The temperature control sliding rod comprises a signal receiver, a battery pack, a temperature control sheet, a honeycomb type memory alloy and a shell, the shell comprises an inner shell body and an outer shell body, the inner shell body is connected in the outer shell body in a nested manner, the signal receiver, the battery pack and the temperature control sheet are all arranged in the outer shell body and connected with the outer shell body, the battery pack is respectively connected with the signal receiver and the temperature control sheet and supplies power to the signal receiver and the temperature control sheet, the signal receiver is in communication connection with the temperature control sheet, the honeycomb type memory alloy is arranged in the inner shell body, one end of the honeycomb type memory alloy is connected with the temperature control sheet, and the other end of the honeycomb type memory alloy is connected with the inner shell body. The temperature control sliding rod is mainly used for a large-scale space truss structure.

Description

technical field [0001] The invention belongs to the field of aerospace, in particular to a temperature control slide bar based on a honeycomb memory alloy structure. Background technique [0002] A large-scale space truss structure generally refers to a space truss structure with a structural size of more than 50 meters. Due to the large size, it is limited by the envelope size of the launch vehicle fairing. accomplish. Therefore, parts materials such as uplink supply ball joints and connecting rods are mostly used, and they are obtained through the pre-launched robotic assembly system for on-orbit autonomous construction. The on-orbit autonomous assembly of this large-scale space truss structure has the following particularities: [0003] 1. The large-scale space truss structure is generally used as a support back frame for on-orbit space payloads such as megawatt-level solar power plants, high-power radio telescopes, and very long baselines, which requires large-scale sp...

Problems solved by technology

[0005]3. The on-orbit construction of large-scale spatial structures is still essentially the autonomous assembly of parts. As long as it is assembled, there will be assembly errors. Increase, the assembly error will gradually accumulate, thereby affecting the construction accuracy of the entire truss structure. When the accumulated error reaches a certain level, the original precision control requirements cannot be guaranteed only by means of eliminating gaps at the microscopic level;
