Abstract: Disclosed is a hybrid shock absorption device that uses a magnetic effect, a spring effect, and a vibration prevention effect to have an increased shock absorption capacity and improved efficiency and performance while preventing vibration and thereby reducing shock absorption time, so as to be applicable to space probes and space structures. A damping effect is generated when a rod (40) pushes a moving magnet (50) into a copper pipe (30) due to an external shock to generate an eddy current effect from a relative movement between the copper and the magnet. Also, a buffer spring (100) is compressed to absorb the shock energy. At the same time, fixed magnets (500) are positioned at a lower end of the copper pipe (30) for the same poles to face each other so that the compression distance of the rod is limited. A ratchet (60) and a pole (80) are simultaneously operated to absorb the shock without any vibration and rebound caused by a restoring force of the buffer spring (100).
