Description

technical field [0001] The invention relates to the technical field of antenna cable testing, in particular to a high and low temperature torsion torque testing device and testing method for planar unfolded antenna cables. Background technique [0002] For planar deployment antennas, due to the large number of inter-board cables and their large diameters, the resistance moment of the inter-board cables is the main resistance to be overcome during the antenna deployment process. In order to investigate the influence of the inter-board cable on the antenna deployment, it is necessary to know the mechanical properties of the cable at high and low temperatures. At present, the main methods for obtaining the torque value of the antenna inter-board cable are: [0003] (1) According to the type of cable and the number of cables, it is obtained through digital simulation analysis.

[0003] (1) According to the type of cable and the number of cables, it is obtained through digital simulation analysis. Using digital simulation can characterize the torque of the cable to a certain extent, but ignores the actual working conditions such as the thermal control coating state, binding state, and tightening torque of the cable. Due to the influence of the environment, it is impossible to truly, reliably and accurately grasp the performance parameters when the antenna is deployed;
