| Abstract: | The commonly used wheel and rail profiles data representations are studied,corresponding specifications are proposed.Then,rules of storing graphics data in the dxf file are analyzed,in order to achieve the mutual conversion between different formats of wheel and rail profiles data,which are expressed by analytical geometry or discrete points.Through MATLAB software programming,corresponding conversion software is developed,it can transform different undistorted data of wheel and rail profiles expressed by different representations. |
