The invention relates to a skid undercarriage drop test device and a gravity center verification method. The skid undercarriage comprises cross beams arranged front and back, mounting connectors of the front cross beam and the rear cross beam and skid pipes on the two sides. The test device comprises a simulation fuselage frame, a transverse triangular beam, a mass block, an adjusting connecting screw rod, a transverse triangular beam connecting piece, an undercarriage rear cross beam mounting seat, an undercarriage front cross beam mounting seat and a damper mounting seat. The simulation fuselage frame is fixed above a cross beam of the skid type undercarriage through an undercarriage rear cross beam mounting seat and an undercarriage front cross beam mounting seat; the damper mounting seat is fixed on the simulation fuselage frame; the transverse triangular beam is arranged above the simulation machine body frame and connected with the simulation machine body frame through a transverse triangular beam connecting piece, a plurality of preset adjusting hole positions are formed in the transverse triangular beam and the simulation machine body frame, and the mass block is fixed through an adjusting connecting screw penetrating through the adjusting hole positions. And the ski undercarriage drop test under the conditions of different center-of-gravity positions and effective mass sizes can be met.
