Research and Application on the Visualization Algorithm of Wheel-Rail Contact

Abstract:

A visualization algorithm was presented for the optimization of geometrical shape matching in the wheel-rail contact system. The algorithm of the subsection cubic spline interpolation was adopted to fit the wheel-rail profiles curves, and curve boundary was got by the finite difference method; furthermore, the wheel-rail contact positions were figured out by computing the roll angles of wheelset iteratively with the dichotomy. Based on MATLAB and Visual C++, the wheel-rail contact geometrical parameters were calculated and visualized, the simulation results show the algorithm has the strong robustness.
