Effectiveness Of Mashine And Tractor Units Functioning

• Presnyakov V.A.

Some questions of effectiveness of machine and tractor units functioning and mathematical model of these units are examined. The author analyzes the lateral vibrations of technological unit and comes to the conclusion that these vibrations make essential impact on the quality of its work. The car wagging is considered as the self-oscillatory process depending on a number of factors: uniformities of a surface, constructive features of the car, the mechanical way of its combination with tractor, etc. Differential equations of a horizontal lateral vibrations and the scheme of forces appearing in the course of uncontrollable turning movement are presented. The formula for calculation of critical speed of the technological unit movement is offered.
