ABSTRACT
In this article an attempt to diagnose damage to the shock absorbers of a passenger car during road operation with the use of vibration response measurement has been described. Accelerometers were mounted on the body – sprung mass. Based on the recorded signals, FFT and Cross-Spectrum graphs were prepared. The test was performed for several variants shock absorber damage. The single-number index of vibration amplitude increase, in the range of resonance frequency, was calculated, based on spectrum analysis. The results are shown as graphs and tables, for different damage types. The realization of measurement and adopted method of damage diagnosis are described
