本文着重介绍了在焊缝检验和大锻件检验中需应用的横波聚焦探头聚焦曲面的设计理论;计算结果以及试验验证。并与所见论文中普遍采用的球面聚焦超声束在固体中折射后的会聚情况作了比较。
This article focuses on the design theory of the focusing surface of the shear-wave focused probe to be applied in the weld inspection and the forging inspection; the calculation results and the experimental verification. And compared with the convergence of the widely used spherical focused ultrasound beams in a solid after refraction.
