The lateral aerodynamic performance of high-speed train is studied by computational fluid dynamic technology according to a number of geometric parameters. First, three train models with different length of train nose are taken into consideration while keeping the nose shape the same. The results show longer and tapering nose shape can improve the lateral aerodynamic forces effectively. Second, after comparison between train models with different bottom design, it is found that the train with round underbelly shape has less lateral aerodynamic forces. Finally, aerodynamic characteristics are compared between train models with and without flush covers. The results show the larger lateral loads are manifested when the skirt plates are removed.
