Study of the Interaction of a Transport Vehicle with an Open Road

Abstract

One of the ways to reduce the harmful effects of undercarriage of traction and transport vehicles on the ground and to improve their traction characteristics is the use of rubber-track propulsion. Experimental research have shown that the rubber-track propulsion provides a more even distribution of the specific pressures created by the traction-transport machine and reduces the peak loads on the ground compared to the metal track. When the caterpillar propulsion interacts with the ground, the force of gravity of the machine is transmitted to the ground through the propulsive support branch. The values ​​of these reactions and the patterns of their distribution over the support surface reflect the physical essence of the processes of interaction between the propulsion unit and the ground. The article presents the results of the research of the distribution of normal pressure along the length of the support surface of the rubber track. The uniform distribution of pressure affects the permeability of the traction vehicle.
