Embodiment

[0028] Such as Figure 1-Figure 2 As shown, a vibration detection device with a flexible structure connected by a cable includes a flexible structure part, a detection part and a vibration excitation part.

[0029] The flexible structure part includes a flexible structure, a flexible fixing frame, a rigid board and a flexible cable. The flexible structure is composed of rigid boards 9 connected in N rows and M columns. N and M are integers. This embodiment consists of three rows and eight columns. Twenty-four rigid plates of the same size are connected and fixed by flexible lanyards 10 and flexible fixtures 8. The specific method is that each rigid plate has two flexible lanyards on each side of the upper, lower, left, and right sides, and the two flexible lanyards are located at each On the left and right quarters of a side. Adjacent rigid boards are connected by flexible cables, and the flexible fixing frame is fixed to adjacent rigid boards by flexible cables. The distanc...

Abstract

The invention discloses a vibration detecting device and method for a towing cable connecting flexible structure. The vibration detecting device comprises a flexible structure portion, a detecting portion and a vibration excitation portion, the flexible structure portion comprises a flexible structure, a flexible fixing frame, rigid plates and a flexible towing cable, N-row and M-column rigid plates are connected to form the flexible structure, the detecting portion comprises a guide rail, a high-speed camera, a cloud deck and a slider, and the vibration excitation portion comprises a computer, a power amplifier, a signal generator and a vibration exciter. According to the vibration detecting device, a detecting body can be measured in a non-contacting manner, additive effects cannot be provided for a system, robustness of the system is high, and more accurate vibration information of a towing cable connecting flexible mechanism is acquired.

Description

technical field [0001] The invention relates to the field of vibration measurement of flexible structures, in particular to a vibration detection device and method for connecting flexible structures with drag cables. Background technique [0002] The solar battery wing is a power generation device composed of solar battery slices combined in series and parallel and its supporting structure. It is connected to the cabin structure of the space station, and is folded and fixed on the side wall of the cabin structure during launch. The program unlocks, releases, deploys and tracks the sun as instructed. According to the development and application of solar cell wings of foreign space stations, a complete space station solar cell wing usually needs to include several parts such as solar cell array mechanism structure, solar cells and circuits, and solar cell wing extension mechanism. [0003] Non-contact measurement has many advantages over traditional sensor contact measurement...
