Abstract

This article presents a laboratory device by which the course of two signals can be detected using two types of sensors-strain gauges and the DEWESoft DS-NET measuring apparatus. The values of the coefficient of friction of the brake lining when moving against the rotating shell of the brake drum were determined from the physical quantities sensed by tensometric sensors and transformed into electrical quantities. The friction coefficient of the brake lining on the circumference of the rotating brake disc shell can be calculated from the known values measured by the sensors, the design dimensions of the brake, and the revolutions of the rotating parts system. The values of the friction coefficient were measured during brake lining movement. A woven asbestos-free material, Beral 1126, which contained brass fibers and resin additives, showed slightly higher values when rotating at previously tested speeds compared to the friction coefficient values obtained when the brake drum rotation was uniformly delayed. The methodology for determining the friction coefficient of the brake lining allowed the laboratory device to verify its magnitude for different friction materials under various operating conditions.

摘要

本文介绍了一种实验室装置，利用应变片和DEWESoft DS-NET测量仪器这两种传感器来检测两个信号的变化过程。通过张力传感器感知物理量并将其转换为电量，从而确定制动衬片与制动鼓旋转外壳相对运动时的摩擦系数值。根据传感器测量的已知值、制动器的设计尺寸以及旋转部件系统的转速，可以计算出旋转制动盘外壳圆周上制动衬片的摩擦系数。在制动衬片运动过程中测量了摩擦系数值。一种不含石棉的编织材料Beral 1126，含有黄铜纤维和树脂添加剂，与制动鼓旋转匀速减速时获得的摩擦系数值相比，在先前测试的速度下旋转时显示出略高的值。确定制动衬片摩擦系数的方法使该实验室装置能够在各种运行条件下验证不同摩擦材料的摩擦系数大小。
