Review of Experimental Research on Bolt Looseness Monitoring
Bolt connected structures are widely used in engineering fields,such as civil engineering,mechanical engineering and aerospace.However,under the actual working condition,the bolt connection structure bears the alternating load,which inevita-bly leads to a series of failures such as loosening and breaking,resulting in huge economic losses,and even casualties.Therefore,it is very necessary to detect the looseness and monitor the state of bolt connection structure by experimental research.A large num-ber of scholars have studied and built experimental platforms with different function and type of by different methods.In this pa-per,the typical experimental research on bolt looseness fault monitoring is summarized,and the guided wave technology,vibra-tion technology,piezoelectric impedance technology and some other technologies are systematically introduced.The experimental research of bolt looseness monitoring based on the technology is summarized.Finally,some prospects of experimental research and technology are given.It will provide a reference for the experimental study of bolt loosening monitoring,and further promote the application of theoretical research in engineering practice.
