| 摘 要： | 为了深入了解自行组装模式下地震模拟振动台的性能,基于地震模拟振动台的组成及工作原理,提出了振动方向、驱动方式、台面尺寸及控制模式等方面振动台参数的设计与分析方法,阐述了系统的动态性能分析以及组成部件参数的优化过程.东南大学自行组装的振动台系统参数设定为单水平向,电液伺服驱动,钢焊结构台面,台面尺寸6m×4m,最大承载模型重30t,最大加速度1.5g,最大速度600cm/s,最大行程±250mm,最大激振力±1 000kN,频率范围0.1~50Hz。在空荷载和钢架模型荷载情况下,利用EL-Centro地震波、Taft地震和Kobe地震波在压缩比为1∶1,1∶2,1∶3,1∶4的情况下进行地震模拟试验,波形相干系数均大于0.75.试验结果表明,这种组装振动台的波形失真小,动态性能稳定,可以满足大部分抗震试验的需要.
