Type: article
Abstract: The paper touches upon the issues of modelling the traction force control of the “PE-2M” industrial electric locomotive in various brake modes to ensure freight train safety and to avoid train accidents. Purpose: To analyse the prerequisites for creating a mathematical model determining the conditions for ensuring the safety of the transportation process in terms of preventing the uncoupling of automatically coupled traction units and dump cars and avoiding the car “crowding” (a car being squeezed out) described in [1]. Methodology: A mathematical model was proposed that describes the external forces have an impact on the traction units and motor dump cars. Methods: It is proposed to simulate and describe how traction and braking forces work in different motion modes. Practical significance: Calculating the arising forces when operating heavy-duty traction units is a valid method for preventing crashes.
