Design of a tricycle chassis using computer-aided design and finite element analysis

Finite element analysis and computer-aided design are powerful tools for modeling complex systems and their responses to external stimuli. This paper explores how these techniques were employed in a highly iterative design process to improve the rear chassis of a pedal-powered tricycle. The tricycle, which is used in Lagos, Nigeria to collect and transport waste materials, is regularly ridden on rough terrain with loads greater than 600 pounds, and thus requires a frame that can be subjected to large loads without failure. The design process resulted in a chassis frame that is stiffer and has a higher safety factor than previous designs, but can still be made from low cost, locally sourced parts.
