Abstract

The article examines the problem of ensuring the safety of motorcycle movement in the conditions of a turbulent air trail created by a large truck. The development of computer technology, software and methods of computational fluid dynamics (CFD) allows conducting theoretical studies of various aspects of the movement of motor vehicles, which are difficult to reproduce experimentally and which at the same time can have a significant impact on accidents on public roads. A motorcycle is one of the most dangerous vehicles in terms of traffic accidents with human casualties. The analysis of accidents involving motorcycles showed that most of the time their causes are insufficient skill and inability to drive a motorcycle, as well as insufficient attention. At the same time, when driving a motorcycle, movement in conditions of turbulent air flows with a sharp change in their speed and direction is a particular danger. Such conditions arise when overtaking large trucks moving at high speed. An aerodynamic model of the movement of a truck and a motorcycle was built for their different relative positions. From the position of the motorcycle in the turbulent wake behind the truck and after passing the compressed air zone in front of the truck. A study of turbulence models was conducted to assess the accuracy of the most common Reynolds-averaged Navier-Stokes models such as k–ε and k–ω. Zones in which the largest changes in air pressure occur during motorcycle movement have been established, and the magnitude of these changes has been determined. Accordingly, recommendations are provided regarding the characteristics of motorcycle movement when overtaking a large-sized truck and the safe trajectory in which such a maneuver is the safest for drivers with insufficient experience in driving a motorcycle.
