TWIN WIRE BENDING KINETIC ENERGY ATTENUATION SYSTEM

摘要

A mechanism for decreasing kinetic energy includes a carriage (18) to connect to an object, a first wire (14) passing through a top portion of the carriage, a second wire (16) cotenninous with the first wire at a top end and a bottom end, a spreading wheel (20) axially fixed in a center position of the carriage between the first and second wires to plastically deform the first and second wires from a substantially parallel configuration to conform to a circumferential surface on two opposing sides of the spreading wheel as the carriage moves from the top to the bottom end, and a pair of despreading wheels (22, 24) axially parallel to and oriented proximal to the spreading wheel such that the first and second wires are deformed by a circumferential surface of each of the despreading wheels such that they are deformed again as the carriage moves from the top to the bottom end.
