Abstract:This paper discusses the low vibrational measures and the tests which have been made on the two types of the Chinese high-handled chain saws. We have drawn up many curves on studying the chain saws. These curves are: the time course curve of acceleration, the curve of power chart, the curve of the relationship between the vibrational acceleration and the rotational speed and the curve of the vibrational acceleration in different frequencies.In this paper, we also made preliminary analysis on the vibrational course, the vibrational characteristics and vibrational regularity of the chain saws.
