Go – Kart
Go Kart (GK) is a type of open-wheel car which can be fabricated in all shapes and forms, from motor-less models to high powered racing machines. GK is also called as miniature of a racing car. In the present work the chassis of GK has been framed with AISI-1020 square pipe with 2mm thickness. This may be attributed to the constraint that the GK should be of suspension free, therefore the chassis material must be flexible enough to work as a suspension and stiff enough not to break or give away on a turn. The material has 380 MPa and 207 GPa as tensile strength and yield strength respectively. The GK is powered by Honda stunner 125cc engine fitted with dual disc brake. CATIA V5 software has been utilized to model and assemble the GK. The static structural analysis of the frame has been done by using ANSYS R16.2 software. Loads are calculated theoretically and applied on the frame at critical points to calculate the amount of deformation and stress generated at the time of collision. Impact tests from front, side, rear and torsion has also been done with an impact speed of 80, 65, 80 Km/hr respectively. The total deformation (in mm) in front, side and rear is found to be 0.152, 1.151 and 0.143, when 3030, 2468.18 and 3030 N load applied on respective sides. An average factor of safety of magnitude 6.93 has also maintained throughout the analysis. The applications of such vehicles are in Kart racing, amusement activities and sometimes personal transportation in some countries. The GK modelled, designed and fabricated have been participated in NKRC championship at Bhopal, Madhya Pradesh, India.
