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.
