The probabilistic characteristics of estimation of the residual strength and operation lifetime of steel wire rope based on the results of non-destructive testing

Abstract

This article describes a procedure for the probabilistic estimation of the strength indices of steel wire ropes on the basis of the data of magnetic non-destructive testing. The proposed method for the determination of probabilistic characteristics undetection an existing fault of a heterogeneous wire rope structure and the false detection of a fault. The obtained probabilistic estimates of errors of nondestructive testing have been applied for calculations of high-risk and conservative scenarios of the variation of the strength and remaining lifetime of wire rope during its non-fault operation lifetime.
