Energy Analysis of Vehicle Suspension Oscillation Cycle

This article is devoted to conducting the energy analysis of the oscillation cycle in vehicle suspension based on the research of the dynamics equations of the linear single-support single-mass vibrating system with fixed elastic and damping characteristics at harmonic kinematic disturbance. The characteristics of the relative energy flows in the oscillation cycle of the suspension, taking into account the shock absorber inefficient work are received. The physical meaning of the overall characteristic point to the series of the sprung mass amplitude-frequency characteristics is identified. Analysis of vibration isolation properties of the suspension on the sprung mass amplitude-frequency characteristics and the frequency characteristics of the total width of the suspension ineffective work areas in the oscillation cycle is carried out in the damping regulation on the inefficient work areas and on different damping levels.
