| 摘 要： | 针对目前柱状螺旋线圈EMAT建模不完善,可解算度不高的问题。将线圈等效为单匝导线的矩形面积分,并采用区域特征函数截断法(TREE)对其进行完整地解析建模,得到磁感应强度、涡流、线圈阻抗表达式。通过实际搭建EMAT(electromagnetic acoustic transducer)试验平台,测量对比模型的各参数及变化规律,验证了模型的正确性及可行性。

| Abstract: | Aiming at modeling imperfect cylindrical helical coil EMAT can solver problem is not high. Equivalent to a single-turn coil wire rectangular area points and a regional characteristic function truncation method (TREE) be complete analytical modeling to obtain magnetic induction, eddy current coil impedance expressions. EMAT test platform built by actual measurement parameters and variation of each comparison model to verify the correctness and feasibility of the model. |
