摘要
旋转叶片振动的测量可保证高速旋转叶片在使用中性能稳定。介绍一种采用白光光源低噪声的旋转叶片振动自动测量系统 ,采用快速傅里叶变换 (FFT)对检测结果进行频谱分析。
Rotor blade vibration measurement kept the high-speed rotating blades stable in property. A low noise automatic vibration measurement system was presented in which white light illuminant was used. Spectrum analysis of the results was carried out by fast Fourier transform.
