摘要
按照空气动力弹性相似性准则设计了中央电视塔准仿气动弹性模型,在大气边界层风洞中进行了实验。应用应变仪测定了塔根部的动态弯矩,利用光纤-光点摄影摄像法测定了塔楼和天线顶端的风振运动轨迹,从而得到了中央电视塔对风响应的有关动态特性。
A spline aeroelastic model of the Chinese Central television ( CCTV)tower,was designed according to the law of similarity and was tested in an atmospheric boundarylayer wind tunnel. The dynamic bending moment was measured using strain gauge.Thelocus of wind induced vibration of the antenna tip and the tower building wais taken by useof the method of light-point of optical fibers,The dvnamic characteristic of response of theTV tower to wind was obtained.
