| Abstract:Taking the axle box sealing window frame of a railway freight car as the research object, as to the problem that the cracks often occur at the fillet area with flanging during the stamping production, the initial analysis is performed on the basis of manual book, the unfolding is numerically simulated by finite element analysis method, and a reasonable expansion shape and a rational stamping process scheme are obtained. |
