Simulation of efficient power installation of wheeled dumper

as a result of the development of an electric drive for a vehicle, a number of the following problems arise, namely: 1) variable load indicators during the operation of the vehicle; 2) numerous starts and stops of the traction electric motor, resulting in enormous energy costs; 3) resulting reverse during engine operation. The main purpose of this study is to design an electric drive for the vehicle in terms of efficiency, environmental friendliness and economy. Calculation of the electric motor power was performed in accordance with the technical characteristics of the vehicle. Power-velocity dependencies are obtained using different acceleration values. Based on the obtained design power of the electric motor, the corresponding model was selected. A simulation mathematical model of the electric drive was compiled in the «Matlab Simulink» software system, a detailed description of model units is presented, transient diagrams are obtained that reflect the effectiveness of the developed electric drive. The energy storage was calculated, a suitable model was selected, based on the analysis of the batteries. As a result, the simulation mathematical model of the electric drive for the vehicle was developed, in which the input parameters (current, voltage, speed) can be changed.
