ESTABLISHMENT OF DAMPENING REQUIRED FOR CONTROL OF RAILROAD TRUCK HUNTING
All present analyses into "the hunting phenomenon" are based on evaluation of the effective conicity of the wheel tread and the resulting creep and friction forces, and their interaction with the various degrees of freedom of the dynamic system of freight car and it's suspension. This paper offers a means to calculate the critical dampening that can control hunting, disregarding the geometry of wheel tread profiles which tends to change with wear. The equations for frequency and dampening required for control of the motion are based on the elasticity of the system at the area of contact between wheel and rail, and the castering characteristics of the railroad vehicle truck.
