PCT No. PCT/NL95/00029 Sec. 371 Date Sep. 19, 1996 Sec. 102(e) Date Sep. 19, 1996 PCT Filed Jan. 20, 1995 PCT Pub. No. WO95/20112 PCT Pub. Date Jul. 27, 1995A retardation system for adjustably reducing the speed of an object moving relative to the retardation system. The retardation system comprises a retardation mechanism to which is transferred the kinetic energy of the object when the speed of the object is being reduced by the retardation mechanism, and a computing device for computing the kinetic energy to be transferred to the retardation mechanism in the form of retardation forces, calculated over time, of the object during its retardation process. According to the invention, the retardation mechanism comprises a frame with a retaining device for removably and slidably receiving in the retaining device one of the ends of at least one force-absorbing element, the plane of this element extending at an angle relative to the axis of the frame, and the at least one force-absorbing element being slidable by its other free end in the plane of the element relative to the axis of the frame, in such a manner that the object, of which the relative direction of motion is generally aligned with the axis of the frame, while passing the at least one force-absorbing element, is in a predetermined effective contact with the other free end of this force-absorbing element, the amount of the contact between the object and the force-absorbing element being a measure for the magnitude of the kinetic energy to be transferred to the at least one force-absorbing element. |
