摘　　要：针对沿海地区台风频发而导致的高耸塔器振动破坏问题,采用理论分析和数值模拟相结合的方法,开展了沿海一高耸塔器在脉动风载荷作用下的动态仿真分析。基于自回归模型法,随机振动理论以及脉动风速频域理论,采用MATLAB和ANSYS软件模拟,获得了高耸塔器在参考风速下的脉动风速时程样本和塔器的顺风向风振时程响应,并通过试验验证了模拟手段的准确性,此模拟手段可为今后分析同类高耸塔器在台风作用下的顺风向风振响应提供技术参考。Damaged problems of high-rise tower＇s vibration induced by the typhoon for coastal areas, the dynamic simulation analysis of high-rise tower which under the along-wind loads was considered by use theoretical analysis and numerical simulation methods. Therefore, the along-wind time-history samples and wind induced responses for high-rise tower were simulated at various wind speeds by using MATLAB and ANSYS software, based on auto-regression model method, random vibration theory and frequency charac-teristic of fluctuating wind velocity. And the accuracy of the simulation was verified by experiment, the technical reference can be provided for along-wind response of coastal high-rise towers.
