The invention relates to the technical field of aircraft tests, and discloses an aircraft conical cabin joint thermal intensity assessment test device which comprises a test piece fixing tool. The pneumatic thermal simulation device is arranged at the front end of the test piece fixing tool along the central axis of the test piece fixing tool; the pneumatic pressure simulation device is arranged at the front end of the pneumatic thermal simulation device; the pneumatic thermal simulation device is installed on a position adjusting mechanism which can linearly move to adjust the front-back position of the pneumatic thermal simulation device, and the pneumatic thermal simulation device is used for providing thermal loads for the connection position of the front section and the rear section of a test piece restrained by the restraining mechanism at the rear end and the front-back area of the test piece. And the pneumatic pressure simulation device is arranged below the conical front section of the test piece and applies an upward force load to the lower part of the front section of the test piece. According to the invention, the flight environment of the aircraft during flight can be reproduced more truly, and the reproduction of aerodynamic heat and aerodynamic pressure during high-speed flight of the aircraft in a high-altitude environment is met.
