description: The Wentworth Institute of Technology (WIT) Society of Automotive Engineers (SAE) is a club dedicated to the design and production of single seater buggies, known as SAE BAJA cars. Every year the team builds a buggy and attends a national competition to go head to head with other schools from around the world. Due to the global pandemic however, we were reduced to only design and documentation. Our team was responsible for the Rear Suspension analysis and design, with tasks including re-examination of prior designs, the creation of design tools and simulators, research, and decision-making documentation. Theoretical designs were contemplated on paper and in discussions with the other seniors and our class advisors. Detailed kinematic simulations of the suspension system and associated purchased parts were developed using Excel. Multiple iterations of various configurations were analyzed using the Excel simulations and once the desired characteristics were obtained, the data was used to create 3-D models thru SolidWorks Computer Aided Design (CAD) for a visual representation. Starting the design in Excel, where the desired conditions can be iterated and simulated rapidly, greatly reduces the overall development time. Detailed reference material and step-by-step user guides for the Excel simulations have been developed to create a strong foundation for future generations of the club to continue competition success on and off the track.
