Characteristics of vibration tangible to the tips of fingers have been observed in some conditions of contact with a vertical vibration generator. It is found that the amplitude of same tangible vibration _??_ is represented approximately by _??_
_??_ the amplitude of same tangible vibration in μ
K a parameter in μ
ƒ the frequency per sec
h2 a damping constant
n1 the 1st order natural frequency of the vibration
n2 the 2nd order natural frequency of the vibration
θ the phase angle meaning the degree of contact conditions above equation has been developed from the equation given in the previous report (J. of App. Phy. Japan, Vol. 24, No. 3, p. 118).
It is concluded that the human body can be represented by a fine vibrograph, its characteristic impedance being equal to the product of the sum of impedances of displacement and velocity vibrographs and the impedance of accelerometer, involving the phase angle which represents the contact conditions.
