Traction calculation for rail transport in force in the train ( including locomotive traction , resistance train , the train braking force ) under the action of orbiting scientific computing and related issues . It mechanics as the basis for scientific experiments and advanced manipulation of empirical , analytical train operation in a variety of phenomena and principles , and for solving the design of rail transport operators and some of the key technical issues and technical and economic issues . Part of the train traction current calculation software in the train model train on a single particle model , with some automatic calculation function , but due to a single particle model , resulting in low accuracy , not better meet customer needs. Another part of the train traction calculation software in multi- particle model trains calculation model accuracy are met, but in the calculation process, the need for frequent manual intervention locomotive operation to complete, requires a lot of manpower and time. Therefore, the development of a high accuracy , with automatic calculation function traction calculation software, can greatly reduce the labor intensity of traction calculation work , improve labor efficiency , greatly enhancing the use of technology level of traction calculation for the relevant departments to provide good computing tool , with a very broad application prospects and a good practical significance. In this paper, the system point of view , will train traction calculation as a multi- problem solving methodology . The traction calculation software requirements analysis , based on the detailed design of software functionality , the software is divided into three modules : data management, computing and software interface traction . Traction article introduces computational theory , using an improved single- particle model trains , according to train stress analysis , the train and the various constraints of the equations of motion design Traction automatic calculation algorithm ; then introduced the theory of relational database design and build a system database ; and in accordance with the system interface design principles , design -friendly interactive interface . Finally Applications VC 6.0 encoded and passed the test, get a high accuracy automatic calculation function, database management, friendly interface train traction calculation software .
