Abstract
The paper presents an analytical solution to the equation of dynamic energy spending for rectilinear uniform rousset of a drive wheel with an elastic tire when driving on a solid support surface. To that end, the paper proposes different initial calculation charts to analyze the dynamics of the drive wheel; it also finds the efficiency and the additional energy spending in wheel rousset.
Highlights
Various approaches and different resulting calculation charts are used when studying car wheels
A car wheel that interacts with the support surface is exposed to forces that keep it on the road, move it, stop it, or cause it to change the direction
2 Research goal and statement of problem The research goal consists in finding the dynamic energy spending for rectilinear uniform motion of a drive wheel with an elastic tire when driving on a solid support surface
Summary
Various approaches and different resulting calculation charts are used when studying car wheels. The dynamic radius rrд is smaller than the free radiusrrсв, which means an increase in traction force and decrease in the linear velocity VVaa as the tire is increasingly deformed when exposed to the increasing force Pz. The kinematic radius rrkk can be found by indirect management provided the known values VVaa and ωωkk from the equation (2). Both the dynamic radius rrд and the kinematic radius rrkk of a wheel depend on the deformation and the slippage of the tire in the wheel-to-road contact patch and can be used to find the efficiency of the wheel. Since Px = | Rx |, what makes the above force balance equation (5) different from the equation (2) is the use of the radius rrkk instead of rrд This is not an option, as the equation (5) is a dynamic rather than kinematic equation. It is necessary to refine the force balance equation (1) and the power balance equation (2) for the drive wheel with due account of losses caused by tire yielding
