摘要

本文对干滑动摩擦条件下记录的声级进行了分析。放置在销上的直径为6毫米的球由100Cr6钢、碳化硅(SiC)和刚玉(Al2O3)制成，而高度为6毫米、直径为42毫米的旋转盘由100Cr6钢制成。每个针盘系统测试两种空气相对湿度值(50±5%和90±5%)。利用回归树和随机森林建立了a声级模型。本文对所得模型的精度进行了分析。还对根据声级描述符进行的六项试验进行了分类。

CLASSIFICATION AND MODELLING OF SOUND EMISSION SIGNALS IN SELECTED TRIBOSYSTEMS

The paper presents an analysis of the sound level recorded during dry sliding friction conditions. Balls with a diameter of 6 mm placed on pins were made of 100Cr6 steel, silicon carbide (SiC), and corundum (Al2O3), while rotating discs with a height of 6 mm and a diameter of 42 mm were made of 100Cr6 steel. Each pin and disc system was tested for two values of the relative humidity of the air (50 ± 5% and 90 ± 5%). Models of the A-sound level were developed using regression trees and random forest. The paper presents an analysis of the accuracy of the models obtained. Classifications of the six tests performed on the basis of sound level descriptors were also carried out.
