The rigid truck curve negotiation model calculates the lateral wheel-rail forces associated with the negotiation of a section of curved track by a rigid framed locomotive truck for a variety of normal operating conditions. The model itself is of a quasi-static nature modeling the truck in static equilibrium for each set of input data. Each truck of the locomotive is modeled individually and is assumed to have a conventional center bearing connection from the bolster to the locomotive, which does not impact any rotational stiffness. (This is a valid assumption under the static context of the model). The model simulates two, three and four axle trucks. The model will also compute the curving forces under various external conditions.
