摘　　要：针对航空发动机振动数据高速实时监测频谱要求较高的问题,通过提高频谱线数进而提高频谱分辨率开发了一套12通道的具备信号采集、信号监测、频谱分析、数据存储、数据查询和生成报表等功能的航空附件传动机匣振动测试系统。该系统即能进行实时高速频谱分析,又能实时查询振动烈度趋势。保证显示器频谱刷新速度的基础上系统软件的实时频谱分析的线数至少为6400线。对提高故障诊断的实时性与精确性具有重要意义。A set of twelve channels vibration measurement system of accessory gearbox for aero-engine is developed to solve the problem of high-speed real-time monitoring spectrum of aero-engine vibration data, which has signal acquisition, signal monitoring, spectrum analysis, data storage, data query and reporting capabilities. The system can perform high-speed real-time frequency analysis and real-time query vibration severity trend whose number of lines in real-time frequency analysis at least reach to 6400,which greatly improve the real-time performance and accuracy of fault diagnosis.
