The aim of this paper is to design a new recumbent bicycle frame for the World Human Powered Speed Challenge (WHPSC) through analyses and optimizations which are conducted with the finite element solver Optistruct. The goal of the WHPSC is to set a new land speed record for vehicles that rely on human power alone. The frame proposed in this thesis will be completely new and will have the objective of halving the mass and increasing the stiffness compared to a previous frame (Taurus by the Team Policumbent), yet using the same type of carbon fibers and the same fiber volume fraction of the composite material as in that prototype.
