Abstract

O-rings made from foam rubber are often used in sealing applications. Foam rubber have low (macroscopic) elastic modulus \(E_0\) resulting in a low nominal contact pressure when squeezed against a countersurface. In most cases the foam rubber is covered by a thin surface film with the effective elastic modulus \(E_1 > E_0\). We show that the nominal contact pressure may not be high enough for the contact area to percolate and the O-ring seal will leak. For the leakage calculations we use the Persson multiscale contact mechanics theory, and the (modified) Bruggeman effective medium theory for the fluid flow conductivity. The experimental input for the theory are surface roughness power spectrum, which was obtained from stylus topography measurements, and the elastic properties (\(E_0\) and \(E_1\)) of the rubber O-ring. As an application of this calculation method, we have used the preliminary as well as the final results of the laboratory gas tightness tests of the 136 New Small Wheel Micromegas Quadruplets performed at CERN, from February 2019 to May 2021, in the framework of the ATLAS Experiment upgrade. In the integration quality control, a novel method for gas tightness measurement, that we have called “Flow Rate Loss”, has been used as a baseline method.

泡沫橡胶在密封应用中的使用
摘要 发泡橡胶制成的 O 形圈通常用于密封应用。泡沫橡胶具有较低的(宏观)弹性模量(E_0\),因此在挤压反面时标称接触压力较低。在大多数情况下,泡沫橡胶表面覆盖着一层薄膜,其有效弹性模量为(E_1 > E_0\)。我们的研究表明,额定接触压力可能不足以使接触面积渗透,O 型密封圈会发生泄漏。在泄漏计算中,我们使用了佩尔松多尺度接触力学理论,以及流体流动传导性的(修正)布鲁格曼有效介质理论。理论的实验输入是通过测针形貌测量获得的表面粗糙度功率谱,以及橡胶 O 形圈的弹性特性(\(E_0\) 和\(E_1\) )。作为该计算方法的应用,我们使用了2019年2月至2021年5月在欧洲核子研究中心(CERN)进行的136个 "新小轮微型气体四胞胎"(New Small Wheel Micromegas Quadruplets)实验室气密性测试的初步和最终结果,该测试是在ATLAS实验升级的框架内进行的。在集成质量控制中,我们使用了一种名为 "流速损失 "的新型气密性测量方法作为基线方法。 图表摘要
