摘要:
研究了广义人体-结构-TMD耦合系统的动力学特性.利用2段连续的直杆模拟静立人体,将广义人体和结构均简化为单自由度,并与悬挂于结构下部的TMD共同组成一个三自由度的振动系统.推导出广义人体-结构-TMD系统的无阻尼固有频率、位移反应谱和加速度反应谱,并将结果与二自由度的结构-TMD系统进行对比.结果表明,广义人体对系统的动力学特性具有一定的影响.当结构基频为人体基频的2倍时,这2个系统的无阻尼固有频率差别较小;当结构基频与人体基频接近时,这2个系统的无阻尼固有频率差别明显.
Abstract:
The dynamic characteristics of the generalized human-structure-TMD(tuned mass damper)coupled system were studied. A continuous straight bar with two segments was used to model the static body. The generalized human and the structure were simplified as single-degree-of-freedom, and were combined with the TMD suspended under the structure to form a 3DOF(three-degree-of-freedom)vibration system. The undamped natural frequency, the displacement spectra and the acceleration spectra of the generalized human-structure-TMD system were derived. The comparison results between the 3DOF vibration system and the 2DOF(two-degree-of-freedom)structure-TMD system show that the generalized human-body has some effects on the dynamic characteristics of the system. When the fundamental frequency of the structure is twice that of the body, the difference of the undamped nature frequencies of these two systems is small. When the fundamental frequency of the structure is close to that of the body, the difference is considerable.
