摘要：

针对静止状态人对结构水平振动特性的影响，建立实验平台，分别测试并分析了质量块-结构系统、单人-结构系统、多人-结构系统水平自振频率与阻尼比变化规律.给出了两种人-结构系统静态水平耦合模型的比较分析以及人体的水平振动频率估计.结果表明：在分析静止状态下人对结构水平振动特性的影响时，人体不可简单作为质量块或质量-弹簧-阻尼系统，而应看作带人体刚性质量的质量-弹簧-阻尼系统.结合实验测试数据和人-结构系统水平耦合模型，得到人体水平前后向频率范围为0.236~3.748 Hz，人体水平左右向频率范围为0.194~5.32 Hz.

Abstract:

To study the impact of human body in the stationary state on the lateral vibration performance of structure, an experimental platform is built up and the horizontal natural frequency of the vibration and the damping ratio of the mass-structure system and the human-structure systems are tested and analyzed. Two static lateral coupling models of the human-structure system are used, to obtain the range of the lateral vibration frequency of human body. It is shown that the human body in the stationary state could not be simplified as a mass block as in a mass-springs-damping system to evaluate the impact of the human body on the lateral vibration performance of the structure, and a mass-spring-damper system should be adopted with the human body as a rigid mass. Based on the experimental data and the human-structure coupling model, the ranges of the lateral frequency and the fore-and-aft frequency of the human are calculated, with the results of 0.236~3.748 Hz and 0.194~5.32 Hz, respectively.
