Simplified equations of motion for an idealized representation of the sliding sill cushion unit are developed using experimental data from the literature. These equations are then coupled with the fundamental mass, stiffness, and damping characteristics of conventional and sliding sill rail cars to provide an analytical model of the action of sliding sills in impact situations. The equations are solved in closed form for simple impacts and are solved numerically for more complicated impacts. The numerical results are compared with experimental data from an actual switchyard impact.
