Evaluation functioning of the agricultural units for dynamic criteria

Abstract

In the article the analysis of the causes additional energy losses in the mode sustainable movement of wheeled vehicles. The specified mode is accompanied by longitudinal linear acceleration, which causing fluctuations linear speed machine on their average. Proposed to consider sustainable movement MTU as a sequence of acceleration and deceleration. Analysis the direction of vector of complete acceleration suggests that any deviation of this vector from the axis of ordinates applicant cause harmful work and loss of energy. Depending on the sign of the projection, the work along direction of movement is an additional loss of energy, and at the same time a condition of dynamic equilibrium. The condition of dynamic equilibrium is equal modulo of negative and positive projections of the vector on the x-axis.
