Research On The Dry Coal Shed Net Shell Structure Of Qianxi Power Plant Based On Wind Tunnel Test

Based on the rigid model wind tunnel test of the dry coal shed net shell structure of Qianxi power plant, this thesis has conducted the research to the superficial average wind pressure and the pulsation wind pressure of the dry coal shed net shell structure according to the wind pressure data of the wind tunnel test, and has analyzed the distributed situation of the average wind pressure. Through the summary of change rule of average wind pressure along with the wind angle, this thesis has obtained the most disadvantageous wind angle on the surface of the dry coal shed net shell structure. This thesis has also analyzed distribution situation of the pulsation wind pressure and its change rule along with the wind angle, and summarized interrelation of the pulsation wind pressure and the average wind pressure.According to design parameter of the Qianxi power plant dry coal awning net shell, structure, this thesis has established the finite element mode of Qianxi power plant dry coal awning net shell structure. Carrying on the modality computation of this model by the ANSYS finite element analysis software, obtains the base frequency and the modality of the structure, and has analyzed change situation of the structure self-oscillation characteristic along with the step number. This thesis compiles computational procedure by using the MATLAB software to calculate the response of wind oscillation, has analyzed change rule of the displacement response of wind oscillation and the load response of wind oscillation along with wind angle. Through the computation and the comparison of the displacement wind oscillation coefficient and the load wind oscillation coefficient, the thesis has analyzed their serviceability of surface wind load computation regarding the greatly cross net shell structure, and has calculated the displacement wind oscillation cofficient which can be applied in this project...
