摘要：
The vertical dynamic vehicle-track interaction in a railway crossing is simulated in the time domain based on a moving Green's function approach in combination with an implementation of Kalker's variational method to solve the non-Hertzian, and potentially multiple, wheel-rail contact. The method is demonstrated by calculating the wheel-rail impact load and the sleeper-ballast contact pressure for a hollow-worn wheel profile passing over a nominal crossing geometry.
