Suspension damping optimization using genetic algorithms

Abstract

Vehicle ride comfort is a function of the frequency of transmitting vibrations to passengers from road irregularities. The objective of this research is to provide a systematic method into the requirement of the passive suspension based on genetic algorithm (GA). Objective function of GA method is driver’s seat acceleration to provide driver ride comfort. The passive suspension damping coefficient and driver’s seat suspension damping coefficient have been optimized. In this paper, a vehicle with eight degrees of freedom has been simulated to achieve driver’s seat comfort. Analytical results explained by mathematical equations presented in the graphical form have been included.
