摘要
介绍了国内外高柔结构减震装置的研究现状,提出了一种新的高柔结构减震装置,并对该装置进行了原理分析和计算。为了检验该高柔结构减震装置的减震效果,在大型结构振动台上进行了模型试验,实验结果表明,由于减震装置的约束作用,增加了系统的刚度,系统共振频率略有增大,该减震装置具有明显的减震效果。最后,对该减震装置在灾害救生方面上的应用前景进行了展望。
The present situation of study on shock absorber device for highrise and flexible structures at home and abroad was introduced. A new one of shock absorber device was presented and theoretical analysis and calculation for the device were conducted. In order to check the shock-absorbing effect of the device, a model test was carried out on large-scale shaking table. Results show that because of the constraint action of the device, the stiffness and resonant frequencies of the system are slightly increased and the device has obvious effect. Finally the further application of the device to lifesaving in disasters was prospected.
