Rebrov A. Influence of link structure of caterpillar track of crawler on transmission loads and soil pressure

The object of the study: process of the interaction of soil, caterpillar propulsor, frame and transmission of tractor T-150 in unit with outboard and half outboard plow when moving in formed mode. The purpose of the study: determination of the regularities dynamic loading of transmission and pressures on soil, motivation of the choice of rational constructive parameter of caterpillar propulsor. The methods of the study: analytical methods at calculation kinematical and power features of the dynamic system, numeric methods of the decision of the systems of the differential equations of the moving the component parts of the system and experimental methods of the studies on base tensormetry and vibrometry. Theoretical and practical results: is motivated need of the account link structure of caterpillar chain, way of aggregation, surrounding ambiences factor at analysis of the loads of the tractor and it influences on soil; rational design caterpillar propulsor is determined on base of the comparative experiment. Novelty: it is received new regularities of the influence caterpillar propulsor configuration on transmission loads and pressure on soil; it is deturmined the features of the interaction of soil, caterpillar propulsor and transmission for different configurations of caterpillar propulsor with taking into account the link structure of caterpillar chain. The degree of the introduction: it is introduced in the manner of recommendation at the option to rational design of caterpillar propulsor and is accepted to use on Kharkiv tractor plant. The branch of the use: tractor building.
