The document addresses the process of designing the suspension of the 9th formula student car with label SE9 developed by team Superior Engineering. First, an analysis of tire data was carried out, based on which the suspension and steering kinematics were designed in the Optimum Kinematics software. This was followed by the design and dimensioning of individual components using structural analyses in the Ansys Mechanical environment. A compliance measurement of the suspension and a steering torque measurement were also performed using strain gauge force sensors. During the measurements, the Dewesoft Minitaur data aquisition system was used.
The main focus during the design process was to ensure the best possible mechanical grip of the tires, reduce the mass of the suspension, and ensure reliable functioning and adequate adjustability of parameters. It was also necessary to implement modifications for a new four-wheel-drive system, which placed particular emphasis on the longitudinal mass distribution of the race car. The starting point, or basis for the design, was the previous iteration of the race car with label J3B4-8 developed by Superior Engineering team.
