ANALYSIS OF WHEEL RAIL FORCE AND FLANGE FORCE DURING STEADY STATE CURVING OF RIGID TRUCKS
The wheel/rail forces and flange forces resulting from steady state curve negotiation are developed through analysis of a rigid two-axle truck. The analysis provides closed form relations for estimating wheel/rail forces, flange forces, truck angle of attack and sliding conditions for this type of truck as a function of curve radius. The wheel profiles are modeled by conical wheel treads with vertical wheel flanges and flange friction effects are included. The theory used includes both linear and nonlinear creep.
