| Abstract: | he variation of folding points during the wire breaking process of a steel wire rope is analyzed.TMe rationality of the analysis of test data by spline function is discussed.A newdimension-reducing algorithm is proposed for the calculation of the parametric variable. It issimple and can be easily handled with a computer. The missing data can be estimated by in-terpolation and the tendency of the variation of test data can be predicted by extrapolation.The work will provide both a theoretical and a methodical basis for the on-line estimation ofthe residual strength and residual life time of the wire rope by the fault diagnosis device. |
