Abstract
The work is devoted to the problem of a complex study of variations in the power, kinematic and energy parameters of a hydrostatic mechanical transmission "with a differential at output" during its operation in traction and transport ranges of diesel mine locomotive running. Values of the basic transmission parameters, namely the maximum speed of the diesel-electric locomotive, the maximum angular velocity of the shaft of a hydraulic motor and a hydraulic pump, the maximum value of the transmission efficiency, and the maximum working pressure drop in the hydrostatic transmission, are obtained by the solution of a set of the algebraic equations. A peculiarity of the static model under consideration is that the calculation is carried out using the two values of angular velocities of shafts of hydraulic machines and the current and preceding working pressure drops in the transmission, resulting in an accurate determination of all of the kinematic, power and energy parameters of the transmission. Each parameter is determined until the value of the parameter under consideration at the preceding iteration becomes equal to the current value. The results obtained will be used in the determination of the reference data to simulate breaking the diesel mine locomotive
