摘　要
随着工业生产和科学技术的发展，机械设备的可靠性、可用性、可维修性和安全性的问题日益突出。汽轮机组作为大型旋转机械，在电力工业中发挥着举足轻重的作用，但是由于汽轮机组结构和系统的复杂性、运行环境的特殊性，汽轮机组的故障较高，且危害也较大，特别是汽轮机组的轴系是出故障较频繁的部件之一。本文通过试验模拟汽轮机轴系典型的不平衡、轴系不对中、支座松动、转子碰磨、轮盘松动等七种故障，将收集到的振动信号用频谱分析的方式进行处理，运用Matlab软件绘制各种故障信号对应的瀑布图、频谱图、功率谱图，并对图形进行分析，总结出了各种故障的频谱特征。
关键词：汽轮机模拟试验故障诊断频谱分析
ABSTRACT
With the development of the industry and technology, the dependability、the practicability、the safety of the mechanism has become important increasingly. As the big circumrotate machine, steamer unit have enormous influence, but because of complexity in the configuration and system of steamer unit, particularity of the running conditions、 steamer unit often malfunction and bring bad influence ,specially the shafting .The experimental equipment is developed to simulate the rotator vibration. The running state of machine is simulated by using different running condition: non-equilibrium mass of the shafting、windage in the shafting、flexible in bearing pedestal 、flexible in turntable and so on .this paper analyzes and discusses vibration signals by using frequency spectrum analysis and uses Matlab to bring waterfall plot、frequency spectrum plot、power plot, and finds the different faults spectrum characteristic.
Key words: steamer Fault diagnoses Frequency spectrum analysis
