Abstract
The reliability of wire cable is evaluated in the use progress by mechanics performance analysis and reliability modeling. The cable is simplified for series-parallel model, considering the effect of Weibull effect and Daniels effect to mechanics performance. First, the strength probability density function of series system having Weibull effect was educed by minimal sequence statistics, and the series system strength is educed for Weibull distribution. Next, the strength computing formula of cable having Daniels effect is analyzed, and the probability density function of cable strength is discussed. Last, the failure-independence hypothesis is not advanced. The reliability of cable is modeled by conditional failure probability modeling and system modeling ideas. The result shows that the reliability model could provide foundation for the reliability design of wire cable and could reflect failure-independence.
