摘要: 本文分析了YG-5(GJ-85)型油锯上下方向振动的双质量弹簧系统的力学模型,提出了该力学模型与以往所做实验结果的矛盾,并通过实验验证了将YG-5型油锯上下方向的振动简化成双质量弹簧系统的力学模型是不准确的。

Abstract: In this article, we have analysed the traditional mechanical model of the double mass spring system of the YG-5 chainsaw, found the contradiction between this mechanical model and former experimental results of other people, and demonstrated through experiment that it is inaccurate to simplify the vibration of YG-5 chainsaw as a double mass spring system.

Key words: Chainsaw, Vibration, Mechanical model
