Abstract:

We simulated fluctuating wind load with resonance wave superposition method and validated its effectiveness with windinduced vibration response of a meteorological tower under fluctuating wind load as a subject. We also acquired fluctuating wind load instances applied at every layer of the tower. We further established 3D finite element analytical model for the tower and calculated windinduced vibration response of the tower with time domain analytical method. This provided a necessary reference for early design and vibration control of a meteorological tower. Analytical results show that its maximum windinduced vibration displacement is 0.013 meters under wind load of once in fifty years. This is in the range of design requirements, so the tower design is reasonable.

Key words: meteorological tower structure, windinduced vibration response, resonance wave superposition, simulation of fluctuating wind load
