Abstract

The results of a study of the noise generating mechanism during the application of disk brakes on rolling stock are presented. It is shown that one of the main sources of noise generation is the deformation of the microgeometry of the surface layer and its elastic recovery, which occurs under the influence of the interaction of the working elements of the disk brake. The influence of the ratio of the working areas of the friction elements that model the brake pad and brake disc on the noise intensity during their interaction is estimated. A design and technical method is proposed for reducing the noise level of a disk brake during braking, which consists of increasing the ratio between the working areas of the brake pad and brake disc.

盘式制动器在车辆上应用过程中的噪声产生机理

摘要

介绍了盘式制动器在机车车辆上应用过程中产生噪声的机理的研究结果。结果表明，产生噪声的主要来源之一是表层微观几何形状的变形及其弹性恢复，这种变形是在盘式制动器工作元件相互作用的影响下发生的。估算了建模制动衬块和制动盘的摩擦元件的工作区域之比对它们相互作用期间的噪声强度的影响。为了降低盘式制动器在制动过程中的噪音水平，提出了一种设计和技术方法，该方法和技术方法包括增加制动衬块和制动盘的工作区域之间的比率。
