The invention relates to a high-speed impact simulation test device for a spacecraft landing test, and belongs to the technical field of extraterrestrial celestial body landing and takeoff tests. The rotary speed increasing mechanism is axially and horizontally placed at the top of the supporting frame; the lifting motor is in coaxial butt joint with the rotary speed increasing mechanism through the clutch; the counter weight is placed on a top platform of the supporting frame; one end of the first rope is connected with the counterweight, and the other end is wound at the small-diameter end of the rotary speed-up mechanism; one end of the second rope is wound at the large-diameter end of the rotary acceleration mechanism, and the other end of the second rope naturally hangs down; the detacher is mounted on the second rope; the bottom end of the detacher hooks the top end of the third rope; the third rope is connected with the parachute system; the parachute system and the buffer cushion are placed on the bottom face of the supporting frame, and the buffer cushion is located under the balance weight. The parachute pack can be pulled out at the highest speed of 40m/s, and parachute pulling performance tests of parachute systems of different specifications can be realized; and meanwhile, other high-speed impact test requirements can be met.
