摘要: This paper present a solution to mitigate the growth of rail corrugation associated with resonance modes wheel set, using passive dynamic vibration absorber (DVA). To investigate relevance such on corrugation, complete multi-body model vehicle-track system has been first developed, including discreetly supported track as well finite element representation sets. Eciency is discussed in terms energy loss contact patch. Broad outlines for design DVA be mounted set are also given. Finally, simple experiment shows how damp two shaft single DVA, encouraging us think that it can case set.
