The invention relates to the field of aerospace propulsion systems, in particular to high and low temperature alternating test equipment and method for simulating the ignition working condition of an aerospace propulsion system. The heating end of the heating device and the refrigerating end of the cooling device are arranged on the inner surface of the vacuum chamber and are arranged in parallel, a movable heat insulation mechanism is arranged on the outer side of the heating end of the heating device and the outer side of the refrigerating end of the cooling device in the vacuum chamber, and the heat insulation mechanism reciprocates between the heating device and the cooling device. The sample rack is positioned in the vacuum chamber and fixed on the movement mechanism in the center of the vacuum chamber, the movement mechanism is connected with the driving device, and the driving device drives the movement mechanism to move so as to control the sample rack to move back and forth between the heating device
