Designing a Light-Weight Child Bike Trailer

This bachelor’s thesis investigates the feasibility of designing a lightweight, aero-dynamic child bike trailer using composite materials for its main structural ele-ments. The project encompasses theoretical design, finite element analysis (FEA),and computational fluid dynamics (CFD) to optimize the structure for weight re-duction and improved aerodynamics while ensuring strength. Key considerationsinclude material selection, laminate stiffness, and manufacturing methods. Thestudy provides a plan for future prototype development. Findings suggest that acomposite-based design can significantly reduce weight and enhance aerodynamicperformance compared to traditional materials and structural design.
