空间变化地震动下输电塔-线体系振动控制研究
|
摘要
在考虑输电线的几何非线性基础上,建立了输电塔-线体系的三维有限元计算模型。依据现行《电力设施抗震设计规范》,模拟生成了适合输电塔-线体系的多点地震动时程。利用质量、弹簧单元和阻尼单元模拟了调谐质量阻尼器,并对控制参数进行了优化。运用非线性时程分析方法,研究了多点地震激励对高压输电塔-线体系振动控制的影响。研究结果表明调谐质量阻尼器的减震效果显著,能够有效地减小输电塔的地震响应;仅考虑行波效应和多点激励对输电塔的减震效果影响较小,并且多点激励对输电塔的减震效果优于一致激励,但仅考虑相干效应减弱了输电塔的减震效果。
Vibration control of transmission tower-lines system subjected to spatially varying ground motions is studied.Three-dimensional finite element calculation model of transmission tower-line system considering the geometrical nonlinearity of transmission line is established.Multi-support seismic time histories are generated according to code for design of seismic of electrical installations.Tuned mass damper consists of mass,spring element and damping element,and the control parameters is optimized.Using nonlinearity time history analysis method,the effects of vibration control of power transmission tower-line system under multi-support seismic excitations are investigated.The results show that the damping effect of tuned mass damper is significant,which could effectively reduce the seismic response of transmission tower.There is a tiny influence on the damping effect of transmission tower only considering wave passage effect and multi-support excitation,and the damping effect of multi-support excitations is better than that of uniform excitation,but the damping effect of transmission tower is decreased only considering coherency loss effect.
