| Through the function detection and failure analysis of the system in the mechanical device,reasonable logical judgment methods are used to prevent possible faults,thereby simplifying maintenance and reducing unnecessary waste to achieve effective system maintenance.This is the "Reliability Centered Maintenance"(RCM).In the process of maintenance and repair of the hydraulic system of the wheel machine,it is of great significance to cite the reliability maintenance concept.It can not only guarantee the continuous operation of the equipment,improve the assembly quality of the wheel,increase work efficiency,reduce the maintenance cost,reduce the pressure,but also can inhibit the inherent reliability of the installation level.This article takes the wheel assembly machine hydraulic system as the research object and studies the maintenance strategy of the hydraulic system.In order to deeply understand the structure and working principle of the hydraulic system of the wheel machine,a reliability block diagram of the hydraulic system was established between the components of the series and parallel relationship between the main system and the node.Combined with the maintenance experience of the railway administrative staff,the press was summarized and summarized.The hydraulic system fault and failure analysis causes the FMEA to perform quantitative analysis on the hydraulic system failure mode;then,using the fuzzy fault tree analysis method,the hydraulic system fault tree was established to qualitatively and quantitatively analyze the fault tree analysis;the hydraulic system passed logic analysis and decision-making.Methods Analysis of failure time and maintenance time distribution model to study the optimal prevention cycle of hydraulic system... |
