螺栓横向剪力的超声检测

Ultrasonic testing of transverse shear force in bolt

摘要: 介绍了螺栓轴向应力检测的原理,设计了一种受剪夹具,采用超声检测法研究了在不同扭矩下剪力和时延的线性关系。结果表明,在不同扭矩下,剪力与时延呈线性关系,但斜率不一样,可为超声波法测量螺栓剪力提供依据。

Abstract: The principle of bolt axial stress detection is introduced, a shear fixture is designed, and the linear relationship between shear force and time delay under different torques is studied by ultrasonic detection method. The results show that there is a linear relationship between shear and time delay under different torques, but the slope is different, which can provide a basis for measuring bolt shear stress by ultrasonic method.
