Abstract:

The paper mainly studies high handle power chain saw vibration transmission path, and compares with model Дружба and model Урал-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.

Key words: power chain saw, endanger of vibration, vibration transmission path, the distribution of vibration energy, the transmission characteristics of saw handle
