Railcar kinetic collision energy converter involves modules joined to car structure stiffly but otherwise drilled out to form deformable crush sectors to absorb kinetic energy of collision etc.

摘要

Modules (1-4) joined to the car structures in line of travel are stiff at the joins but otherwise drilled (6) or recessed to provide deformable sectors. The modules are heat-treated in their deformable or crush sectors and in any case are prefabricated and held in a frame (5) and so integrated into the railcar bodies.
