| Abstract | If traditional design method were adopted to design the head structure of high-speed train, lots of time would be taken and a large amount of workload be done and machining precision not be assured. After analyzing the characters of the design and the manufacturing of the head structure of highspeed train, the bend sheet-beam design software of the streamlined head structure of high-speed train was developed on the ARX of AutoCAD software and the Open I-deas of Ideas software flat roof, which is mainly based on the intersection theory between two Non Uniform Rational BSpline surfaces and 3-dimensional geometric modeling technique of solid. Grid structure made up of the bend sheetbeam ensures that the head structure design is carried through by the way of the loading structure tied in with the streamline shape, that the twisted beam is avoided to build, and the structure is provided with well technological characters of manufacture and assembly at the same time. Because the main edge of the bend sheet-beam is free-form curve, it can not been processed using NC machining tool directly. For every NC machining tool has its respectively character and its machining program is different from each other, according to the line approximation form of Non Uniform Rational B-Spline and the technique preferences of the NC machining tool, the numerical control machining software of the bend sheet-beam of the high-speed train head was presented based on the ARX of AutoCAD software flat roof. The machining problem of the bend sheet-beam is settled down. At present the both software are used to design the streamlined head structure of highspeed train in our country. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
