Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 As shown, the present invention is a dual-axis decoupling acceleration dynamic calibration platform controlled by sinusoidal displacement, including a calibration platform 9 on which an accelerometer is placed, and a first actuator connected to the calibration platform 9 to realize its sinusoidal displacement movement along the y direction 6. A first flexible hinge 7 and a second flexible hinge 8 are connected on both sides of the calibration platform 9 perpendicular to the actuating surface, that is, in the y direction. The thickness of the first flexible hinge 7 and the second flexible hinge 8 is thin at the hinge, The calibration platform 9 is kept moving along the y direction with sinusoidal displacement through deformation, and after the thickness in the x direction perpendicular to the y direction, the mo...
