Six-degree-of-freedom heavy-load low-frequency excitation platform based on air springs

The invention belongs to the related technical field of mechanical dynamics, and discloses a six-degree-of-freedom large-load low-frequency excitation platform based on an air spring, the excitation platform comprises a vibration exciter, the vibration exciter comprises an upper end plate, a base and a horizontal swing mechanism, the horizontal swing mechanism is partially arranged in the base, and the upper end plate is arranged on the base. The upper end plate is connected to the base; the base and the horizontal swing mechanism jointly form an air spring, and the air spring and the upper end plate are oppositely arranged. The upper end plate is used for connecting a load; the shock excitation platform enables the air springs to deform by introducing air into the air springs so as to float the upper end plate, and then the load is floated. The influence of the target load gravity on excitation is overcome through the air spring, the rigidity in the vertical direction is reduced, the motor provides full-band
