Abstract
This chapter introduces the basic theories of rolling friction first, and then presents some of its applications, such as the high-speed train and the lunar vehicle. Friction coefficient is the commonest parameter to describe a friction resistance. For rolling friction, the following two kinds of friction coefficient are usually used to describe a rolling friction: dimensional rolling friction coefficient; and rolling resistance coefficient. The chapter presents the adhesion of rolling friction, the effect of adhesion on the speed of a train and the method of improving the adhesion of wheel/rail. Study on the mechanics of a wheel that rolls through the un-built lunar surface is very important. One of the basic purposes of studying the interaction between the wheel and the ground is to provide a reliable method to predict the traction force and the driving force for different kinds of walking device.
