Validation of Key Parameters Between Real and Computer Model of Suspension System Used in FSAE Vehicle

摘要

The aim of this paper was to determine the differences in the designed and manufactured model of a suspension.A set of key parameters was compared, including camber and toe in angles and their change w.r.t wheel travel, aswell as the motion ratio. It also focused on the possibility of accurately determining the suspension system kine-matics using affordable measuring devices available on the market. First, the design process, main goals and proj-ect assumptions were briefly described. Next, the CAD model and manufacturing process was presented. Finally,the measurements of both computer and real model were performed. The obtained results were compared and asignificant difference between models was observed. The reason of such variation could not be determined unam-biguously, as there were numerous factors that could potentially influence the results. Moreover, it was proven thataccurate determination of kinematics is impossible using the given set of measuring devices.
