摘　　要：机械状态监测和故障诊断技术,在生产实践中发挥了重要作用。机械状态监测能够对机械设备运行状态进行实时监测,故障诊断能够判断机械设备故障的类型及发展趋势。本文介绍机械设备状态监测和故障诊断相关理论和提高故障确诊率的措施,重点介绍基于振动信号的检测技术在机械诊断中的应用,并对机械诊断的发展趋势进行展望。Mechanical condition monitoring and fault diagnosis technology play an important role in production practice. Mechanical condition monitoring can be real-time monitoring of mechanical equipment running status, fault diagnosis can determine the type of mechanical equipment failure and development trends. In this paper, the theory of condition monitoring and fault diagnosis of machinery and equipment and measures to improve the rate of diagnosis are introduced. The application of vibration signal based detection technology in mechanical diagnosis is introduced, and the development trend of mechanical diagnosis is forecasted.
