摘要:

基于2E2-SZ2型220 kV输电塔结构的三维空间分析模型,考虑结构节点间的风速时程相关性,采用线性滤波法中的自回归(autoregressive,AR)模型,利用Matlab与Visual C++的混合编程技术,编制了高压输电塔结构的空间三维风速时程模拟程序。通过算例分析证明了其准确性和有效性,可为输电塔线的风振响应分析提供参考。

Abstract:

In this paper, a 3D space analyzing model is built for the structure of 220 kV 2E2-SZ2 transmission tower. The wind speed time-histories relativity between the nodes of the structure is considered, the autoregressive (AR)model is adopted. Under the application of Matlab and Visual C++ mix-programming technique, a 3D wind speed time-histories simulation program of high-voltage transmission tower is developed. The calculation sample shows that the model is accuracy and effective. The model can be referenced in the future analysis of wind-vibration response for the transmission lines.

Key words: 输电塔, 风速时程, 自回归(AR)模型, 混合编程
