active vibration isolation and its application and development 主動(dòng)隔振技術(shù)及其應(yīng)用與發(fā)展
research on active vibration isolation system of sonar platform 聲納安裝平臺(tái)主動(dòng)隔振系統(tǒng)的研究
the simulation results show that the active vibration isolation system has much better isolating performance against conventional passive isolation system in a very broad frequency range 結(jié)果表明,該主動(dòng)隔振系統(tǒng)在整個(gè)頻段均具有很好的隔振效果。
as they are n't able to isolate the low-frequency vibration, the author does an emphatic research on the single-layered and double-layered active vibration isolation system 由于被動(dòng)隔振不能隔離低頻振動(dòng)信號(hào),據(jù)此作者重點(diǎn)研究了單級(jí)和兩級(jí)主動(dòng)隔振系統(tǒng)。
(2 ) the dynamic models of a specific precise instrument in spacecraft are established and an active vibration isolation system based on piezoelectric intelligent structures is constructed (2)對(duì)某特定的機(jī)載精密儀器進(jìn)行了動(dòng)力學(xué)建模,建立了壓電智能結(jié)構(gòu)主動(dòng)隔振系統(tǒng)。
