钢管混凝土风力发电机格构式塔架抗震性能的试验研究

Experimental Research on Seismic Performance of the Encased Concrete Lattice Tower of Wind-driven Generator

以目前常用的1.5MW风力发电机组锥筒型塔架为参考对象,设计了三肢柱和四肢柱钢管混凝土风力发电机格构式塔架模型。通过对塔架模型进行拟静力试验,对比研究了三肢柱和四肢柱钢管混凝土风力发电机格构式塔架的滞回性能、耗能能力等抗震性能。研究结果表明:三肢柱和四肢柱钢管混凝土风力发电机格构式塔架均具有良好的抗震性能和耗能能力。

Taking the commonly used cone-type tower of 1.5 MW wind generating set as the reference object,this paper designs the models for the encased concrete lattice towers of wind-driven generator with three-limb column and four-limb column,and through pseudo-static test on the lattice tower model,makes the comparative study on the seismic behaviors of the encased concrete lattice towers of wind-driven generator with three-limb column and four-limb column such as the hysteretic behavior and energy-dissipating capacity.The research results show that both the encased concrete lattice towers of wind-driven generator with three-limb column and the encased concrete lattice towers of wind-driven generator with four-limb column have superior seismic behavior and energy-dissipating capacity.
