Vehicle Operating Fault Regularity and its Application in Inspection and Maintenance

To reveal the fault occurrence regularity during actual operation of transport vehicle, based on reliability, maintainability and optimization theory and method, and by the the technical means such as large sample testing, mathematical modeling and multivariate data analysis, after several years of follow-up research, we found that the occurrence of vehicle failts obey Weibull distribution, and given specific failt rate functions. Accordingly, we established a corresponding optimal mathematical model of vehicle maintenance cycle, and got the optimal solution of the model. The results of special organized verify test shows that the model solution is accurate and reliable. If transport vehicles perform the optimal vehicle maintenance cycle, the lowest unit mileage cost of vehicle detection, diagnosis and maintenance would be got.
