摘　　要：文中采用ANSYS软件对直管段中的裂纹缺陷进行导波L(0,2)的模拟检测。模拟计算直管道裂纹缺陷并与实验数据进行对比,对直管段裂纹缺陷进行了轴向和周向定位,获得了管道缺陷的L(0,2)反射系数和缺陷程度的关系曲线。By using ANSYS,the simulation detecting of the crack defects in straight pipe by L（ 0,2） guided waves was done in this paper. Comparing the result of straight pipe crack defect and experimental data,the axial and circumferential orientation of the crack defect in the straight pipe section was carried out,and the relationship curve of L（ 0,2） reflection coefficients and the extent of defects were acquired.
