ABSTRACT
The aim of this paper is to determine the differences in designed and manufactured model of a suspension. A set of key parameters will be compared including camber and toe in angles and their change w.r.t wheel travel as well as motion ratio. It will also focus at possibility of accurately determining the suspension system kinematics using affordable measuring devices available at the market. First, the design process main goals and project assumptions will be briefly described. Next, the CAD model and manufacturing process will be presented. Finally, the measurements of both computer and real model will be performed. The obtained results were compared and a significant difference between models has been observed. The reason of such variation couldn’t be determined unambiguously as there were numerous factors that could potentially influence the results. Also, it has been proven that accurate determination of kinematics is impossible using the given set of measuring devices.
