| Summary: | Suspension system is one of the most important subsystems in any automobile.An ideal system serves the occupant with comfort, minimal road disturbance, and thedriver with steer control and maneuverability.In the process of developing an ideal system, all the existing suspension systemsare reviewed by Pro-con analysis method, and McPherson suspension system is drawnout as most suitable system for Uniti car, as worked out from Pugh’s decision matrix.House of Quality is built to list out and prioritize technical specifications, userrequirements/ expectations for L7e car’s suspension. Quality Function Deploymentalso helped us to evaluate competitor strengths and weaknesses. The results obtainedfrom QFD is used as database to modify the existing predesigned McPhersonsuspension template that is available in ADAMS/Car 2015.1.0. Once the system wasmodified in the way it could fit the dimensions of Uniti car, it is tested and simulatedon test rig, whose results were out in the form of graphical plots between variousimportant suspension parameters.Parallel wheel travel, Opposite wheel travel, and Brake pull analysis are thetests conducted during simulation, whose results reveals that the modified suspensionsystem works efficiently for maximum working load and is stable on road to maneuvers.
