摘要:
在综合考虑力-磁-声的多个物理场耦合的基础上,通过采用有限元数值仿真方法模拟扭转模态磁致伸缩导波对铁磁性管道的检测,研究激励电流频率对T模态导波检测效果的影响,并通过实验给予验证.结果表明:实验研究数据与仿真计算结果具有相同的变化趋势且存在一个最优频率;激励频率对检测效果有着明显的影响,通过调整激励频率能够使扭转模态导波幅值最大,实现磁致伸缩导波检测性能的优化.
Abstract:
On the basis of considering the coupling of stress-magneto-acoustic multiple physical fields, the finite element numerical simulation method was used to simulate the torsional mode of magnetostrictive guided wave on the detection of ferromagnetic pipe. The effect of excitation current frequency on the guided wave detection of T mode was studied. The experiment results show that the numerical simulation and experiment test have very good consistency. The excitation frequency has a significant effect on the detection effect, and the amplitude of the torsional mode guided wave can be maximized by adjusting the excitation frequency, which can realize the optimization of the performance of the magnetostrictive guided wave detection.
