Design, Analysis and Fabrication of Ecokart Chassis Frame

The project is about designing, analysis and fabrication of chassis according to the specifications prescribed in Eco-kart 18 rule book. The go-kart is a small four wheeled vehicles without any suspensions and differential which is light in weight and is used for racing. The project is intended to percolate the dynamic analysis of go-kart chassis which is of cobbled with circular beams. Modeling operation is performed in SOLIDWORKS and analysis procedure is performed in ANSYS. The analysis is done on static and dynamic loading, deformation and impact on the frame. The go-kart chassis is different from general car chassis as it uses less material for chassis construction and it should be able to withstand loads applied on it. Hence strength and light weight are the basis considerations for a good go-kart chassis material. By taking all the above considerations, the suitable material is Carbon-steel ASTM A106 grade-B, the carbon-steel has – high tensile strength, high machinability and offers good balance of toughness and ductility. Hence, the chassis is fabricated by bending, cutting and welding the cylindrical beams into the required dimensions and specifications taken into consideration according to the norms given by the Society of Automobile Engineering (SAE-India) for Eco-kart 18.
