Abstract

A novel type of tailless FBG smart bolt with good performance is developed. Owe to the innovative design of an integrated FBG sensor comprising a strain measured FBG and a temperature-compensated FBG, the tailless FBG smart bolt serves the purpose of torque monitoring or bolt looseness monitoring. We use a theoretical approach to establish the linear correlation between the applied torque and the central wavelength of the tailless FBG smart bolt. Additionally, a newly designed M24 bolt with a nominal strength has been integrated as a crucial component of the tailless FBG smart bolt. To enable the experimental study, the tailless FBG smart bolt is newly designed, fabricated and tested. The experimental results show a strong linear correlation between the applied torque and the central wavelength of the tailless FBG smart bolt, showing good agreement with the theory.

摘要

开发出一种性能良好的新型无尾光纤布拉格光栅（FBG）智能螺栓。由于采用了创新设计的集成FBG传感器，该传感器包含一个用于测量应变的FBG和一个温度补偿FBG，无尾FBG智能螺栓可用于扭矩监测或螺栓松动监测。我们采用理论方法建立了施加扭矩与无尾FBG智能螺栓中心波长之间的线性相关性。此外，一种新设计的具有标称强度的M24螺栓已被集成作为无尾FBG智能螺栓的关键部件。为了进行实验研究，新设计、制造并测试了无尾FBG智能螺栓。实验结果表明，施加扭矩与无尾FBG智能螺栓的中心波长之间存在很强的线性相关性，与理论结果吻合良好。
