Simulation design method for rolling hole patterns of steel rail

The invention discloses a simulation design method for rolling hole patterns of a steel rail, and belongs to the technical field of design and manufacturing of steel rail rolling equipment. The simulation design method for the rolling hole patterns of the steel rail, provided by the invention, is convenient to operate, high in automation degree and capable of improving the simulation analysis accuracy and avoiding errors. The method comprises the following steps: developing a set of simulation design software comprising a CAD (Computer Aided Design) hole pattern design module, a CAE (Computer Aided Education) hole pattern optimization module and a CAM (Computer Aided Manufacturing) hole pattern processing code generation module, and calling corresponding database information through the modules respectively; designing the rolling hole patterns of all rolling passes of the steel rail, dividing finite element grids for the rolling hole patterns with different specifications, establishing and correcting a related boundary condition model, and generating CAM codes of the rolling hole patterns of rollers corresponding to all the rolling passes. Due to the fact that the design and optimization of the rolling hole patterns of the steel rail and the generation of CAM processing codes are completed through the software respectively, the operation is simplified, the efficiency is improved, and the production cost is reduced.
