摘要
采用ANSYS软件对正交铺层CFRP板电涡流分布进行了有限元仿真。建立了包括线圈、复合材料板和空气区域的三维仿真模型,采用谐响应分析方法对模型电涡流进行了计算,重点给出了CFRP板电涡流分布规律。开展了电涡流分布的影响因素分析,分别研究了探头线圈激励频率、激励电压以及探头与CFRP板之间距离对电涡流分布的影响规律,给出了各因素对电涡流强度和分布形状的影响结果。
Finite element simulation analysis of a typical crossply CFRP board is conducted with ANSYS software.The 3D simulation model including the coil,CFRP board and air region is built.The eddy current of the model is calculated by harmonic response analysis method.The distribution of the eddy current density in the CFRP board is given mainly.Based on the FEA method,the factors,including the excitation voltage and frequency of the probe and the distance between the probe and the CFRP board,which have close influence on the eddy current distribution are all analyzed.The influence results of the eddy current amplitude and distribution shape are obtained.
