| Abstract: | To increase life time and ensure safe operation of wire rope, this paper establishes the relationship of failure cumulative distribu- tion and running time on the base of weibull distribution model,proposes the replacement decision based on reliability. According to present time and condition,the conditional residual time is calculated and the next step maintenance interval is determined. Example analysis shows that the method is feasible. |
