Figure 2 illustrates a primitive suspension model assembled from two multi-body leaf springs. A translational joint is used to handle the distance variations in length between the mounting positions against the leaf springs. A spring is applied to the translational joint to control the lateral motion of the axle. The simulation time increases significantly with a stiffer translational spring. A more realistic model can be assembled by adding revolute joint for the lateral and roll motion as well, but the simulation time for just one planar leaf spring is already long.
