Dgm friction
WebOne of the major challenges for the simulation of the longitudinal dynamics of heavy-haul trains is modeling the in-train forces. The freight cars draft gear mechanisms (DGM) are known for its highly non-linear behavior, with fast force transitions between the loaded and unloaded operational stages. Accurate models that represent the constructive … WebFriction Model. In friction models with such properties, when the surfaces in contact are incommensurate, or when the ratio of periodicity along sliding surfaces is an irrational …
