文摘

The design of suspension system has been one of the challenging tasks for engineers. The main function of any suspension system is to reduce or eliminate the road excitations transmitted to vehicle body. An effort has been made in this paper for a passive suspension system by using an optimization technique called Genetic algorithm to absorb vibrations as per ISO 2631-1: 1997 standards. The spring stiffness (ks), damping coefficient (cs), sprung mass (ms), unsprung mass (mu), tyre stiffness (kt) are optimized in such a way that ride comfort is increased .The quarter car and driver seat with the driver's body are simply modeled together as four degree of freedom (DOF) system by using SIMULINK for analyzing the ride comfort.
