摘要

本文研究了用于在高速气体轴承系统中引入阻尼的橡胶O形圈的动力学特性。由高温橡胶化合物组成的O形橡胶圈的刚度和阻尼系数在100–800频率范围内赫兹。确定了具有频率无关系数的简单公式来表示O形环的粘弹性特性。所提出的公式近似于一般尺寸O形环的刚度和阻尼系数。

Dynamic Characterization of Rubber O-Rings: Squeeze and Size Effects

This paper concerns the dynamic characterization of rubber O-rings used to introduce damping in high speed gas bearing systems. O-shaped rubber rings composed of high temperature rubber compounds are characterized in terms of stiffness and damping coefficients in the frequency range 100–800 Hz. Simple formulas with frequency independent coefficients were identified to express the viscoelastic properties of the O-rings. The formulas proposed approximate the stiffness and damping coefficients of O-rings of general size.
