Application of Hilbert instantaneous spectrum on improved bolt anchoring quality detection

Abstract The nondestructive testing technology for bolt anchoring quality based on the acoustic reflection method is developing rapidly. Hilbert transform instantaneous spectrum is frequently used. However, due to the existence of the folding phenomenon in the instantaneous phase, the accurate ident...
