THE FRICTION DAMPER

Constant-force dampers are attractive for rolling stock with small differences between loaded and empty conditions such as passenger coaches but are not for freight wagons where the tare/loaded weight ratio is high which calls for displacement-responsive damping. Friction damping and viscous-damping are mathematically compared and assessed. The author warns of pitfalls when 'scaling down'.
