Article Preview

The conception and realization of scale transformation stochastic resonance (STSR) are proposed, which are used to deal with problem of weak signal detection with large parameters that can not be resolved by traditional bistable system based on stochastic resonance. Magnetic flux leakage (MFL) signals inspection for oil well tubing defects is easily destroyed by noise. In order to detect weak MFL signals effectively, the proposed STSR technology is applied to the inspection. The result shows that the STSR technology has the potential application in engineering practice.
