The Stabilization of the Vertical Reactions of the Road on the Wheels and Ride Quality of a Vehicle

The article discusses the issue of increasing driving stability and ride quality of a vehicle when driving on a road with a periodic profile. Vehicle vibrations have an impact on virtually all the main operational properties of the vehicle (stability, control and ride quality) as well as fuel consumption. The movement of the vehicle under resonance wheel conditions can be accompanied by a weakening of the vertical reaction of the road on the wheels and even wheel detachment from the road that can decrease vehicle stability. Resonant vibrations of the vehicle body are characterized by large linear and angular displacements of the body and the vehicle payload (driver, passengers, cargo, etc.) that can lead to dangerous road situations. This manifests in adverse driving conditions, both from the point of view of stability and controllability of the vehicle, and the ride quality that determines the comfort of using the vehicle. The paper proposes a new active safety system that helps to increase the vehicle ride quality. The research results of the influence of the stabilization system of the vertical reactions of the road on the ride quality are presented.
