Analysis of Steady State Curving Performance of the Rail Vehicle with Three Bogies (2nd Report, Effects of Each Parameter on Lateral Force)

摘要

This paper deals with analytical results of steady state curving performance of a railway vehicle with three bogies like a driving car. First, the effects of uncertainty of input data such as the friction factors between rail and wheel, the friction moment M acting on truck and body, on the lateral force is discussed. Next the effect of the spring stiffness on the lateral force and flange force is discussed. As a result, it is clarified that 10 deviation from standard values of all uncertainty factors gives about 10 error to the analytical results and one or two order change of the spring stiffness is necessary in order to change the lateral force.
