Abstract

In this paper, the current bolt axial stress measurement is investigated and summarized. Bolt transducer method is chosen to take experiments and test. The strain bolt axial stress transducer and optical fiber axial stress transducer are both developed and researched in this paper, which the craft process and experiments are explored and carried out. The testing data is obtained and transducer characteristics are calculated and analyzed.
