The invention discloses a double-force-source thrust vector testing and transferring calibration rack which is used for connecting a force generating device with a dynamometer. The double-force-source thrust vector testing and transferring calibration rack is applied in a thrust force testing system and particularly relates to a rocket thrust force testing system. The double-force-source thrust vector testing and transferring calibration rack is composed of the components of transferring ends, a loading flange, a calibrating flange, mounting bolts, etc. A parallel structure is adopted for the two transferring ends. The two transferring ends are connected with each other through an annular structure. The annular structure is welded with a connecting board through ribs. The two transferring ends are respectively provided with a hoisting hole for measuring two points on the two force sources which are separated from each other by a long distance. The double-force-source thrust vector testing and transferring calibration rack is advantageous in that an integral structure is adopted for the whole body of a transferring rack; relatively high rigidity and high inherent frequency are realized; a dynamic measurement precision is improved; furthermore a hollow front-projected spoke-shaped structure is adopted for the whole body, thereby reducing self weight, reserving a mounting and debugging space for a calibration device, and realizing simple structure, convenient mounting and convenient adjustment.
