设备使用过程中的故障分布及可靠度变化分析

Study on the Failure Distribution and Reliability Variation of the Equipment in Use

通过对设备故障影响因素、故障分布主要类型、可靠性变化的分析,研究了设备故障的分布类型(指数分布函数,威布尔分布函数),可靠性变化的计算,同时结合具体的实例来分析如何确定故障分布类型,以及如何确定设备可以达到的可靠性水平,并根据实际数据得到了ZW-17/29空压机在使用过程中的故障分布函数、可靠度变化。为制定设备的技术管理和维修管理计划提供理论方法。

This thesis analyzes the factors which lead to the failure of equipment, the type of the failures and the reliability of the equipment. The distribution functions （ such as exponential distribution and Weibuill distribution） of the failures are discussed and the reliability of equipment is estimated. Meanwhile, the methods of identifying the types of failures and the degree of the reliability of equipment are described by an actual example. The Failure Distribution and reliability of ZW - 17/29 Series Air Compressors in use are obtained. It provides the ways to plan the technical and maintenance management of the equipment.
