摘要:
采用振型叠加法对悬挂结构系统的运动特性进行分析研究; 通过对悬挂子结构和主支撑结构的相互作用进行频域分析,提出地震动激励下悬挂子结构对主支撑结构的作用是在主支撑结构上添加悬挂子结构的复惯性质量,即悬挂子结构静态和动态质量(悬挂子结构振动作用与引起振动的外界激励加速度的比值)之和; 根据悬挂子结构的复惯性质量和主支撑结构的模态参数,对悬挂结构系统的耦合动态响应进行了频域研究,采用时程分析方法对结果进行验证; 同时,对悬挂结构系统与TMD/MTMD的减震原理进行了比较分析。
Abstract:
Suspension primary-secondary structures dynamic characteristics in both time domain and frequency domain were investigated. Complex inertia mass was presented, which was equal to the sum of statistic and dynamic mass, and was equal to the specific value of the vibrating excitation and the vibrating action output of suspension secondary structure. Therefore, the action from suspension secondary structure to primary structure in earthquake excitation was equal to that complex inertia mass of secondary structure was added on primary structure. Based on complex inertia mass, the coupled dynamic characteristics of three suspension structure systems models in different modal frequency overlapping scale between suspension primary structure and secondary structure were studied. In addition, it was compared with the shock absorption principium of TMD/MTMD.
