Abstract

This paper presents optimization of two suspension quarter car model using Design of Experiment Method. The aim is to determine suspension parameters to achieve the best comfort for human. Two models are used, which are 2 degree of freedom (2 DOF) and 3 degree of freedom (3 DOF). Sprung mass acceleration and also kinematic criteria chamber angle and toe angle had been used to validate both models. The optimization results are compared using step excitation base on the conditions from literature of optimal suspension system. In the case of 2 DOF suspension model at initial condition with optimized value from the literature, sprung mass acceleration did reduce by 32.36%, but suspension working space did increase by 18.71%. Dynamic tyre load did not show significant change which reduces by 0.02%. For 3 DOF suspension model at initial condition with optimize value from the literature, sprung mass acceleration did reduce by 32.28%, but suspension working space only increase by 0.09% and dynamic tyre load reduce only by 0.05% which did not shown significant change.
