摘要
螺栓连接是钢结构中最常见的连接形式,其松动和脱落会使得结构的承载能力降低,导致结构产生安全隐患。为避免工程事故的发生,近年来研究人员提出了许多螺栓松动的检测方法。文章综述了一些常见的螺栓松动检测技术的工作原理及其研究进展,包括压电传感技术、光纤传感技术、数字图像处理技术、敲击声法,并对未来螺栓失效检测技术的发展方向进行了探讨。
The bolted connection is the most common type of connections in steel structures.Loosening and detachment of bolts can reduce the bearing capacity of the structure and lead to safety hazards.In order to prevent engineering accidents,researchers have proposed many methods of detecting bolt loosening in recent years.The paper reviewed the working principles and research advances of some commonly used bolt loosening detection techniques,including piezoelectric sensing technology,fiber optic sensing technology,digital image processing technology,and percussion acoustic method.The future development direction of bolt failure detection technology was also discussed.
