摘要

利用大型分析软件ANSYS建立输电塔有限元模型，并对模型进行简化，从中提取模型的质量矩阵和刚度矩阵，然后基于遗传算法对输电塔简化模型进行自主研发的GMM（Giant Magnetostrictive Material）主动杆件布置位置的优化计算，得出不同数量的GMM主动杆件在输电塔抗震控制中的最优布置位置。同时采用LQR算法对比分析了在一维和三维El—Centro地震波作用下有、无减震控制措施的输电塔位移和加速度地震响应。通过有关参数分析计算，分析表明采取GMM主动杆件进行主动控制能明显衰减输电塔模型的地震响应，具有比较理想的减震效果。

Abstract

The transmission tower model which is simplified is created by the analysis software ANSYS, by which the mass matrix and stiffness matrix of the model are extracted. And then the GMM（Giant Magnetostrictive Material） actuators layout of the simplified model is optimized based on genetic algorithm, the optimal arrangement placements of different number of GMM actuators are calculated. At the same time, the transmission tower seismic responses of displacement and acceleration with control and no control under the action of 1-D and 3-D El-Centro seismic waves are analyzed using LQR algorithm. Based on the parametric analysis, the research shows that the transmission tower seismic responses can be significantly decreased by being active controlled using GMM actuators, and it has ideal damping effect.
