• Abstract:
  This paper describes a planar or two-dimensional model to ; examine the gross motions of rail cars in a generalized train ; derailment. Three coupled, second-order differential equations ; are derived from Newton's Laws to calculate rigid-body car ; motions with time. Car motions are defined with respect to a ; right-handed and fixed (i.e., non-rotating) reference frame. The ; rail cars are translating and rotating but not deforming. ; Moreover, the differential equations are considered as stiff, ; requiring relatively small time steps in the numerical solution, ; which is carried out using a FORTRAN computer code.
