摘要：

A case study involving the development of a customized wheel profile is discussed. The process of designing a new standard interchange profile for North American railroads is described. Alternative profiles were derived through two techniques: an average worn wheel profile and profiles based on expansions of rail shapes. Both these methods provide good base designs for candidate profiles. However, the initial wheel shapes produced were modified to suit the specific concerns of the task involved. This was done through careful computer analysis of the dynamic and contact stress characteristics of each wheel.
