Resumen
The major part of the locomotives under operation requires increase of the maintenance and repair expenditures by 40-60% in comparison with the modern models. Creating a hybrid shunting locomotive is an effective solution to the shortage of finance and the high cost of a new locomotive fleet. It was the analysis of methods and models for determining the technical and economic parameters of hybrid vehicles, which have been developed by scientists from different countries. It was created a mathematical model to determine the optimum parameters of the motor and energy storage, depending on the operating conditions. It was calculated coefficient of technical level, life cycle and on the basis efficiency ratio is defined hybrid shunting locomotive for different operating modes, which fully confirms the efficiency of introduction this type of locomotives instead of the diesel locomotive series CHME3. Traction calculations confirm the efficiency of proposed solutions.
