[摘要] 針對(duì)醫(yī)院CT機(jī)房CT設(shè)備運(yùn)行時(shí)引起的振動(dòng)問題，通過對(duì)其工作區(qū)域動(dòng)力特性的測(cè)試，分析振動(dòng)環(huán)境對(duì)工作舒適度及樓板結(jié)構(gòu)安全的影響，并在此基礎(chǔ)上對(duì)CT機(jī)房樓板進(jìn)行減振改造設(shè)計(jì)。采取在樓板下安裝可調(diào)節(jié)剛度調(diào)諧質(zhì)量阻尼器( TMD)以及粘鋼加固措施，既保證了樓板的承載能力，又有效地減小了設(shè)備運(yùn)行引起的振動(dòng)。可為類似工程振動(dòng)分析及控制設(shè)計(jì)提供參考和依據(jù)。

Abstract: Aimed at the vibration caused by CT eqLupments in CT room of a hospital, through testing the dynanuc response in CT equipments working region, the impact of vibration circumstance on working comfort level and the floor safety was analyzed. The vibration reduction transformation design was made on this basis. By installing adjustable stiffness tuned mass dampers( TMD)  and using steel-bonded reinforcement measure, it could guarantee the floor's bearing capacity and reduce effectively the vibration caused by rumung equipment. Reference can be offered for similar project vibration analysis and manage design.
