Khitcenko N. Grounding of parameters of transverse cutting head feed system of road-header.

The object is a transverse cutting head feed system of road-header. The aim is to increase the productivity of road-headers with transverse cutting heads by the way of a choice of rational parameters of a cutting head feed system. Methods of researches: the system approach with use of modern theoretical methods (theory of probabilities and mathematical statistics, theoretical mechanics, analytical geometry, mathematical simulation), experimental method of strain measurements. A quantitative estimation of influence on efficiency of destruction of a heading by a transverse cutting heads in conditions of Donbass (Ukraine) of a range and character of change of feed speed is theoretically (first) received and the resource to increase in 1,5 times the productivity on unit of the established power of a cutting drive gear is proved. Probability of formation of repeated blocked cuts on picks of a transverse cutting head is (first) theoretically established and the conditions of this are analytically described.The mathematical model of optimization of parameters of transverse cutting head feed system is developed. Taken results are used at creation and modernization of road-headers P-110, P-220, KPD. Sphere of use: the enterprises of mining machinery manufacturing, scientific researches and educational process.
