Abstract
The difference between vertical and horizontal vibration perception was found from consideration of the character of the receptor. The equivalent sense distribution of the vibration perception was measured at frequencies ranging from 0.5–20 Hz. The experiments were aimed at developing the optimal method for vibration damping. The relation between the frequency and the vibration level was found to be described exactly by the transfer function of a second‐order integral system with delay with a pair of complex poles. Under constant frequency and the maximum vibration transmissibility, the ratio of the receptor's damping factor for the horizontal vibration to that for the vertical (at 0.0075) was 1.8. According to the relation between the impulse response and the damping factor, doubling the damping factor causes approximately 13% decrease in the impulse response. Therefore, it was found that the load of vibration on the human body could be decreased by converting a vertical vibration into a horizontal one.
