APPLICATION OF SIMULATED ANNEALING ALGORITHM (SA) FOR DESIGN OPTIMIZATION OF AUTOMOBILE SUSPENSION SYSTEM

摘要

In this paper optimization technique, Simulate annealing Algorithm(SA) is studied & applied to optimize Suspension system of automobile. Suspension system is collection of springs & dampers. Selection of values of stiffness of the spring & damping values of dampers is the important task, because ride comfort of the driver is depend on this. This selection is done here with the help of SA. Programming has been developed in MATLAB 7.5, in which the steps of SA are followed to get the output as a seat acceleration, which is measure of ride, with input values of stiffness & damping constants. Principle behind optimization by SA is a naturally serial algorithm, but its behaviour can be controlled by the cooling schedule. Convergence of this method has been plotted with no. of generations.
