Abstract
Damping vibrations occurring within the car’s suspension is an indispensable phenomenon in suspension operation. The most common damping element used in the suspension is the hydraulic shock absorber. Modern shock absorbers used in the suspensions mostly have nonlinear characteristics and other complex functional properties. The chapter presents research on hydraulic shock absorbers for similar conditions of their operation. The main aim of the study is to determine the forces generated in the damper due to the impact of road roughness. Thus the simulation studies were carried out on a developed dynamic model of the damper. Defined random signals were used as the input functions, which correspond to the real spectral density of road inequalities. For the proper analysis result, signal processing in the time and frequency domains was conducted. A further objective of the work is to develop guidelines for test methods for the technical conditions under normal operation of shock absorbers built into vehicles.
