WebbTwo rolling contact theories are used in this study. They are the linear theory of rolling contact and the simplified theory of rolling contact [6]. The linear theory concerns cases where wheel creepage is small, such that the entire contact area is assumed to be in adhesion. That is, no slip occurs throughout the contact patch.
