摘要:
通过Lagrange方程建立人体-结构耦合系统侧向振动的动力学运动微分方程,通过改变人体与结构的质量比、频率比以及人体的阻尼比,分析了不同参数下单自由度人体模型与单自由度结构的动力学耦合特性,通过实测的一组耦合系统频响函数,证实了人体模型本质是弹簧-质量-大阻尼的弹性系统。理论分析和实验结果均表明,人体与结构间的动力学耦合特性主要取决于人体与结构的频率比、质量比以及人体的阻尼比。
Abstract:
The experimental and theoretical results showed that the dynamics properties of human-structure coupling system mainly depended on the frequency ratio,mass ratio of the human body to the structure and the damping ratio of the human body.Up to now,no recognized model has been developed for human-structure interaction.The differential equation of human-structure coupling system under lateral excitation was established by using the Lagrange equation.The coupling dynamics characteristics of human model and the structure with single degree of freedom were analyzed for different frequency ratios and mass ratios of the human body to the structure,and different damping ratios of human body in.The measured frequency response functions verified that the human body was indeed an elastic system composed of spring,mass and large damping in nature.
