日本1984年机车车辆检修技术的课题重点放在采用现代化以减少机车车辆维修保养费用和确保安全、提高可靠性,对机车车辆的检修技术和机车车辆及机械仪器的可靠性进行了研究。 1.机车车辆检修技术现代化的研究设备的诊断技术现已在工业部门广泛采用。我们对①通过振动对回转和往复运动的机械进行诊断技术;②通过温度检测对机器进行诊断的技术;③通过原子能技术对设备进行诊断的技术等进行了调查,并对它们 The task of Japan’s locomotive and vehicle overhaul technology in 1984 focused on the modernization of the locomotive to reduce maintenance and repair costs, ensure safety and reliability, and examine the reliability of locomotive and vehicle overhaul technologies and rolling stock and mechanical equipment. 1. Locomotive and vehicle maintenance technology Modern research equipment diagnostic technology is now widely used in the industrial sector. We conducted a survey on ① machinery for rotary and reciprocating machinery by vibration; ②technologies for the diagnosis of machinery by temperature; ③techniques for the diagnosis of equipment by means of atomic energy;
