一、引言大家知道,在发动机中不可避免地存在着扭转振动,这种有害的振动常使机器设备不能正常工作,甚至造成曲轴或传动轴的疲劳破坏,尤其是在高速、高压的发动机中情况更为严重。因此,减小扭转振动是发动机设计制造中急待解决的问题。目前,在发动机上安装强阻尼的减振器是国内、外用来减小扭转振动的一个主要方法,现有许多发动机厂打算在自己设计制造的汽车发动机中采用尺寸小、结构简单、阻尼效能强的硅油减振器来消除扭转振动。我们为了配合这一研制工作,特在此介绍一下这种减振器的基本理论。
I. INTRODUCTION We all know that there is inevitably torsional vibration in the engine. Such harmful vibration often makes the machine and equipment unable to work normally, and even causes fatigue damage to the crankshaft or the transmission shaft, especially in high-speed and high-pressure engines More serious. Therefore, reducing the torsional vibration is an urgent problem in engine design and manufacture. At present, installing a damper with strong damping on the engine is one of the main methods for reducing the torsional vibration at home and abroad. Many existing engine manufacturers intend to adopt the small size, simple structure and strong damping efficiency in the automobile engine designed and manufactured by themselves The silicone shock absorbers to eliminate torsional vibration. We are in order to meet this research and development, especially here to introduce the basic theory of this shock absorber.
