Mechanics-action analysis and research about wheelset dismantler in pressed conditions

Process flow of wheelset dismantler and the necessity of mechanics analysis about it are described in this paper. The mechanics-action of wheelset dismantler´s connected beam in press-fit condition is analysed using universal finite element software ANSYS, connected beaam stresses and deformations are calculated and compared each other. The results indicate that the maximum stress of connected beam in the press-fit condition is all less than the yield stress, and it also proves that strength and stiffness of connected meet the strength and precision of wheelset press-fit.
