The invention discloses a test device for simulating cold launching takeoff of an extraterrestrial celestial body in a low-gravity environment. The test device comprises a supporting frame, a movable sliding table system, an active rope system, an ejection device and a spacecraft simulation part. The invention also discloses a test method which comprises the following steps: the motor rope combination in the vertical direction performs gravity unloading on the spacecraft simulation part, and controls the attitude of the spacecraft simulation part; when the spacecraft simulation part rises to the highest point, the position and the posture of the spacecraft simulation part are locked; the motor ropes in the horizontal direction and the vertical direction are combined to simulate thrust in the horizontal direction and thrust in the vertical direction generated when the spacecraft engine is ignited; and after the ignition duration requirement is met, the motor rope combination in the inclined direction applies braking pulling force to the spacecraft simulation part, so that the spacecraft simulation part decelerates and stops moving. According to the invention, the test verification of the ejection and ignition process of the cold launch takeoff and rising on the ground can be realized, and the stress condition and the movement condition can be effectively simulated.
