DESIGN AND ANALYSIS OF SPROCKET FOR FORMULA STUDENT VEHICLE

Abstract

In a Formula student vehicle, the sprocket is one of the important components in the chain drive which transmits power from the engine output shaft to the drive shaft. To ensure efficient power transmission, sprocket should be designed and manufactured properly. In this study the driven sprocket of the formula student vehicle has been designed in Solid works and analysed using FEA. ANSYS software has been used to perform Static analysis to calculate the stresses induced and deformations in the sprocket. And then the Fatigue analysis has been done to determine the Fatigue life and damage. The sprocket is then optimized for weight reduction and re-analysed in ANSYS for safety and reliability. Chain sprocket is one of the most important parts used in transmitting power from the engine to the drive shafts. This study mainly deals with the design and analysis of rear sprocket of a Formula Student car. This sprocket is designed such that it is light in weight and functions efficiently. The type of chain used is roller type chain. The main challenge faced is determining the proper material and number of teeth for chain sprocket. Many iterations were carried mathematically to determine the total number of teeth and final drive ratio. The CAD model was created in SolidWorks and Finite Element Analysis was carried out in ANSYS Static Structural module. Initially a solid sprocket was created without any slots for different materials and Static structural analysis was performed. For doing static analysis, the forces and torques acting on the teeth of sprocket were calculated. Boundary conditions
