Automobile suspension has moving structural elements interconnected by elastic links. Oscillatory processes in the suspension of a vehicle occur when the wheels interact with the road. Depending on the speed of the vehicle, the frequency of vertical vibrations of the moving masses of the suspension also changes. Any mechanical system containing moving masses interconnected by elastic components has its own oscillation frequency. The phenomenon of resonance in the suspension of the vehicle occurs, when the frequency of external influences becomes equal to the natural frequency of vibrations. When the frequency of external sources becomes equal to the frequency of natural oscillations, a resonance phenomenon occurs. At resonance, the amplitude of oscillations increases sharply, which in turn causes vibration throughout vehicle’s body. This leads to a sharp increase in dynamic loads, which can lead to structural failure due to metal fatigue. The rigidity of the road tyre has a great influence on the oscillatory processes in the suspension of an automobile as it forms a single elastic system in conjunction with other elastic elements. To study resonance phenomena, a mathematical model of an automobile suspension has been developed. Based on the results of the numerical model, it has been determined that the structural resonance occurs at certain speeds. A method for dynamic damping of vehicle suspension vibrations at resonance is proposed. The effect of the road tyre stiffness and viscous friction in the shock absorber on the dynamic loads acting on the suspension elements has been established. For the vehicle suspension, the parameters of the dynamic vibration damper are determined.
