摘　　要：提出了可靠性理论应用于机器故障诊断的方法，旨在准确识别故障。使用的可靠性理论包括寿命数据分析法、概率分布干涉模型和系统可靠性理论。文中给出了可靠性理论应用于机器故障诊断的数学模型和应用实例。A method of applying the reliability theory to fault diagnosis of machines for the accurate identification Of faults is presented. The scope of reliability theory made use of includes statistical analysis of life expenditure data, interference inching of probability distribution and system reliability interference. Some mathematical models for the application of the reliability theory to fault diagnosis are given together with some practical examples concerning machines. Fault diagnosis methods based on the reliability theory are featured by the following advantages: physically well-defined, simplicity of mathematical expression, reliability of diagnostic results and easy to master by on site personnel. The application of the reliability theory to fault diagnosis of machine has herewith provided a new and effective way of diagnosing fault in machinery.
