| 摘 要： | 基于相似理论，制作了某3层建筑结构的相似结构，建立了一个4自由度的振动系统；根据结构的振动特性对磁流变液阻尼减振器进行了优化设计，求得了磁流变液阻尼减振器的质量、阻尼系数及刚度；设计一套用于建筑结构的半主动振动控制测试系统，对磁流变液阻尼减振器的减振效果进行了试验研究，在同时考虑结构固有频率以及外界磁场强度的情况下，安装磁流变液阻尼减振器能使结构的振幅明显减小，整个振动过程较为稳定，验证了磁流变液阻尼减振器的减振效果。 |

| Abstract: | A similar model is made for three stories building structure based on similarity theory and a 4-DOF vibration system is built up.The parameter of MRF damper is optimized.The coefficients of mass,damping and rigidity are determined according to the characteristics of structure.A set of testing system for semi-active vibration control device used in building structure is designed and the effect on shock absorbing of MRF damper is studied.Taking into consideration the structural natural frequencies and regulating the strength of external magnetic field,swing of structure will be decreased obviously after stalling the MRF absorber and the vibrating process will be more reposeful.The effect on shock absorbing of MRF damper is then validated. |
| Keywords: | MRF absorber semi-active control building structure |
