摘　　要：振动信号能够在时域和频域内反映旋转机械的故障信息,针对传统测试系统难以兼顾振动信号高速实时采集和大运算量处理的问题,基于生产者-消费者模式设计了一种旋转机械振动故障诊断系统。该系统将振动信号采集过程与处理过程分别构成数据生产模块与数据消费模块,使数据在两种模块内以不同迭代速率实现高效解耦共享。采用组态软件LabVIEW,并结合高速采集卡NI6351、振动传感器等硬件,搭建了模拟直升机传动系统故障诊断实验台。在生产模块内实现了14通道100 kHz采样频率下的振动信号高速实时采样,在消费模块内采用傅里叶频谱和Hilbert包络谱分析实现了对数据的实时处理,获得了准确的故障特征,实现了对模拟直升机传动系统故障的实时精确诊断。Due to the fact that the vibration signal can reflect the fault information of rotating machinery in time and frequency domains,and in view of the difficulty found in the traditional test system to take into account the high-speed real-time acquisition and large amount of computation processing of vibration signals,a rotating machinery fault vibration test system has been designed based on the producer-consumer mode.In the system,the vibration signal acquisition process and processing process are composed of data production module and data consumption module respectively,so that the data can be decoupled and shared efficiently at different iteration rates in the two modules.By using the software LabVIEW,combined with high-speed acquisition card NI6351,vibration sensor and other hardware,a fault diagnosis platform has thus been built for the simulated helicopter transmission system.The high-speed real-time sampling of vibration signal at 14 channel 100 kHz sampling rate can be realized in the production module,meanwhile,the real-time processing of data can be realized by using FFT amplitude spectrum and Hilbert envelope spectrum in the consumption module,thus obtaining the accurate fault characteristics,as well as realizing the real-time and accurate fault diagnosis of simulated helicopter transmission system.
