The invention discloses a simulation test system of an aircraft, which relates to the field of aircrafts and comprises a test box body, a horizontal mounting seat, a vertical mounting seat, an excitation transducer, a concentrated force simulation unit, a horizontal centering unit, a vertical centering unit, a temperature and humidity simulation unit, an acquisition module and a comprehensive control unit. The test piece is installed on the excitation transducer, and the excitation transducer provides high-frequency load excitation in the horizontal direction or the vertical direction for the test piece. The concentrated force simulation unit provides concentrated force static loads in the horizontal and vertical directions for the test piece; the horizontal centering unit and the vertical centering unit are respectively used for counteracting concentrated force acting on the excitation transducer in the horizontal direction and the vertical direction, so that the vibration output end of the excitation transducer, the horizontal mounting seat and the vertical mounting seat are always in working neutral positions, and normal excitation can be realized; the temperature and humidity simulation unit provides a temperature and humidity environment for the test piece; the comprehensive control unit carries out coordinated control on the units, and vibration-concentrated force-temperature compound control is achieved.
