【摘要】：扭轉(zhuǎn)調(diào)諧液柱阻尼器(torsional tuned liquid column damper,TTLCD)是一種有效的扭轉(zhuǎn)振動(dòng)控制裝置.本文對該阻尼器在偏心框架結(jié)構(gòu)中的設(shè)計(jì)方法進(jìn)行研究,針對不同的傾斜管道投影點(diǎn)和傾斜角,建立了三種形式的扭轉(zhuǎn)調(diào)諧液柱阻尼器在地震作用下的運(yùn)動(dòng)方程和控制力方程,給出TTLCD參數(shù)優(yōu)化的具體公式,其方法為對比扭轉(zhuǎn)調(diào)諧液柱阻尼器-偏心結(jié)構(gòu)和扭轉(zhuǎn)調(diào)頻質(zhì)量阻尼器(torsional tuned mass damper,TTMD)-偏心結(jié)構(gòu),將兩控制系統(tǒng)轉(zhuǎn)化,利用Den Hartog或Ikeda給出的調(diào)頻質(zhì)量阻尼器(tuned liquid mass damper,TMD)參數(shù)優(yōu)化公式來實(shí)現(xiàn)TTLCD參數(shù)優(yōu)化,最后給出TTLCD的設(shè)計(jì)流程.通過對一個(gè)四層偏心框架結(jié)構(gòu)進(jìn)行模擬,驗(yàn)證了理論設(shè)計(jì)方法的合理性.
[Abstract]:Torsional tuned liquid column damper (torsional tuned liquid column dampert TTLCD) is an effective torsional vibration control device. In this paper, the design method of the damper in eccentric frame structure is studied. According to the different projection point and angle of inclined pipe, the motion equation and control force equation of torsional tuned fluid column damper under earthquake action are established. In this paper, the formula for optimizing the parameters of TTLCD is given. The method is to compare the torsional tuned liquid column damper-eccentricity structure and the torsional FM mass damper (torsional tuned mass damper-TTMD) -eccentricity structure, and transform the two control systems into two control systems. The parameter optimization formula of FM mass damper (tuned liquid mass damper TMD) presented by Den Hartog or Ikeda is used to realize the parameter optimization of TTLCD. Finally, the design flow of TTLCD is given. The rationality of the theoretical design method is verified by simulating a four-story eccentric frame structure.
