The invention provides a bi-shaft continuous rotation test stand and belongs to the field of a flight simulation device. The bi-shaft continuous rotation test stand comprises a rotating table, a sample box, a rotation frame, a rotation transverse shaft, a rotation longitudinal shaft and a hollow rotation shaft, and is used for communicated with a refrigeration pipe of a refrigerating system and a plurality of bearings; the hollow rotation shaft is arranged coaxially with the rotation transverse shaft; meanwhile, the refrigeration pipe is arranged in the hollow rotation shaft; and during the rotation test, the rotation transverse shaft rotates and the hollow rotation shaft does not rotate, thereby ensuring the refrigeration pipe does not have the problem of cold air choke due to rotation, improving refrigeration effect and prolonging the service life of the refrigeration pipe.
