Study Friction between Wheel and Rail by Using Molecular Dynamics Method
Aiming at researching friction process on the influence of train rolling contact properties between the wheel and rail,using the basic principle of Molecular Dynamics Simulation and Embedded Atomic Method theory,study the areas of adhesion within the contact patch area will gradually increase along with the occurrence of the friction process,research the increase process about the areas of adhesion within the contact patch area by means of Molecular Dynamics simulation model and simulation algorithm.For the study of friction on the surface about changes and micro-dynamic behavior,understanding the influence of the friction process on the train rolling contact characteristics,provides a numerical simulation based on microscopic approaches and methods.The results show that the method is easy to achieve a large time scale,a large number of atoms of the dynamic simulation.
