【摘要】 <正> 只有搞清油锯的振动特性,找出油锯振动的根源并掌握其振动规律,才能有的放矢地制订出减振方案并为新型低振动油锯的研制打下良好的理论基础。一、研究对象和测试仪器研究对象和测试样机,选取西北林机厂生产的GJ-85型油锯,柳州机械厂的051型油锯和苏联的урал-2型油锯。样机皆经磨合和试运转。测试仪器选用YD-8型和YD-1型压电式加速度传感器。前者频率范围2-18KHZ,更多还原

【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.更多还原
