Influence of three-body particles on time-varying characteristics of tire braking friction force
In order to explore the effects of three-body particles on the time-varying characteristics of braking friction between tire materials and hard road surfaces,a three-body friction testing machine with a spring-metal slider-rubber conveyor belt structure was designed to analyze the time and frequency domain characteristics of friction between slider and conveyor belt under different loads and speeds.Results show that friction is more stable at higher belt speed.At low speed and low load,the intervention of three-body particles will cause the friction signal frequency domain to be distributed in the low frequency region,and the surface roughness of the slider affected by the particles will increase significantly after the friction behavior.This study can provide ref-erence for tire-road braking force prediction under the influence of three-body particles.
