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.
