Identification of Structural Systems Using Walsh Functionsumber of methods available for system identification , some of which have been applied for the identification of dynamic structures. The objective is the determination of specific parameter values of the system model such that the behavior of the system and model output are as close as possible uinsidious 发表于 2025-3-22 06:03:34

The Past and Future of Seismic Effectiveness of Tuned Mass Dampersctiveness of tuned mass dampers under transient type ground excitations such as earthquakes has been studied by several investigators . Grandall and Mark investigated the effect of single-degree-of-freedom tuned mass dampers mounted on single-degree-of-freedom primarstaging 发表于 2025-3-22 13:20:05
Active Minimisation of Vibrational Energy in Periodically Excited Structuresuch as internal combustion engines, a.c. electric motors, gear boxes and aeronautical and nautical propellers are common sources of periodic vibration. Vibration from these machines is transmitted to surrounding structures through the machinery mountings and through acoustic excitation and can resul不可侵犯 发表于 2025-3-22 19:56:12
