Sažetak
The vehicle suspension system is supposed to provide comfort to the driver and to passengers, as well as to ensure the vehicle stability, especially while driving through curves, i.e. while cornering. Simulation is frequently used to analyse the vehicle behaviour under various driving conditions. When defining a physical model of a suspension system, as the initial step in the simulation program development, it is important to determine, as precisely as possible, the following key parameters: mass, mass moments of inertia, stiffness, damping properties of the material, damping of elastic vehicle parts (stabilisers, tyres), damping properties of particular vehicle dampers, damping of joints and links as individual components of the suspension system, as well as other characteristics.
A telescopic damper is an essential part of the suspension system. Its damping properties are highly non-linear. Most publications deal with damping in general terms. Specific data is usually not provided. This paper is, however, focused on determining both the magnitude and the character of damping. A methodology that combines experiment and calculation has been developed for that purpose. As part of the experiment, kinematics (accelerations) at characteristic positions of the suspension system is first determined. By combining a one-dimensional (1D) mathematical model and experimental results, the instantaneous values of damping force and the magnitude of damping coefficient, as a function of the piston velocity and the travel of the telescopic damper, were determined. The suspension system of an in-production passenger vehicle is investigated using a combined analytical and experimental method. The results of real damping and of damping coefficients are presented.
Finally, the results of the simulation, created by using the parameters determined in the previous step, and of the experiment were compared.
