摘要

本文旨在设计一种使用实验室磨损试验机（LAT）100获得橡胶经验摩擦定律的方法。LAT 100实验旨在测量各种滑移角、载荷和速度下的侧向力，随后使用ABAQUS进行有限元模拟。使用子程序（UFRIC）来实现摩擦定律，该子程序基于相应节点处的接触压力和滑动速度来计算接触片上每个节点处的摩擦系数。摩擦定律的系数μ=a+b×e−1/（αp）+c×e−2/（βv）已经通过使用一系列模拟来估计，同时最小化了实验和模拟侧向力之间的误差。本文所遵循的程序可用于使用LAT 100侧向力实验拟合橡胶的摩擦模型。

Friction Law for Rubber from Laboratory Abrasion Tester

This paper aims to devise a method to obtain an empirical friction law for rubber using the Laboratory Abrasion Tester (LAT) 100. The LAT 100 experiments, which aim to measure the side force at various slip angles, loads, and speeds, are carried out, followed by finite element simulation using ABAQUS. A friction law is implemented using a subroutine (UFRIC), which calculates the friction coefficient at each node on the contact patch based on contact pressure and slip velocity at the corresponding node. Coefficients of the frictional law, μ = a + b × e−1/(αp) + c × e−1/(βv), have been estimated by using a series of simulations along with minimizing the error between experiment and simulation side forces. The procedure followed in this paper can be used to fit friction models for rubber using LAT 100 side force experiments.

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.
