Study on Impacting Characteristics of a Metro Vehicle

Abstract:

Article Preview

In order to analyze impacting characteristics of a metro vehicle, the impacting governing Eq. is established, in which, nonlinear stiffness and damping of a buffer, friction force between rail and wheel of the vehicles is considered. In terms of testing results, nonlinear stiffness and damping of the buffers is simulated. By numerical simulation, it is found that when moving trainset impacts standing trainset, because the impacting force, stroke of buffers located in impacting interface is the maximum, the capacity of the buffers must be large enough to avoid rigid impact; when trainset with different number vehicles impacts each other, the maximum impacting force is not only different from each other, but the stroke and energy dissipation of the buffers is also different; the capacity of buffers far from impacting interface may be small.
