Mechanical impedance and vibration transmissibility measurements were conducted on supine humans using sinusoidal vibrations. The frequencies tested were 1-20 Hz with a constant acceleration amplitude of 0.3 G. The tests were repeated with 4.54 kg pure mass placed on each segment. Both results were used to calculate a multi-degree-of-freedom lumped parameter model. The nonlinear reactions of the body are revealed by comparing the model parameters under "no load" and "load" conditions. When the results are compared with impedance measurements conducted under sustained acceleration, it becomes obvious that the thorax, due to its anatomical design, reacts differently from the remaining body parts.
使用正弦振动对仰卧位人体进行机械阻抗和振动传递率测量。测试频率为1至20赫兹，恒定加速度幅值为0.3G。在每个身体节段上放置4.54千克纯质量块后重复测试。利用这两个结果计算多自由度集总参数模型。通过比较“无负载”和“负载”条件下的模型参数，揭示了人体的非线性反应。当将结果与在持续加速度下进行的阻抗测量结果相比较时，很明显，由于其解剖学设计，胸部的反应与身体其他部位不同。
