Design Optimization of Two Wheeler (Bike) Chassis

The chassis frame forms the backbone of a vehicle; its principal function is to safely carry the maximum load for all designed operating conditions. Automotive chassis is the main carriage system of a vehicle. The chassis serves as a skeleton upon which parts like the gearbox and engine are mounted. The two-wheeler chassis consists of a frame, suspension, wheels, and brakes. The chassis is what truly sets the overall style of the two-wheeler. Commonly used material for two-wheeler chassis is steel which is heavy in weight or more accurately in density. There are various alternate materials like aluminum alloys, titanium, carbon fiber, magnesium, etc. which are lesser in weight and provide high strength and thus can be used for chassis. This research deals with the design of a two-wheeler chassis frame and its weight optimization. Various loading conditions like static and dynamic loadings were carried out on the chassis and the design is optimized by reducing the weight of the chassis by using alternate material while maintaining the strength.
