Influence of Shock-Absorber Parameters on Vehicle Vibrations During Braking

摘要

The main goals of the work are to define consistent patterns of impacts exercised by vibration of the vehicle in emergency braking on the vehicle's movement mode and on the braking distance and to analyze the formation of oscillation. Besides, it is aimed to extend expert's opportunities for modeling vehicle movement for investigation of accidents' circumstances related to vehicle braking with the aid of the developed models. A mathematical model of impact exercised by bumper's characteristics on the vehicle's braking process has been designed, enabling the determination of coefficients of longitudinal relative forces of the vehicle's front and rear axles, which depend on the road's pavement and its condition. The obtained research results extend the vehicle vibration theory in transitional movement modes, which are used in the design and improvement of vehicle suspensions, as well as in traffic accident's investigation and improvement of methodology of their expertise calculations.
