Abstract Bolt loosening is a common structural failure, which received extensive attention from many industrial
departments. Because the uneven stress on different directions of a bolt is the common reason that
the bolt becomes loose, it is quite important to carry out the research about sensitive detection of bolt
loosening. Using Agilent 4924A instrument, this paper precedes the loosening test of bolts based on
Electro-Mechanical Impedance (EMI), on an aluminum plate instead of flange plate for simplification.
And the electromechanical admittance is given according to the fundamental equation of PiezoMaterial Lead Zirconate Titanate (PZT). Specifically, the More >
