摘要: Since no effective experimental approaches have been proposed to assess wheel and rail (W/R) contact performance till now, numerical computational analysis is known as an alternative approximately simulate the W/R interaction. In this paper, one procedure on basis of explicit finite element method analyse complex stress state contact. Moreover, a novel refining developed utilized discretise both solid model. This model considers realistic geometry bilinear kinematic hardening material. The effects points, friction force stiffness dynamic response wheel-rail interaction are investigated. Based these results, it can be noticed that not only provides much results but also flexible efficient enough for dealing with different operational parameters. Also, worth mentioning limited straight tracks, easily extended used curved tracks turnout well.
