Booster dynamic stiffness simulation component

The utility model provides a booster dynamic stiffness simulation component. The component comprises a dynamic stiffness simulation piece which can produce elastic deformation under the action of an external force and two connecting pieces. One end of one connecting piece and one end of the other connecting piece are respectively detachably connected with two stress ends of the dynamic stiffness simulation piece. The other end of one connecting piece and the other end of the other connecting piece are respectively rotationally connected with a bench support device and an aircraft wing face test piece rocker arm. According to the booster dynamic stiffness simulation component provided by the utility model, the dynamic stiffness simulation piece can accurately simulate the dynamic stiffness of a real airplane booster; a wing face test piece and the low order natural vibration mode of the support structure meet accuracy requirements; the dynamic stiffness simulation piece is detachably connected with the connecting pieces, the wing face position can be adjusted; compared with the existing technology, test equipment can be greatly reduced, and the test cost is greatly reduced; and the maintenance cost is low.
