Abstract

Due to robustness, low cost and high reliability, leaf springs are still widely used as suspension components for heavy commercial vehicles. The leaf spring in this field of application has to meet two demands: suspension of the vehicle and support of the axle. The deformation of the leaf spring has an influence on the axle kinematics and as a result on the dynamics of the whole vehicle [1]. Therefore this deformation has to be taken into account.
Commercial MBS software packages provide a model approach using beam elements [2]. This approach has proven to be accurate but induces numerical stiff differential equations and a large number of degrees of freedom, which are an obvious disadvantage in terms of stability and computation time. This is particularly penalising in the early stages of the vehicle development, as a large amount of simulation runs are generally needed in order to optimise the suspension layout. To address this trade-off, this paper introduces an approach that models the deformation accurately, but neglecting mass and therefore the dynamics of the leaf spring itself
