Description
Summary:Based on the analysis and processing of acceleration signals, the time domain least square method and frequency domain analytic method are proposed to identify the parameters of vibration absorption system. The mathematical model of vibration reduction and Simulink simulation system are established, two parameter identification methods are validated by known system parameters and vibration signals; and then, based on the acceleration signal, the influence of signal processing on identification accuracy is analyzed. The two identification methods proposed in this paper can accurately identify the parameters of the vibration absorption system, Finally, the experimental results show that the two identification methods have good engineering applicability and scientific research applicability.
