摘要
从兰姆波检验参考曲线的绘制与参考、对比试块设计与制造、探头的制作、反射回波与质点振动方向关系等方面,对金属薄板兰姆波检验进行了探索,得出了一些新的试验结果和认识.
Nondestructive inspection of metallic plates by Lamb waves was studied, including the drawing and utilizing of the reference curves of Lamb wave characteristic equations, the design and making of reference blocks and transducers, as well as the relationships between the amplitudes of echoes and the directions of displacements. Test results were obtained.
