针对输电塔-线体系中输电塔风致响应计算目前存在的不足,提出一种利用完全气弹模型风洞试验测得的若干测点位移来计算输电塔风致响应的方法,该方法同时考虑了气弹效应,塔线耦合效应,塔线体系风振中的非线性。以某输电塔线体系为例说明了该方法应用的全过程并得到了若干结论。拟合过程中采用假设检验的基本方法,得到在95%的置信度下其影响是显著的,验证了该方法的可靠性。该方法同样适用于其他结构,在完全气弹模型风致响应计算中有很大的工程实用价值。
Aiming at the shortcomings of current wind power response calculation in transmission tower and line system, this paper presents a method to calculate the wind response of transmission towers by using some displacement measured by wind tunnel test of full aeroelastic model. The method takes into account both gas Elastic effect, tower-line coupling effect, nonlinearity in wind-induced vibration of tower system. Taking a transmission tower system as an example, the whole process of this method is illustrated and several conclusions are obtained. The fitting method using the hypothesis test of the basic method, obtained under 95% confidence its impact is significant, verify the reliability of the method. The method is also applicable to other structures and has great engineering practical value in the wind-induced response calculation of a complete aeroelastic model.
