The Nadal criterion study of a passenger car with independently rotating wheels

Abstract

Authors of an article compare the dynamic characteristics of cars with integral wheel sets and wheel sets with independently rotating wheels by comparing Nadal criterion values and their laws of change when the car runs on various curves and straight sections of the railway. The studies show that in curves of low radius, laws of change of Nadal criterion values are fundamentally different than in straight railway sections; it has a significant impact on the comparison of dynamic properties of passenger cars with integral wheel sets and wheel sets with independently rotating wheels.
