内容記述
Vibrations originating from chain saw are generally transmitted to the worker's hand, effecting detriment of the physiology. To reduce the transmitted vibrations isolators in the form of spring, rubber mounts, or cork paddings are frequently used.
This report describes the results of the experimental studies obtained by using auto inner tubes(taxi and track wheel) as a possible vibration isolator.
The measurements of vibration transmitted from the chain saw handle to the back of the hand and the hanging device were carried out with accelerometers, dynamic strain amplifier and rapicoder. (Photos. 1 and 2)
From Figs. 4 and 5, it seems possible that the variation level of chain saw handle can be decreased to 60～70% when the rubber isolators are used.
