摘要:The protecting effect of the porous elastic materials inserted between the hand and the vibration source was examined by using the driving point mechanical impedance. This paper reports the results obtained with two types of polyvinyl chloride foam, whose shape was the cylinder of 5 cm diameter. One of these two types was found to be available above 30 c/s as the vibration protector. The measuring method of this damping effect was also examined with the mechanical model of the hand.
