摘要

本文旨在确定橡胶在刚玉表面滑动的理论摩擦模型中的激发体积和穿透深度。利用刚玉表面的功率谱密度和橡胶的粘弹性模型实现了克吕佩尔摩擦理论的理论程序。功率谱密度是通过使用轮廓仪进行表面测量计算出的高度差相关函数参数,以幂律模式获得的。橡胶的粘弹性模型参数来自动态机械分析仪。摩擦系数的经验法则是从侧向力实验和实验室磨损测试仪(LAT 100)的模拟中获得的。理论程序得出的摩擦系数与经验摩擦系数相匹配,从而估算出橡胶的穿透深度和激发体积。理论模型和经验模型之间的相关性令人满意。通过估算滑动橡胶的渗透深度和激发体积,可以了解表面尖角附近的接触条件以及摩擦过程中橡胶的耗能体积。

Determination of Penetration Depth and Excited Volume of Rubber in Klüppel Friction Theory from Friction Law
This article aims to determine the excited volume and penetration depth in the theoretical friction model of rubber sliding on a corundum surface. The theoretical procedure of the Klüppel friction theory was implemented using the power spectral density of the corundum surface and viscoelastic model for rubber. The power spectral density was obtained with a power-law mode using the height difference correlation function parameters calculated from a surface measurement taken with a profilometer. Viscoelastic model parameters for the rubber were derived from a dynamic mechanical analyzer. Empirical law for friction coefficient obtained from the side force experiments and simulations of a laboratory abrasion tester (LAT 100) were used in this work. The friction coefficient from the theoretical procedure was matched with the empirical friction coefficient to estimate the penetration depth and excited volume of rubber. The correlation between the theoretical and empirical model was satisfactory. Estimating the penetration depth and excited volume of sliding rubber provides an insight into the contact conditions near surface asperities and the volume of rubber contributing to energy dissipation during the frictional process.

期刊介绍: Tire Science and Technology is the world"s leading technical journal dedicated to tires. The Editor publishes original contributions that address the development and application of experimental, analytical, or computational science in which the tire figures prominently. Review papers may also be published. The journal aims to assure its readers authoritative, critically reviewed articles and the authors accessibility of their work in the permanent literature. The journal is published quarterly by the Tire Society, Inc., an Ohio not-for-profit corporation whose objective is to increase and disseminate knowledge of the science and technology of tires.
