Abstract:Research purposes: This paper studies the stress and deformation of the welded turnout group of passenger dedicated line with the Rail—Fastener—Sleeper—Bed finite element model and offers the calculating method for the temperature force and displacement of welded turnout group with a non—linear finite element program for the purpose of providing the references to the design,construction and maintenance of the welded turnout group of passenger dedicated line.
Research conclusions: The experimental study results show that the glass foam revetment is better than the sward revetment in insulated during the experimental period, which can reduce the seasonable thaw
