（浙江大學(xué) 杭州 3100270[提要] 多個單體結(jié)構(gòu)之間通過聯(lián)接體結(jié)構(gòu)以一定控制器互相聯(lián)接，就形成了多結(jié)構(gòu)振動控制體系。作者建立了聯(lián)體多結(jié)構(gòu)體系的振動方程，聯(lián)接體作為一個附加質(zhì)點加以考慮。運用快速coc法計算阻尼矩陣不滿足正交條件的聯(lián)體多結(jié)構(gòu)體系在隨機地震動激勵下動反應(yīng)的譜密度矩陣。最后討論了影響控制效果的因素及控制器參數(shù)的優(yōu)化問題。

The motion cquation of conncctcd multi-structure vibration control systcm is cstablishcd, while the conncction structure is rcgardcd as an attachcd mass. A fast CQC algorithm is applicd to calculate the PSD matrices of random rcsponscs of conncctcd multi-structure systcm with non-orthogonal damping matrix undcr carthquake cxcitation. The cxamplcs show the cffcctivcncss of the control systcm. The influcnce factors of control systcm arc invcstigatcd. Finally, optimization for paramctcr of the control systcm is discusscd.
