Micro Vibration Test and Analysis in Experiment Hall of Beijing High Energy Photon Source Facility Induced by Artificial Frequency Sweep Excitation

  • 摘要: 微振动控制是精密大科学装置在建设过程中的重点关注对象之一,北京高能同步辐射光源(HEPS)项目采用浇筑1 m厚钢筋混凝土结构底板加3 m厚的素混凝土垫层的方式来实现项目要求的微振动控制目标。报道了主体结构完工后,在北京高能同步辐射光源建设施工现场开展的1~100 Hz激振器扫频激励试验。通过对试验中实测得到的振动信号在时域和频域内进行分析,评估北京高能同步辐射光源主体结构完成后实验大厅底板的微振动水平和微振动控制能力。试验结果表明:在1~100 Hz的振动激励下,实验大厅底板表现出良好的振动控制能力。
