Abstract

The paper presents the results of investigations of a railway disc brake system related to the mass wear of its brake pads. The tests were carried out on a certified brake stand designed to determine the friction-mechanical characteristics of the brakes. The test stand was additionally equipped with a thermographic camera to observe the contact points of the brake pads with the disc. Particular attention was drawn to investigating the impact on the mass wear of the brake pads of such parameters of the braking process as contact surface of the brake pad with the rotor, thickness of the brake pads as the indicator of their initial wear, clamping force of the pads against the rotor, rail vehicle mass to be decelerated, and speed, at which the deceleration begins. The scientific aim of the paper is to present the relations between the mass wear of the brake pads and the quantities that characterize the braking process. A regression model was determined to estimate the wear of the brake pads based on a single braking process with the preset input quantities.

基于试验台摩擦力学研究的刹车片磨损建模新方法

本文介绍了铁路盘式制动系统刹车片大量磨损的研究结果。测试是在经过认证的制动支架上进行的，旨在确定制动器的摩擦机械特性。试验台还配备了热像仪来观察刹车片与制动盘的接触点。重点研究了制动过程中刹车片与转子的接触面、指示刹车片初始磨损的厚度、刹车片对转子的夹持力、待减速轨道车辆的质量、开始减速时的速度等参数对刹车片质量磨损的影响。本文的科学目的是提出刹车片的质量磨损与表征制动过程的量之间的关系。在给定输入量的情况下，建立了单次制动过程中刹车片磨损的回归模型。
