Problems solved by technology

[0002]With the rapid development of today's aerospace industry, human beings are increasingly demanding the efficiency of space exploration. The food supply of the space station staff has a huge impact. After the space shuttle arrives near the target space station, it is very difficult to dock the space shuttle and the space station due to factors in the space environment. Difficult, and may even lead to serious delays in material delivery

Abstract

The invention discloses a flexible arm spatial vibration characteristic analysis device and method based on multiple cameras. The device comprises a support system part formed by a two-degree-of-freedom large arm movement device part driven by a double-servo motor, an experiment pedestal and a slider tripod platform and a multi-camera space measurement and analysis system part formed by three cameras. The two-degree-of-freedom large arm movement device part is fixedly installed on the experiment pedestal, and the multi-camera space measurement and analysis system part is installed on the slider tripod platform. The multi-camera space measurement and analysis system is applied to measure the space position of a mark point on a two-degree-of-freedom large arm under a movement condition, the space position information of the obtained mark point is analyzed, the information of bending vibration and torsional vibration of the two-degree-of-freedom large arm in a three-dimensional space is obtained, thus the active control of the vibration of the two-degree-of-freedom large arm can be realized, and a simulation experiment basis is laid for realizing the space active control of a multiple-degree-of-freedom space manipulator by a space station.

Description

technical field [0001] The invention relates to the technical field of positioning and vibration control of flexible structures, in particular to a multi-camera-based space vibration characteristic analysis device and method for a flexible arm. Background technique [0002] With the rapid development of today's aerospace industry, human beings are increasingly demanding the efficiency of space exploration. The rapid delivery of space materials has a huge impact on the maintenance of spacecraft and the food supply of space station staff. After the space shuttle reaches the target space station , Due to factors in the space environment, the docking of the space shuttle and the space station is very difficult, which results in a very limited efficiency of material delivery. The originally very simple docking work has become very difficult, and may even cause serious delays in material delivery. The successful development and use of the space robotic arm has almost fundamentally...
