【摘要】 从发动机在我国机械工业中的地位出发,分析了发动机可靠性研究的重要意义;在阐述评价发动机可靠性的相关指标时,以美国为代表给出了先进国家发动机可靠性的指标数据,指出了我国发动机可靠性方面存在的问题。同时,论述了发动机常见故障的分布形式以及故障归属的类型,对发动机可靠性的研究具有一定的指导意义;最后,分析了近年我国发动机可靠性下降的主要原因并提出了开展发动机可靠性研究的必要性。更多还原

【Abstract】 Based on importance of engine production in Chinese machinery industry, the significance of study on engine reliability was analyzed. Related evaluation criterion for engine reliability were pointed out, and concrete data for engine reliability in advanced states taken USA as example were given, at the same time problems in Chinese engine reliability were discussed. For this reason the distribution models of general engine failures and classification of the failures were studied which had important significance for engine reliability research in the future; at the same time, the main reason for decrease of Chinese engine reliability in recent years was analyzed and the necessity for study on engine reliability was emphasized.更多还原
