1前言我国铁路机车检修采用计划预防修体制,在这种维修体制中,很重要的一点就是要科学合理地确定检修周期。只有当计划维修的周期接近机车发生故障的实际周期时,这种维修计划才是最有效的。检修周期过短,将产生过剩维修,造成不必要的浪费;检修周期过长,将使得机车维修不足,影响机车的运用和安全。因此,机车检修周期应符合机车的实际损耗状况。
1 Preface China’s railway locomotive maintenance plan to prevent repair system, in this maintenance system, it is important to determine the scientific and rational maintenance cycle. This maintenance plan is most effective only when the scheduled maintenance cycle is close to the actual cycle in which the locomotive has failed. Overhaul period is too short, will have excess maintenance, resulting in unnecessary waste; overhaul period is too long, will make the lack of locomotive maintenance, affecting the use of locomotives and safety. Therefore, locomotive maintenance cycle should be consistent with the actual loss of locomotive conditions.
