| Abstract: | Based on the results of field test of full-scale cars and reductive scale simulation test of simulated flow and of uniform flow in wind tunnel, this paper pinpoints the study of aerodynamic characteristics of two typical types of railroad cars-passenger car with curved roof and triangle-roofed box car . Also covered in the paper are some feasible methods for increasing aerodynamic lateral stability of railroad cars and ways of judging dynamic similarities of passenger car wind tunnel tests. |
