The Changes of Shinkansen vehicles' nose shape
- 발행 : 2005.11.01
초록
This paper describes the changes of Shinkansen vehicles' nose shape by increasing train speed and according to the stream of time. As the speed increases, the length of the nose trends to lengthen longer. But the nose length does not increase as speed improves by optimized nose shape to reduce aerodynamic drag and micro-pressure wave in tunnels. Shinkansen vehicles nose shape can be classified into Advanced paraboloid type, Sharp-nosed type, Organic double-edged type and Flat-nosed type. In addition, it trends to be diversified and characterized more and more. In the near future, nose designs will be emphasized by the design concept including identity of each JR company based on optimized aerodynamic shape.
