Analysis of the Double Wishbone front suspension system

Suspension system in a car connects the chassis to its wheels and it comprises of a system of springs, dampers and linkages. Independent suspension systems typically offer better handling and ride quality. This is because of the lower un-sprung weight and the capability of each wheel in addressing the road interaction independently without affected by the road interaction of the other wheels on the vehicle. In this paper, we have analyzed the Double Wishbone suspension for static conditions and studied the wheel travel over a bump and optimized the design to improve the ride quality by keeping camber and toe and under desired limitations. The suspension system of a vehicle needs to be durable, light weight, efficient and structurally stable. The paper mainly focuses on the static structural analysis of the vehicle under self-weight and the analysis of the wheel travel of the vehicle experiencing a bounce and rebound due to a bump and thereby deducing a safe limit by addressing the limitations in toe and camber angles.
