Problems solved by technology

[0002] The flexible plate structure has the advantages of light weight, low energy consumption, and flexible operation, and is widely used in aerospace and industrial production fields. The solar wing used on space stations and spacecraft is a large flexible plate structure, but due to the low rigidity of the flexible plate , flexible characteristics, the low-frequency vibration generated after being disturbed will last for a long time, if it is not controlled, it will affect the stability of the system, and the consequences will be disastrous

Embodiment

[0042] Figure 1-Figure 6 As shown, a multi-flexible board vibration detection and control device with a base swing, including a multi-flexible board body part, a directional pointing drive part, a swing base part and a control part;

[0043] The multi-flexible plate body part includes four hinged leaf structures 5 and a central body 1, the four hinged leaf structures are installed in a 90° circle with respect to the center axis of the central body, and each hinged leaf structure includes two Flexible board, the size and material of the two flexible boards are exactly the same, and the two flexible boards are connected by upper and lower hinges. There are eight flexible boards in this structure. One end of each hinged leaf structure is free, and the other end is mechanically clamped The device 8 is fixed, that is, one end of a flexible board is fixed with the mechanical clamping device, the other end is connected with another flexible board, and one end of the other flexible b...

Abstract

The invention discloses a multi-flexible plate vibration detection and control device and method for base swing, including a multi-flexible plate body part, a directional pointing drive part, a swing base part and a control part; the multi-flexible plate body part is composed of four hinged plates Each hinged plate leaf structure is composed of two flexible plates connected by hinges, one of which is connected to the central body through a mechanical clamping device; the gyroscope sensor obtains attitude information, and is driven by an electric cylinder combined with a single-axis turntable Orientation is achieved by means of a servo motor; the swing part of the base meshes with the arc-shaped rack through the servo motor drive gear, and the guide is realized through the guide rail on the base; the visual measurement unit is installed on the frame-shaped bracket, and the piezoelectric ceramic sensor distributed on the flexible board is used It is used for vibration detection; the piezoelectric driver is used as an actuator to suppress vibration; the device can be used to study the orientation, vibration detection and vibration control of multi-flexible boards under the condition of base swing.

Description

technical field [0001] The invention relates to the field of flexible structures, in particular to a multi-flexible plate vibration detection and control device and method for a base swing. Background technique [0002] The flexible plate structure has the advantages of light weight, low energy consumption, and flexible operation, and is widely used in aerospace and industrial production fields. The solar wing used on space stations and spacecraft is a large flexible plate structure, but due to the low rigidity of the flexible plate , Flexible characteristics, the low-frequency vibration generated after being disturbed will last for a long time, if it is not controlled, it will affect the stability of the system, and the consequences will be disastrous. [0003] The solar panels on the spacecraft are usually distributed in different orientations, and during the attitude adjustment process, the vibrations caused by the interference of the solar panels in different orientation...
