Solid rocket engine dynamic centrifugal overload ignition testing device and method

The invention provides a solid rocket engine dynamic centrifugal overload ignition testing device and method. The device comprises a centrifugal machine transmission system, a centrifugal machine rotating arm system, a balance weight cabin, an instrument cabin and a rotating cabin. The rotating cabin is arranged in a hollow structure at the outer end of a rotating arm. The side face of the rotating cabin is connected with the rotating arm through a rotating shaft. The rotating cabin is further hinged to the rotating arm through a screw type adjusting device. The length of the screw type adjusting device is adjusted so that the rotating cabin can be driven to rotate around the rotating shaft connected with the rotating arm. A solid rocket engine is installed in the rotating cabin through aspoke type fastening device. The spoke type fastening device comprises a conical cylinder, and the conical cylinder is formed by combining two semi-arc seats with the axial taper through a connectingbolt. A radial expansion-p
