Abstract

The paper is concerned with a mathematical model of the Semi-Active Suspension system (SAS) of a vehicle equipped with the magnetorheological rotary brake manufactured by the Lord Corporation. SAS is a laboratory system animating the suspension action of a car quarter. A simulation model written in the MATLAB/Simulink environment is shown. The parameters of the mathematical model are identified by optimization procedures based on experimental data collected in the real-time. The mathematical model is verified. It means that appropriate system trajectories of SAS and the simulation model are compared.
