Design and development of quad bike chassis frame

Safety is found to be the most critical concern about a quad bike designed especially for wider varieties of terrains available and offers negligible protection to the rider. A higher number of deaths and injuries have been reported to all-terrain vehicles (ATV) according to the National Trauma Data Bank. This inspires our team to design a quad bike for the safety of passengers. In this work, a quad bike chassis frame is designed and developed for quad bike design challenge (QBDC). The present development is based on the principle of similitude, personal experience, actual test track data, and all previous history to optimise the design of the quad bike chassis frame. Structural analysis of the designed frame is carried out using finite element analysis (FEA), and modal analysis is performed through FFT. Results acquired indicate that the developed chassis frame is rigid, lightweight, and safer compared to the old frame. This original contribution shows a systematic way of design for the safety of quad bike occupants.
