AN ACTIVE SELF-TUNING SUSPENION SYSTEM TO IMPROVE DRIVER COMFORT

Abstract

This paper presents the simulation of two dimension a half-vehicle self –tuning active suspensionsystem to simultaneously improve vehicle ride comfort. A validated 4-DOF of vehicle linear modelwas used to study the performance of passive suspension system and compared with the developedactive suspension system. The governing equations of motion for the self- tuning active suspensionwas derived and used to reduce the effect of disturbances to the dynamics performance of thevehicle, which appear when the vehicle excited by a semi-circular sinusoidal bump road of a (0.1m) height. The performance of passive suspension and the self-tuning active suspension aredemonstrated by simulations and specially the vertical acceleration and the vertical root meansquare (RMS) acceleration to observe the effect of the proposed system to the ride comfort. Theactive suspension system introduced in this work show good results for improving the ride comfort
