国产高把油锯的整机振动传递路线

摘要

The paper mainly studies high handle power chain saw vibration transmission path, and compares with model py6a and model ypaπ-2 power chain saw made in Russia. We have come to the conclusion of power chain saw vibration is stochastic, and have many influence factors. For solving vibration problem from vibration source, we must use other type of engine. The distribution of power chain saw vibration energy is complicated, passage testing and analysis, we can find the reasonable install position of saw handles. The vibration value characteristic of saw handles is one of the most important factor of influence handfeel vibration. Saw handle of domestic power chain saw have the engine amplification characteristic, but abroad model machine have the engine attenuation characteristic.%研究高把油锯振动传递路线,并与和其类似的前苏联产"дружба"型和"урал-2"型油锯(锯把)进行比较,从而得出油锯振动是随机振动,其影响因素很多,要从振源上解决振动问题,必须考虑采用其他类型的发动机;油锯振动能量的分布复杂,通过振动传递路线测试和分析可以找出相对合理的锯把安装位置;锯把本身的振动值特性是影响手感振动的重要因素之一,国产油锯的锯把具有机械放大特性,而国外样机具有机械衰减特性.
