Accurate numerical modeling of railroad vehicle systems is vital to increasing railroad safety and efficiency. The formulations of both flexible and rigid multibody dynamics are particularly well-suited to the studying of railroad vehicle dynamics. In this thesis, three topics in the modeling of computational multibody railroad system dynamics are presented.Dynamic brake curves for an EMD SD-40 locomotive 92 43. Diagram of a typical draft gear assembly 95 44. Force response curve of a Mark 50 draft gear under a dynamic load 96 45. Force-displacement curves used to simulate the behavioranbsp;...
