- The capacity to handle tough undulated terrain is the most important aspect of developing an All-Terrain vehicle. We get the opportunity to design and manufacture our buggy and race it against other collegiate teams throughout the country thanks to BAJA SAE. Our vehicle is designed to operate under adverse driving conditions with ease. It can endure excessive loads and impacts throughout the event. Our design has been brainstormed, debated, tested, and verified based on various Automobile literature, FEA Analysis, physical testing, and experience gained over 7 years of manufacturing ATV. This year we have prioritized driver's ergonomics and maximum utilization of space in the roll-cage. The most important aspect of designing an ATV is to make it robust and aggressive. Goals set this year were specifically targeted towards making our vehicle agile around the corners while keeping it sturdy and durable on the track. Also this year we have tried to reduce the overall weight (curb weight) of the vehicle. This year we have designed our vehicle specifically to withstand the harsh and unruly condition of the track. All the components are designed and dynamically simulated in various FEA soft-wares, like LOTUS Shark, ANSYS, Hyperworks, Solidworks, and Catia. This paper is a documentation of all the dynamic as well as the static data used for manufacturing our ATV. The roll-cage is designed to maximize the utilization of space and facilitate egression, by minimizing excessive bends; also the inclination of RRH is provided to improve the weight distribution. The RRH inclination enhanced the aspect of comfort for the driver and the height of the SIM increased to match the requirements. We have lowered the front roll axis; incremented ground clearance and narrower track width will enhance the agility of the vehicle around the corners. This vehicle's steering layout facilitates over-steer, increased length of knuckle arm minimizes driver's effort and also the material of steering arm has been optimized for weight reduction. We have removed the excessive notch from the rotor and its overall thickness has been increased to enhance the clamping force. The pedal ratio has been increased to decrease the driver's effort. In transmission, UV joints are added to the shafts to minimize the strain on the gears and we have added Gaged CVT to enhance the overall performance. The aluminum sheets for body panels have been removed by polycarbonate sheets & the mountings have been optimized.
