Abstract: Chassis is the basic and most important component or sub system which assimilates as a structure for various vehicles. It serves in giving the structural safety and also for embedding various systems like steering, powertrain, suspension and braking system on to it, thus having a dual purpose. This makes the chassis the robust and most cautious component to design, especially in race cars like go- kart. Keeping in mind the weight aspect of vehicle and its effect on performance of kart and considering the maximum safety the kart was designed. To satisfy all these criteria it is very crucial to keep in mind various parameters like material selection, cross-section of tubes, forces developed during impacts that might occur on track. Through this study, we aimed to design and analyze the chassis so as to achieve high strength to weight ratio. With the help CAD modeling software CATIA V5 R21 and Ansys workbench 14.5 the model was designed, analyze and optimized to serve the purpose. Material selection was tough task and hence ample market survey was done. This process was done in designing and fabricating the Go-Kart for National kart Racing Championship (NKRC) and it proved to be efficient.
