摘要：
The paper established a finite element model of DZV674 linear tower (500 kV Shiyang - Wuyi transmission project) by ANSYS and studies its dynamic properties. Its first 10 order modes and natural vibration period are obtained. Based on the principle of Kaimal power spectrum and linear filtering method (AR) for simulation time-history of fluctuating wind speed, power spectrum simulation program of wind-speed is got by using Matlab. The rain load simulation is finished on the former simulation.The dynamic analysis of the transmission tower is calculated subject to wind load and rain-wind load.The results demonstrate that wind is the main design load in rain-wind-induced, but the effect of rain shouldn't be neglected.
