This paper presents an experimental investigation to identify the fundamental vertical dynamic parameters (natural frequency, damping ratio and body mass ratio) of the standing human body on a vibrating single degree-of-freedom (SDOF) structure. The human whole-body model was previously derived based on the theory of human-structure interaction. Two groups of people participated in the experiment. The groups consisted of 18 and 38 people and measurements were taken for two different settings of the test rig and at two vibration levels. These experiments consistently showed two resonance frequencies of the highly damped human-structure system. The study demonstrated that the experiments were repeatable; and the dynamic parameters of the standing subjects were independent of the test rig setup and the gender of the subjects. It was also observed that the vibration magnitude had a significant effect on the natural frequency but not on the damping ratio. The mean fundamental natural frequency and damping ratio of the standing human body were approximately 6.6 Hz and 22% in vertical vibrations. This is the first time that the dynamic properties of the standing human body have been determined based on the theory of human-structure interaction.

本文提出了一项实验研究，以识别振动单自由度（SDOF）结构上站立的人体的基本垂直动态参数（固有频率，阻尼比和体重比）。人体全身模型先前是基于人体与结构相互作用的理论得出的。两组人参加了实验。该小组由18人和38人组成，分别对两种不同的测试装置设置以及两个振动等级进行了测量。这些实验一致地显示了高阻尼人体结构系统的两个共振频率。研究表明实验是可重复的。站立受试者的动态参数与测试装置的设置和受试者的性别无关。还观察到，振动幅度对固有频率有显着影响，但对阻尼比没有影响。站立的人体的平均基本固有频率和阻尼比约为6.6 Hz，垂直振动约为22％。这是首次基于人体-结构相互作用理论确定站立人体的动力学特性。
