Abstract
The paper analyses the existing methods of energy recovery of vehicle suspension oscillation damping. It reveals the most preferred method in which an electromagnetic device of rotational type with a ball screw gear is used. The influence of the road parameters on the dynamic loads in the drive of an electromechanical generator is determined by mathematical modelling.
Highlights
This expression is used to determine the relative damping coefficient of γ oscillations from the results of experimental studies of the oscillations of the sprung mass
Where Wi – the amount of mechanical energy transferred to heat energy in one oscillation period; Wi – potential energy of the system when the maximum amplitude of oscillations is reached
The amount of dissipated energy at a given attenuation rate D = 2.57 and the relative attenuation coefficient γ = 0.3 relative to the LADA GRANTA car for front and rear suspension shock absorbers 98% of the energy stored by the oscillating system will be transferred to heat for one full swing and the amplitude decreases by 6.59 times
Summary
This expression is used to determine the relative damping coefficient of γ oscillations from the results of experimental studies of the oscillations of the sprung mass.
