Health Monitoring for a Structure Using Its Nonstationary Vibration

[摘要] The frequency distribution of a short interval period, the SIP distribution, obtainedfrom the vibration of a structure that is excited by the force of non-stationary vibration is available for the robust estimation of the dynamic property of the structure. This paper shows experiments of the health monitoring of a model structure using the SIP distribution. Comparisons of SIP distributions with average DFT spectra are also shown.
