Anti Roll Bar Design

Please enjoy the 2-minute summary gallery below, or scroll further to explore my work in greater detail

As is readily apparent on this website, the majority of my work pertains to vehicle dynamics modeling and simulation, as well as kinematic design. My skills are not limited to computer coding and dynamic systems, however! One of my other design projects for the 2020 Clemson Formula SAE car was the anti-roll system, and on this page I'd like to walk you through the major steps in the design and development process.

Project Scope

Early on in the full vehicle design exploration, the team had decided to pursue a suspension concept with decoupled pitch and roll modes. Typical decoupled suspensions employ a bi-directional spring and damper element, which can introduce cost and complexity to develop. Other teams have worked around this by implementing two roll units, one which actuates in either roll direction, but this is a heavier and larger solution. We decided to use an anti-roll bar (ARB) for the relative simplicity, packaging freedom, and cost to develop. As a bonus, shifting the ARB pickup points to the pitch rockers enabled us to minimize torsion loads across the actuation axes, minimizing weight and compliance.

Moving forward, I created a list of constraints and criteria to guide the project and design direction. The static roll stiffness targets were calculated from target roll gradient and roll center locations which had already been finalized by that point.
