摘要: The invention discloses a bolt vibration signal correction method based on white noise statistical characteristics for correcting signals detected by detection unit arranged tested bolt. comprises first step of carrying out empirical mode decomposition the in which is carried unit, and n intrinsic function components trend term are acquired, second effectiveness recognition an component module called, according to pre-built approximate entropy distribution interval module, decomposed components, third reconstruction all recognized effective after used reconstructing signals. has advantages that simple, design reasonable, realization convenient, use effects good, can be effectively corrected, real state acquired.
