Rail wear and remaining life prediction using meta-models
2.1. Rail wear calculation. Figure 1 schematically shows the process of rail wear calculation, where different combinations of input parameters are fed into a multi-body dynamics simulation. The resulting wheel-rail contact parameters of these simulations serve as input for the physical models implemented in Matlab that yield the amount of wear …
