FREIGHT CAR DYNAMICS

摘要: The objective of this research project was to develop techniques analyze the lateral dynamic behavior railroad freight cars. effort included development and correlation theoretical for predicting car behavior, use investigate present proposed designs. sponsored by FRA with support cooperation from Association American Railroads Union Pacific Railroad. A number models analysis approaches were developed on tangent track. These differ widely in complexity. An output is understanding appropriate each model technique. Extensive field tests planned carried out (AAR), Railroad (UP), Martin Denver Division. conducted AAR UP. Eight different vehicle configurations tested, at several speeds both curved Data obtained these used comparisons predictions response.
