The Influence of Moisture on the Frequency Spectrum of Time Varying Mass Engineering Structure

The frequencies of time-varying mass systems have not been commonly studied in engineering structures as the rate change is generally small compared to overall structure. For silos granular materials, total stored granules can be relatively high silo During flow-in or flow-out granules, system behaves a system. Minor changes moisture content ratio cause their flow characteristics change. influence material inside cylindrical investigated this paper using Variational Mode Decomposition, Hilbert Transform, and Marginal Spectrum processing methods. results show that amplitude frequency vibration vary with materials across different cycles, despite all influencing parameters being kept constant. Such variations response structure mean loads also according principles mechanics. outcomes research further developed into diagnostic tool conditionally monitor structural integrity automatically.
