Aerodynamic Shape Design of the Bow Network Monitoring Equipment of High-speed Train
Abstract
In this paper, three different aerodynamic shape design of the high speed train bow network monitoring equipment were presented: The overall length, width and height size of the three designs are the same and design 1 was the original design; the edge of the windward face of design 2 was rounded compared with design 1; the angle between windward face and side face of design 3 became larger than that of design 1, and the width of the turning face was larger at the same time. By numerical computing: The aerodynamic performance of the equipment has nothing to do with the running speed of the train; Compared with design 1, the aerodynamic drag of design 2 is reduced by 2.3%, and the aerodynamic drag of design3 is increased by 1.4%. In design 2, the curve is more mellow, and the surface transition is more relaxed, so the aerodynamic drag is also the minimum.
