管道T(0,1)模态导波检测数值模拟研究
Numerical Simulation Study of Detection in Pipes Using T(0,1) Mode Ultrasonic Guided Waves
摘 要
简述了管道导波检测理论基础。运用有限元分析方法，对目前现场检测中应用的T(0,1)模态导波在管中传播过程进行数值模拟研究。在模型的特定部位删除或添加部分单元来模拟缺陷和焊缝，对管子的一端切向瞬时位移载荷模拟T(0,1)模态入射波，计算管道的瞬时动力学响应，对回波信号作频谱分析。计算结果表明，缺陷位置可以根据缺陷处回波信号到达时间和波速确定。给出了缺陷回波反射系数与缺陷横截面积各影响因素之间的关系曲线，可近似地判定缺陷的几何尺寸，并通过回波初始相位来识别缺陷。

Abstract
The basic theory of the ultrasonic guided wave detection technique was reviewed. Using the finite element method, numerical simulation studies were performed about the T(0,1) modules applied in the current detection in field. In finite element models, the defect and welding were simulated by getting rid of or add some cells at specific position, and the T(0,1) modules wave-input was simulated with tangent transient displacement applied at one end of pipe. The results showed that the corrosion defect was located by the time of the echo wave and the wave velocity. At the same time, the relationship between reflection coefficient and the geometrical dimension of defection was made. The flaw and the welded joint can be distinguished by the echo initialphase.
