作为新型牵引动力代表的电力机车和内燃机车,具有许多优点。但是由于构造比较复杂,造价和维修费用也比较高,因此对于机车运用部门来说,如何提高机车可靠性,降低修理费用,从而提高机车运营技术经济效益,是一个很重要的问题。长期以来,电力机车和内燃机车的修理制度仍是沿用蒸气机车的经验,机车到了规定的走行公里数,便要进行所谓的“定期检查范围修”。由于机车零部件的质量和组装工艺水平的差异,常导致运营中的故障,影响铁路运输;而不必要的过早解体修理又使机车不能充分利用,造成原材料和劳动力的浪费,使修理费用增加。因此,对现行的机
Electric locomotives and diesel locomotives represented by the new traction power have many advantages. However, due to the complicated structure and the relatively high cost of construction and maintenance, it is a very important issue for locomotive operation departments to improve locomotive reliability and reduce repair costs so as to improve the technical and economic benefits of locomotive operation. For a long time, the repair system for electric locomotives and diesel locomotives is still based on the experience of steam locomotives. When locomotives reach the prescribed number of kilometers traveled, they carry out the so-called “regular inspection range repair.” Due to differences in the quality of locomotive components and the assembly process level, faults in operation often affect rail transport. Unnecessary premature dismantling and repairing can not make full use of locomotives, resulting in the waste of raw materials and labor and the increase of repair costs . Therefore, the current machine
