MODELING, SIMULATION AND SENSITIVE ANALYZING OF THE TERRAIN VEHICLE SUSPENSION SYSTEM.

Effective method for analyzing of the terrain vehicle suspension performance is presented. The key objective of this approach is to make quick analyses of the vehicle suspension system performance. The vehicle is simplified by mathematical modeling of a quarter of it and equations of motion are solved by using Matlab software. To verify the reliability of the proposed method a comparison with one of the simply commercial software is done. The usefulness of the proposed method on the real terrain vehicle is presented in order to analyze the sensitivity of the several suspension parameters such as spring stiffness coefficient, damping coefficient, tire stiffness coefficient, sprung and un-sprung masses. The sensitivity of the suspension parameters is determined by considering of the vehicle body acceleration, vertical tire force and suspension travel that directly influences on the driving comfort and driving safety.
