Brake rigging dynamic simulation under braking on a track section with irregularities (the case of a passenger car)

Introduction. The paper considers simulation of the dynamic processes of the brake rigging of a passenger car under braking on a track section with irregularities. The work objectives include the development of a “rigging brakeblock -wheel working surface” contact module in a full-scale computer model of a passenger car in the “Universal Mechanism” software package; and a computer simulation of the braking operating mode from 50 to 32 km/h considering vertical and horizontal track rail irregularities for determining the mechanism of variation of the longitudinal acceleration of the brakeblock and its angular acceleration. The subject of the study is the force interaction of the elements and dynamic processes in the brake system of passenger cars.Materials and Methods. A new “rigging brakeblock - wheel working surface” contact module, which provides the determination of the longitudinal and angular accelerations of the brake rigging of a passenger car, is proposed to the “Universal Mechanism” software package,...
