Tuned mass dampers ( tmd ) and multiple tuned mass dampers ( mtmd ) are the most common and practical among these present passive control methods 在眾多的被動(dòng)控制方法中, tmd和mtmd是最為普遍的一種,也最具有實(shí)用價(jià)值和工程應(yīng)用前景。
In this paper , nonlinear static analysis methods , structural dynamic time history analyses based on structural state equation in hamilton system , multi - mode control theories of multiple tuned mass dampers , and semi active control laws of " on - off " are investigated 本文分析和研究了結(jié)構(gòu)靜力彈塑性分析方法、基于hamilton體系下結(jié)構(gòu)狀態(tài)方程求解結(jié)構(gòu)動(dòng)力學(xué)問題的數(shù)值逐步積分方法、多重調(diào)諧質(zhì)量阻尼器( mtmd )的多模態(tài)控制理論以及建筑結(jié)構(gòu)的半主動(dòng)控制律。
Then the concept of complex multiple tuned mass dampers is presented on the basis of calculating results . secondly , as a result of deducing formulas systematically and making programs to analyze with the software named matlab , the complex multiple tuned mass dampers are obviously more effective in comparison with multiple tuned mass dampers for suppressing vibration of struc tures 其次,經(jīng)過系統(tǒng)地公式推導(dǎo)和matlab編程仿真計(jì)算,繪出被控高聳結(jié)構(gòu)在脈動(dòng)風(fēng)荷載激勵(lì)下,安裝mtmd和安裝復(fù)合mtmd后關(guān)鍵部分質(zhì)點(diǎn)的位移均方響應(yīng)譜,通過對兩種情況下位移均方響應(yīng)譜的比較,證明了復(fù)合mtmd的減振效果明顯優(yōu)于傳統(tǒng)mtmd振動(dòng)控制裝置。
Finally , the optimum dynamic parameters of complex multiple tuned mass dampers themselves are designed from two aspects of theories and engineering examples , consequently attained the study achievement that is quite practical . in summary , complex multiple tuned mass dampers have made better of traditional multiple tuned mass dampers as an improved vibration control method . so it will be widely used in engineering structures design 研究結(jié)論表明,復(fù)合mtmd振動(dòng)控制裝置做為對傳統(tǒng)mtmd的進(jìn)一步完善,不僅保持了mtmd的所有優(yōu)點(diǎn),如有效性,魯棒性,而且具有自身的獨(dú)特之處,如每組mtmd包含的tmd個(gè)數(shù)少,便于設(shè)計(jì)、制造、安裝,并且較之mtmd ,具有更好的控制效果,所以,復(fù)合mtmd振動(dòng)控制裝置有著廣泛的發(fā)展前景。
