框架悬挂结构动力特性与减震性能的理论研究

Theoretical Study on the Dynamical and Shock Absorption Properties of Frame Suspended Structures

文章从框架悬挂结构的运动方程出发 ,推导了此类结构的动力基本方程 ,并从动力基本方程入手 ,导出了主体结构与悬挂楼层振型分量间的关系 ,并进一步得出了悬挂结构的频率计算公式 .该公式建立了悬挂结构的频率与相应普通框架结构的频率、悬吊长度和悬挂楼层与主体结构质量比之间的关系 。

Based on the dynamical equation of frame suspended structures, the structure's frequency equation is established. The achievement can be obtained in the main effect of the frame suspended structure's frequencies, which can offer the foundation for the theory.
