摘要
人与结构相互动力作用可以将人的动力特性与结构动力特性耦合,并使耦合体系产生新的动力特性,已成为柔性结构人致振动以及舒适度研究中的一个重要领域。针对人与结构相互作用模型以及相互影响机理,国内外学者开展了一系列试验研究和理论分析。本文首先介绍了相互作用荷载的测量和建模方法,然后针对相互作用人体动力模型、人与结构相互影响的研究进展进行阐述。已有的研究结果表明,人作为重阻尼动力系统能够增加结构阻尼,改变结构频率;结构振动能够影响人的运动方式,从而改变人致荷载,同时,不同幅值、频率的振动使人体动力参数在一定范围内变化。最后,从人致荷载测量、人与结构相互作用耦合系统和结构振动对人的影响3个方面展望了人与结构相互作用的研究方向。
The human-structure dynamic interaction refers to the coupling of dynamic characteristics between structure and human, and the coupled system develops new dynamic characteristics. It has become an important field in the study of human-induced vibration and vibration serviceability of flexible structures. A series of experimental studies and theoretical analyses have been carried out on the interaction model, and the interaction mechanism between human and structure. In this paper, the measurement and modeling of human-induced load were briefly described firstly. Then the research progresses on the human dynamic model and the interaction between human and structure were introduced. The results show that man as heavily damped dynamical systems can increase the damping and change the frequency of structure depending on the relationship between fundamental frequency of human body and structure. Meanwhile, the vibration of the structure can affect the motion of human and change the human-induced load. Also, the vibration with different amplitudes and frequencies makes the dynamic parameters of human body vary in a certain range. Finally, the future research is prospected from three aspects: human-induced load, interaction between coupling system and effect of structure vibration on people.
