Abstract：To investigate the effect of three-body particle invasion on the friction noise of friction pairs,a friction testing machine for the test research was constructed.Data was collected through a noise acquisition analyzer,and the impact of three-body particles on the friction noise of the disc block friction pair was analyzed.Simultaneously the friction force signal of the friction pair was collected to explore whether there is an inherent relation between the friction force and friction noise of the friction testing machine under frictional parameters(such as speed and pressure).The test results show that under different pressures,the friction noise first increases and then decreases with the increase of rotational speed.After the invasion of three-body particles,the friction noise significantly increases,but the overall trend is consistent with that of two-body friction.Friction noise is directly proportional to friction force.Certain reference value for the analysis of the noise characteristics of braking systems under the invasion of three-body particles is supplied.
