The invention provides an active adjustment mechanism for the tension force of a thin film antenna, comprising: a thin film antenna, a casing, a power source, a connector, a tension sensor and a controller; the connector is connected to the thin film antenna through the tension sensor, and the tension sensor is electrically connected to control the The device is used for real-time detection of the tension force of the thin film antenna and feedback to the controller. The power source is installed on the housing, the power source drives the connecting piece, the power source is electrically connected to the controller, and the power source receives the electrical signal sent by the controller after comparing the value transmitted by the tension sensor with the set value. The driving source drives the connecting piece to pull the film antenna to move, which is used to adjust the film tension to keep constant and maintain the shape and surface accuracy of the film antenna.
Description
technical field [0001] The present invention relates to the field of spacecraft mechanism adjustment technology, in particular, to an active adjustment mechanism for the tension force of a thin film antenna. Background technique [0002] Since the mid-1860s, with the rapid development of space science and technology, the demand for spaceborne antennas has increased day by day, and the requirements for various technical indicators have become higher and higher, and the diameter of satellite antennas has become larger and larger. Due to the limitation of the carrying space of space vehicles (launch vehicles or space shuttles), satellite antennas are forced to develop in a deployable direction. Film antennas have gradually become the best choice for low-frequency antennas due to their high storage ratio and light weight. [0003] The so-called film wire mainly refers to the inflatable expandable antenna. Its working principle is as follows: first, the paint that can reflect el...
