摘要

基于压阻效应的基本原理设计和制作自感知垫片及其信号传输系统;此外,利用单螺栓松动识别试验验证自感知垫片检测螺栓松动的可行性,并建立螺栓松动扭矩与其电阻、电导与之间的关系式;在此基础上,提出一种利用自感知垫片并联实现螺栓群松动快速检测的方法,并通过螺栓群松动试验验证该快速检测方法的可行性。研究结果表明：该自感知垫片具有良好的松动识别效果和稳定性;相较于传统检测方法,利用快速检测方法能有效提升螺栓群松动检测效率。

Abstract

Based on the basic principle of piezoresistive effect, a self-sensing gasket and its signal transmission system were designed and fabricated. In addition, the single-bolt loosening identification test was used to verify the feasibility of self-sensing gasket detection bolt loosening identification, and the relationship between resistance, conductivity and bolt loosening torque was established. On this basis, a method for rapid detection of bolt group loosening by using self-sensing gasket parallel connection was proposed, and the feasibility of the rapid detection method was verified by bolt group loosening test. The results show that the self-sensing gasket has good loosening recognition effect and stability. Compared with the traditional detection method, the rapid detection method can effectively improve the detection efficiency of bolt group loosening.
