摘要
Automobile exploitation parameters can be determined in two basic ways performing experimental research or analytical calculations. Analytical calculations are cheaper but not always as exact as experimental data. Within the frame of the research a mathematical model has been developed for determination of such automobile exploitation parameters as the speed of movement, characteristics of traction, distribution of power in the kinds of resistance, dynamic factor, run-up acceleration and run-up time. Original methods have been developed for determination of the run-up time if the acceleration is known at which graphic integration is not applied. The capacity for work of the model is approbated with data of actual automobiles and they are compared to the theoretically obtained data.
