ABSTRACT

At present JSC «Russian Railways» forms a coherent policy on safety and reliability of the transportation process, with one of the most urgent is the problem of removing unwanted trees and shrubs in the right of way of railways. In accordance with the applicable instructions in the right of way is not allowed of weeds overgrowth of trees and shrubs. Removal of unwanted trees and shrubs in the right of way mechanical method can be carried out a working body (the cutting head), controlled by manipulator. The article examines the dynamic interaction between the rotor of the working body of unwanted trees and shrubs. On the basis of the actual conditions of the scheme developed by cutting shoots in which the axis of rotation of the rotor axis and are crossed overgrown, is at a distance, is given a number of dependencies. The resultant cutting force is determined taking into account the angle of the cutting speed and the angle of supply and axis deviation shoots under the influence of the tool in the direction of rotor rotation. It is shown that the height of the cut shoots continuously decreases to a certain minimum value determined in accordance with the technological map, and the value can be negative in the case of the interaction of the rotor with the soil. To ensure the effective cutting shoots without a break (to simultaneously transform it into chips the corresponding working body) is given a number of these conditions, the implementation of which depends on the physical and mechanical characteristics of the vegetation removed. Considered a dynamic interaction model rotary working member with trees and shrubs allows you to get a number of important practical recommendations for the whole system of machines having certain common properties.
