人体の振動感覚特性と振動基準

Vibration guideline for passenger and merchant ships (ISO6954) was revised at the end of 2000. The main aim of this revision is to establish compatibility with vibration standard of whole body vibration of human body. (ISO2631-1-1997) In this paper, the transition and features of ISO2631 was introduced at first. Correlation of vibration standard between human body and ships were discussed. A method to represent sensitivity curve was proposed as functions of frequency-weighting curve and vibration severity value. A general mathematical expression for sensitivity curve with folded straight lines and frequency-weighting functions having product of hyperbolas was derived. It became possible to compare vibration standards for different evaluation methods. Some examples of comparison between different ISO standards were discussed.
