Sine-on-Random Vibration Test Based on Multi-resolution Spectrum Estimation and Wiener-Khinchin Theorem
Some traditional methods to get the sinusoidal amplitude in sine-on-random vibration test control are analyzed, and then this paper introduces a sine-on-random vibration test control method based on multi-resolution spectrum estimation and Wiener-Khinchin theorem. This method can clearly separate the sinusoidal signal from the wide band vibration signal in the frequency domain, and therefore solves the problem of poor control precision at lower frequency in sine-on -random vibration test. Finally some tests using the method was implemented on shaking table, and the test result comparing to the traditional method shows good control precision at lower frequency.
