Introducing Dual Suspension System in Road Vehicles Keywords: Primary Suspension, Secondary Suspension, Vibrations, Road Vehicles Mehran University Research Journal of Engineering & Technology Volume 32 , Issue 2 IMTIAZ HUSSAIN,JAWAID DAUDPOTO,ALI ASGHAR MEMON Abstract The main objective of suspension system is to reduce the motions of the vehicle body with respect to road disturbances. The conventional suspension systems in road vehicles use passive elements such as springs and dampers to suppress the vibrations induced by the irregularities in the road. But these conventional suspension systems can suppress vibrations to a certain limit. This paper presents a novel idea to improve the ride quality of roads vehicles without compromising vehicle?s stability. The paper proposes the use of primary and secondary suspension to suppress the vibrations more effectively |
