Suspension design by means of numerical sensitivity analysis and optimisation

The kinematic layout of suspension systems determines the wheel's motion during bounce and rebound and thus, has a high influence on the dynamic performance of the vehicle. The presented study uses design of experiments (DoE) to determine dependencies between the location of the mounting points of the suspension devices and typical suspension indicators. Therefore, multibody systems (MBS) models of a McPherson front as well as a multi–link rear suspension are considered. Then the locations of the mountings are varied by means of numerical optimisation by considering target values for chosen suspension indicators. While vehicle handling properties are usually anticipated by regarding suspension indicators, this paper aims to present a shortcut between the positioning of a suspension's mounting points and the resulting consequences on the vehicle handling characteristics by means of DoE. Therefore, a virtual full vehicle model is introduced.
