Leyland experimental 2-axle vehicle (R1) calculation of vertical wheel/rail forces for a dipped joint comparing conventional and SAB resilient wheels (IM-DOS-087)

The theoretical investigation shows that SAB resilient wheels will reduce the vertical dynamic track forces, by up to 30 per cent compared with conventional wheels. This can only lead to reducing the rail bending moments, wheel/rail contact stresses and sleeper loads. Without recourse to track measurements being implemented this cannot...
