Theoretical Studies of Automobile Smooth Running on High-Safety Wheels

Abstract

The tendency of scientists and engineers to enhance automobile safety led to appearance of high-safety wheels able to keep stable and steerable vehicle movement at the loss of excess air pressure even in several pneumatic tires. In case of loss of excess pressure in one of the pneumatic tires, the modern high-safety wheels producers guarantee safe non-stop vehicle running at a speed up to 80 km/h for a distance within 200 km. However, the loss of excess air pressure even in one pneumatic tire results in noticeable deterioration of factors for majority operational properties including smooth running specified by the automobile sway intensity when running on the uneven surface roads and under off-road conditions. Scientific studies aimed at the enhancement of smooth running and keeping vibration loading levels to normative limits for cars forced to continue movement without the excess air pressure in one or several pneumatic tires ensure their urgency.
