Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 As shown, a dual-degree-of-freedom vibration active control platform with controllable damping stiffness of the present invention includes a cross beam skeleton 2 and a square base 11 connected by a flexible hinge 10, and the cross beams of the cross beam skeleton 2 are distributed on the square base 11 In the diagonal direction, a structural column 1 is installed at the center of the cross beam skeleton 2, and a sensor 3 and an actuator 5 are respectively connected between the lower part of the diagonal top of the cross beam skeleton 2 and the square base 11, and four limit columns 6 They are respectively placed between the cross beams of the cross beam skeleton 2 and the square base 11 and are close to the symmetrical positions of the sensor 3 or the actuator 5. There is a preset gap between the limit column ...
