摘　　要：本文依据全尺寸车辆现场实测和均匀流、模拟流风洞缩尺模拟实验结果,重点研究了弧形顶面客车和三角形顶面棚车两种代表性铁路车辆的气动横向稳定性等气动特性,并且提出了提高铁路车辆气动横向稳定性的可行途径。本文还讨论了判断客车风洞实验动力相似的特征等。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.
