SHOCK DAMPING DEVICE ESPECIALLY FOR CONTROL RODS IN NUCLEAR REACTORS
A shock damping device designed to absorb kinetic energy in order to bring a falling body to rest, consists of a tubular piece having a fairly uniform cross section. This tubular piece is provided along a part of its length only, with preformed depressions, so that a large enough axial compressive force acting on the piece, causes a deformation thereof; the piece offers a fairly constant resistance to deformation. During the compression induced by the deceleration forces, triangular or polygonal folds are produced at the places where the depressions are situated. The said piece is deformed beforehand by being submitted to an axial compression, so that at least one fold is formed. Suitably, the wall thickness of the tubular piece may increase progressively along its length and the ends of the piece may be reinforced to resist deformation. (NPO)
