FSAE Rear Suspension Geometry Hardpoint Optimization

Optimized rear suspension hardpoints based on targeted kinematics such as roll-center migration, anti-squat, instant centers, and motion ratios.

Approach

We used suspension analysis tools along with targeted kinematic parameters from various tools and calculations to define a wireframe of our suspension geometry. This was the first step to begin chassis and part design for the rest of the team.

Methodology

With roll center, motion ratio, anti-squat, and etc. targets, we were able to iterate through point locations to meet our kinemtic targets.
