Abstract

The invention discloses a dual-spreading solar wing vibration measuring device and method. The device comprises a dual-spreading solar wing, a vibration excitation mechanism and a vibration detectingmechanism; the vibration excitation mechanism is connected with the dual-spreading sun wing and is used for exciting the dual-spreading solar wing to generate vibration; the vibration detecting mechanism comprises two sets of binocular vision systems and two trusses; the two trusses are arranged in parallel from front to back; the two sets of binocular vision systems and two trusses are in one-to-one correspondence; and each set of binocular vision systems are arranged on the corresponding truss; the two sets of binocular vision systems are used to detect vibration detection marker point areason the front and rear upper surfaces of the dual-spreading solar wing. The two sets of binocular vision systems are arranged on two trusses arranged in parallel from front to back, the two sets of binocular vision systems are used to detect the vibration detection marker point areas on the front and rear upper surfaces of the dual-spreading solar wing, non-contact measurement of the dual-spreading solar wing can be achieved, and more accurate vibration information of the dual-spreading solar wing can be obtained.

Description

technical field [0001] The invention relates to a vibration measurement device, in particular to a vibration measurement device and method for double-deployed solar wings, belonging to the field of vibration measurement. Background technique [0002] In recent years, the complexity of the tasks undertaken by spacecraft has been increasing, and people have higher and higher requirements for its structure. On the one hand, it is required to increase the carrying capacity, and on the other hand, it is required to reduce the total mass of the structure. , flexibility, and large-scale development, great flexibility has become a major feature of modern spacecraft. Flexible structures widely exist in spacecraft, such as solar panel structures of satellites or space workstations, spaceflight wings, flexible robotic arms of space stations, large parabolic antennas, etc. From their structural characteristics, spacecraft with flexible structures can be divided into three categories : ...
