通过内燃机车可靠性分析可知,内燃机车绝大部分的故障均是由于电气设备损坏而造成的。采用一些完全新型的、客观的方法来检测电气设备,这是目前非常重要的任务。采用计算技术的检测方法就是这种方法中的一种,它可以大大地降低检测作业的劳动量,提高检测的客观性、可信性和依据性。 Through the reliability analysis of diesel locomotives, we can see that most of the faults of diesel locomotives are caused by the damage of electrical equipments. It is a very important task to test electrical equipment in some completely new and objective ways. The detection method using computing technology is one of such methods, which can greatly reduce the amount of labor for inspection operations and improve the objectivity, credibility and basis of testing.
