Experimental and numerical analysis of flat cars connections between pivoting stanchions and main longitudinal beams
Апстракт
This paper presents experimental and numerical strength analysis of some existing
designs of connections between pivoting stanchions and main longitudinal beams of flat cars, pointing out the problem of possible appearance of high contact stresses at some contact surfaces, that might cause some local deformations within plasticity range. Criterion set in the applicable standard requires that two side stanchions fitted to the wagon and positioned opposite each other, shall be able to withstand, without residual deformation, a force of 35 kN acting at 500 mm from
the bearing centre of the stanchions in a horizontal direction towards the outside of the wagon. Meeting this criterion and staying inside the limited available space, leaves only minor changes of dimensions of moving parts in a contact as a possible solution of this problem.
