetic acoustic testing is applied to the fields of high tempera-ture and on-line inspection.However,the inefficiency of electromagnetic acoustic transducer(EMAT) limits its application to more fields.In order to improve the efficiency of EMAT,magnets and coils were analyzed based on finite element simulation.The length,width,height and distance of magnets and line weight,length,distance and cycle number of coils were selected as parameters to research the relationship of these parameters with magnetic flux density and eddy current.The optimization results are significant and save time and cost of experiments.关键词
