Increasing the number and diversity of rail focused courses is an important step in rebuilding America’s railway education infrastructure. Currently, most college level rail courses are on railway civil engineering topics. A new course jointly developed by the Universities of Tennessee and South Carolina addresses railway operations. Providing engineering students with a better understanding of operations can improve infrastructure design and maintenance practices. Click here to read the detailed brief.
This investigation describes a new nonlinear formulation based on the absolute nodal coordinate formulation (ANCF) for modeling the dynamic interaction between rigid wheels and flexible rails. The generalized forces and spin moments at the contact points are formulated in terms of the absolute coordinates and gradients of ANCF finite elements used to model the rail. To this end, a new procedure for formulating the generalized ANCF applied moment based on a continuum mechanics approach is introduced. Click here to read the detailed brief.
