摘要
针对医院CT机房CT设备运行时引起的振动问题,通过对其工作区域动力特性的测试,分析振动环境对工作舒适度及楼板结构安全的影响,并在此基础上对CT机房楼板进行减振改造设计。采取在楼板下安装可调节刚度调谐质量阻尼器(TMD)以及粘钢加固措施,既保证了楼板的承载能力,又有效地减小了设备运行引起的振动。可为类似工程振动分析及控制设计提供参考和依据。
Aimed at the vibration caused by CT equipments in CT room of a hospital,through testing the dynamic 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 running equipment.Reference can be offered for similar project vibration analysis and manage design.
