To a problem on a nonholonomic constraint in a drive of a beater drum of the grain combine in an acceleration conditionIn paper the equations of a nonholonomic constraint of the second order which exhibits the properties at turning on lenix a flexible drive in a drive of a thrasher of the grain combine are gained. For a justification of type of a nonholonomic constraint the oscillogram of real processes of acceleration of a thrasher is used. It is displayed, that the accepted schematization of real process of turning on lenixtransmissions incidentally differs from it. Three phases of operation lenixtransmissions are selected at turning on and for each phase constraint equations are gained. The generalised constraint equation merges all three phases of operation and is a nonlinear nonholonomic constraint of the second order. Outputs contain assay values of the gained differential equation on integrability and confirm, that connection is nonlinear to nonholonomic the second order. article [zip  67Kb]
