In order to study the dynamic response characteristics of the pulse wind tunnel balance foundation under the action of pulse aerodynamic loads, a pulse wind tunnel was taken as an example, and a typical aerodynamic load action type was selected. As a result, a simplified calculation method for dynamic characteristics of the pulse wind tunnel balance foundation such as displacement of the vertical direction, displacement of the horizontal direction, and rotation angle was established, and its reliability was verified by numerical simulation. The results show that under the action of a typical aerodynamic load, the balance foundation has a maximum vertical vibration amplitude of 0.001 75 mm and a frequency of 7.94 Hz; a maximum horizontal vibration amplitude of 0.002 83 mm and a frequency of 7.94 Hz; a maximum amplitude of the rotation angle of 0.000 34° and a frequency of 7.94 Hz. The typical aerodynamic load has little effect on the vibration of the balance foundation, and no resonance phenomenon occurs. Meanwhile, the maximum amplitude of foundation vibration increases with the increase in aerodynamic load, and the frequency of foundation vibration increases with the increase in aerodynamic load frequency; under the condition of constant aerodynamic load, the maximum amplitude and frequency of foundation vibration gradually decrease with the increase in size; the maximum amplitude of the foundation vibration decreases with the increase in foundation soil properties, but the change of foundation soil properties has no effect on the foundation vibration frequency.
