A steering pad on a train is meant to reduce the force on the wheel while moving along a curve in the rail. A new steering pad was desired with properties tuned for a new suspension system design. An anisotropic, compliant pad was designed for a specific stiffness anisotropy, 20:1. Finite element analysis was performed on various models as a guide to designing a pin with the desired stiffness ratio. A design was chosen for a prototype made of thermoset polyurethane, a similar material to that currently used. Experiments were performed on the prototype pad model to determine vertical and lateral pin stiffness under different loading conditions.
