Experiment research on friction coefficient between a steel plate and rail in transient sliding thermal contact through a pendulum

The main goal of this article is to study the friction coefficient of wheel/rail transient sliding thermal contact through a pendulum. A new method is firstly established to analyze the friction coefficient. The formula for calculating the friction coefficient is not dependent on material and therma...
