Abstract
Introduction. The purpose of the article is to consider the effect of damping in the shock absorber on smooth running, continuous rolling of the wheel and energy loss in the suspension of the car.
Materials and methods. The review is based on the analysis of the amplitude-frequency characteristics of a two-mass car model and the dependence of the shock absorber operation during the oscillation cycle on the frequency of kinematic action.
Results. The article presents a calculation scheme and equations of dynamics of a two-mass oscillatory system equivalent to an automobile suspension. The frequencies at which the amplitude-frequency characteristics intersect for different levels of damping (invariant points) in a two-mass oscillatory system are calculated. The relative operation of the shock absorber for the oscillation cycle concept is proposed and a formula for calculating the relative operation of the shock absorber in a two-mass oscillatory system is given. A comparative analysis of graphs characterizing smooth running, continuous rolling of the wheel and energy losses in the suspension is carried out.
Discussion and conclusions. It is revealed that significant contradictions between these requirements arise only near the second resonance of the sprung mass, with an increase in the frequency of vibrations in the resonant zone, these contradictions are decrease.
