    Abstract:

    To improve grinding quality and enhance vehicle dynamic performance, this paper presents an inverse design method for determination of rail grinding profiles. This method aims at optimizing rolling radii difference after grinding. It uses designed wheel-rail contact distribution as boundary conditions. With the designed rolling radii difference and contact distribution, a numerical algorithm is deduced to find the grinding profiles. Computer simulation results prove the validity of the proposed algorithm. This method not only can solve both sides design problem, but also can solve single side design problem. By designing different rolling radii difference and contact distribution, it could satisfy different grinding requirements.
