Title   Contact stress and deformation between domestic   overloaded  QU120 rail and wheel
Abstract
domestic QU120 overload rail are used to transport ladle for steelworks,which wheel pressure is 71.5 tons.In use, there will be plastic and longitudinal cracking pressure exhibition.The cause of it has yet not to be analyzed,which Seriously affected the normal steel production.Study of this subject, adopting three-dimensional contact finite element method,structuring model and discreting grid through ProE and HyperMesh,using three-dimensional contact element and mechanical mode to analysis the overloaded rail contact stress on QU120 and contact deformation.In order to identify the causes of QU120 overloaded rail exhibition and cracking plastic pressure. 源`自<六:维;论-文>网/www.lwfree.cn
