MECHANICAL DEVICE UNDERSTANDING AN EXTENDED STRUCTURE ELEMENT FOR SHORTING AT LEAST PARTIALLY SOME DEFORMATION SHOCKS

摘要

"mechanical device comprising an elongate frame member intended to at least partially dampen some shocks by deformation". The invention relates to a mechanical device comprising an elongate frame member for at least partially cushioning some shocks by deformation. this frame element or part comprises a chosen straight section profile, this profile being provided with localized changes (244 2, 244 3, 244 4) of respective shapes and positions, chosen to substantially satisfy a given law of strain under stress, compression set on the workpiece axis, and shaft torque perpendicular to a plane passing through this axis. This law involves a phase of energy absorption, followed by a disappearance of the piece.
