摘　　要：国际广泛认可通用振动标准(VC)曲线作为精密仪器设备微振动控制的指标。振动标准(VC)曲线5个等级分别是VC-A、VC-B、VC-C、VC-D、VC-E,从A到E评价指标趋于严格。传统的混凝土独立基础只能满足VC-C以下的微振的等级,而无法满足VC-D及以上的振动要求。采用空气弹簧隔振系统,能有效降低设备及基础的自振频率,从而大大提高隔振效率,能够满足VC-D以上的振动控制标准,多项多点隔振台混凝土浇筑技术,有效控制了混凝土平整度,保证了成型质量。The VC curve of precision equipment is widely accepted as the index of micro-vibration control in the world.The 5 grades of vibration standard(VC)curve are VC-A,VC-B,VC-C,VCD,VC-E.The evaluation indexes from A to E tend to be strict.The traditional concrete independent foundation can only satisfy the vibration level below VC-C,but can not satisfy the vibration level above VC-D.The air spring vibration isolation system can effectively reduce the natural vibration frequency of the equipment and the foundation,thereby greatly improving the vibration isolation efficiency,and can meet the vibration control standards above VCD.The concrete pouring technology of multi-point seismic isolation platform can effectively control the concrete smoothness and ensure the molding quality.
