Embodiment Construction
[0112] The technical solution of the present invention is described in detail in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following implementation situations.
[0113] The active vibration control method of wrinkled film based on in-plane regulation of the present invention can add two groups of voice coil motor drive modules on the basis of the static experimental device, which are used to adjust the displacement in the X direction and the Y direction respectively, through the voice coil motor The slider is stretched to adjust the displacement of the cable, and the tension on the cable is changed. The tension sensor fixed on the slider of the voice coil motor is used to monitor the tension in real time, and the grating ruler outputs and feeds back the displacement in real time. A knocking device is installed on the back of the film, and the out-of-plane disturbance is simulated by the impact method, and the out...
