Problems solved by technology

The solar wing hinge line driving characteristic test device can realize the installation of hinges, cables and other tested parts, and at the same time realize specific tension loading. The test device simulates the process of solar wing deployment and retraction, and tests the rotation angle and torque parameters in real time to obtain accurate and reliable results. Test data such as driving torque, frictional resistance torque and stiffness can improve the reliability and development level of space application equipment. At present, there is no dedicated testing device for the driving characteristics of the solar wing hinge line

Description

technical field [0001] The invention relates to a test device for driving characteristics of a solar wing hinge line, which belongs to the technical field of space application equipment. Background technique [0002] In order to ensure the reliable deployment of the solar wing on orbit and limit the impact load at the end of deployment within an acceptable range, it is necessary to control its driving torque margin. The calculation of the moment margin needs to use parameters such as the driving moment of the hinge (inter-plate hinge and root hinge), the resistance moment of the connecting cable, and the frictional resistance moment caused by the hinge line such as the tension of the locking ring. The solar wing hinge line driving characteristic test device can realize the installation of hinges, cables and other tested parts, and at the same time realize specific tension loading. The test device simulates the process of solar wing deployment and retraction, and tests the ro...
