OBJECTIVE
The purpose of this study was to investigate the apparent mass of the sitting human body and to compare it with current experimental data and the ISO 5982 standard impedance model.
METHOD
The apparent mass of the seated human body in the vertical direction was measured. Twelve male subjects were exposed to random whole-body vibration of frequency range (1-20 Hz), with a vibration excitation level of 1.0 m/s2 r.m.s. The body posture was upright with no backrest contact.
RESULTS
The obtained apparent masses were compared to the International Standard, (ISO 5982). The biodynamic response of the seated Japanese subjects peaked in the 4-6.5 Hz frequency range, which is little bit higher than the reported range of fundamental frequencies (4.5-5 Hz) in most other studies which used different experimental conditions. The outcomes show a clear difference between apparent mass of Japanese subjects and ISO 5982 data.
CONCLUSION
It is not sufficient to apply the ISO 5982 standard to Japanese vehicle design or dummy design.
目的
本研究旨在调查坐姿人体的表观质量，并将其与当前实验数据及ISO 5982标准阻抗模型进行比较。
方法
测量了坐姿人体在垂直方向上的表观质量。12名男性受试者暴露于频率范围为1至20赫兹的随机全身振动中，振动激励水平为均方根值1.0米/秒²。身体姿势为直立，不接触靠背。
结果
将获得的表观质量与国际标准（ISO 5982）进行了比较。坐姿日本受试者的生物动力学响应在4至6.5赫兹频率范围内达到峰值，这比大多数使用不同实验条件的其他研究报告的基频范围（4.5至5赫兹）略高。结果表明，日本受试者的表观质量与ISO 5982数据之间存在明显差异。
结论
将ISO 5982标准应用于日本车辆设计或假人设计是不够的。
