Generation Mechanism Analysis and Calculation Method of Loader
Parasitic Power Based on Tire Radius Difference 2022-01-5102
The powers generated by the skidding and slipping of a vehicle in unit time
during driving are referred to as parasitic power. It has significant effects on
wear on the tires, service life, and overall efficiency. However, existing
methods to calculate parasitic power expressions that are not solvable in some
cases, the reasonableness of the results of their calculations cannot be
verified by experiments and the parameters of the loader cannot be calculated
during the design of the vehicle. In this paper, we systematically analyze the
mechanism of generation of parasitic power based on the differences in the radii
of the tires of loaders. We innovatively propose a theoretical calculation
method to calculate the wheel circumference parasitic work during the design of
the loader. The results of experiments show that errors between the theoretical
and experimental values of the wheel circumference parasitic work calculated
under various working conditions were smaller than 5%.
