Advancements in science and technology, effective designs and newly advanced ways of manufacturing for the need to fulfill the customer expectations and provide them with better goods have led to these developments. With the invention and help of numerous mechatronic systems, there are technological advancements in various automobile sectors and thus given better performance output. A suspension system is responsible for the safety of both the vehicle and occupants by providing stability and a comfortable ride during its maneuvers. Without the help of any suspension system, it would have made it extremely hard for a driver to control a vehicle since all the shocks and vibrations would have been directly transmitted to steering without any damping. This project aims to design and build the suspension system for the upcoming Car. To be able to design a suspension system background research was performed to understand the suspension geometry. The suspension type used will be an unequal double wishbone. The suspension system is an essential part of any vehicle. It should be reliable and compact as well as provide better handling to the car. The suspension deals with a lot of forces when cornering, acceleration, braking, and bump conditions are applied during dynamic situations. This paper presents a methodology to design and build a suspension system for a passenger car.
