Vehicle traction system loads simulation

The design, building and commissioning of the laboratory model for the vehicle traction system loads simulation, as well as evaluation of its function, was carried out in this research. In preparation part of this research, the theoretical analysis of vehicle in motion, considering forces, torques, power and energy of vehicle traction system, was conducted. The theoretical basis for vehicle traction system loads simulation was founded. The laboratory model concept was proposed. Due to time and financial limitations this concept was reduced to the present laboratory model. Simulation of vehicle traction system loads for real vehicle was carried out. All measurements for identification of forces, torques, drive wheel rotation speeds and vehicle velocities of vehicle in motion, for specific regimes and conditions, were conducted. Measurements of torques and drive wheels rotation speeds of the same (chosen) vehicle, under same conditions as in simulation, were carried out. All those measurements, conducted on simulation model and real vehicle, were compared and that comparison showed excellent match. The keystone of this research is "the base vehicle method" with "base mass" and "simulation factor" as key elements. Established and determined method, enables simulation of any vehicle type, regardless to its shape and mass. That enables a great flexibility in simulation procedure application for different types of vehicles with different masses. Limitations and possibilities for further research on simulation are determined.
