Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a three-degree-of-freedom conversion system and method for different signal antennas in a vacuum environment. Background technique [0002] In the environmental simulation test of the vacuum subsystem of the space plasma environment simulation and research system, in order to realize the microwave transmission measurement of different working frequency bands, it is necessary to accurately switch to the required frequency band antenna device. A set of conversion mechanism fixtures was designed before, but antennas with different working frequency bands need to be manually clamped. Because in a vacuum environment, manual installation not only destroys the vacuum degree, but also reduces the operation efficiency and destroys the accuracy of the installation position. At present, the conversion mechanism of different signal antennas in a vacuum environment is automated...
