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。
Aiming at the vibration problem caused by the operation of CT equipment in CT room of hospital, the influence of vibration environment on the work comfort and the safety of floor structure is analyzed by testing the dynamic characteristics of its working area. On the basis of this, design. The installation of adjustable stiffness tuned mass damper (TMD) and steel plate reinforcement under the floor not only ensure the bearing capacity of the slab, but also reduce the vibration caused by equipment operation effectively. It can provide reference and basis for similar engineering vibration analysis and control design.
