Research And Analysis Of Wind-induced Response Of Hyperbolic Cooling Tower

Since the20th century, with the rapid development of industry, the power plant’sconstruction in the world also has got great development, and the cooling tower is an veryimportant component in the power plant. In1965, three cooling towers collapsed under astrong wind in the British bridge power plant, so many scholars realized the importance ofthe research of the response of the cooling tower to the wind load.For a cooling tower in Anhui Suzhou power plant, the mechnical model of the coolingtower is established and the finite element method was used to calculate the mechanicalproperty. Main work and the results are in the following.1. The vibration characteristics of the cooling tower are analyzed using the finiteelement software ANSYS. In the study of vibration characteristics, some factors whichaffected the vibration characteristics of the cooling tower were analyzed separately. Thesefactors include the wall thickness, the elastic modulus, the density, the herringbone columnheight, the cross section of the cooling tower. Based on the numerical simulation, theinfluence of these factors for the vibration characteristics of the cooling tower are discussd.2. In analysis of the response of the cooling tower under wind load, because of thenatural wind is generally classified as the mean wind and the fluctuating wind, thewind-induced response of the cooling tower are simulated separately. The displacement andstress response of the cooling tower are got based on the simulation results. At the sametime, the change trend and the location of maximum of the displacement and stress arepresented. The characteristics of wind-induced response of the cooling tower are analyzedby the computing result.
