Abstract


Purpose. One of the priority areas for improving the transportation process by railway transport is to increase its energy efficiency. Preliminary quantitative assessment of the resistance of the creep forces wagon, determination of the influence of damping on the amount of power resistance force at the resonance modes. Methododology. The study was conducted using mathematical modeling software system MEDYNA and an analytical method. Findings Energy consumption for overcoming resistance from forces creeps up a significant portion of total energy consumption to overcome the resistance movement, the resonance modes is a sharp increase in power consumption; its value significantly affects the value of damping. Originality. It is found that energy consumption in order to overcome the resistance of the power creeps up is a significant portion of total energy consumption to overcome the resistance movement, especially in the resonant modes. Practical value. The results can also be applied for development of a mathematical model of the car and the methodology for assessment of the resistance to motion that taking into account the resistance of the creep forces and the dissipation of energy in the environment as a hanging.
