Description

technical field [0001] The invention relates to a low-impact space docking sealing device docking performance test system, which belongs to the field of spacecraft space docking. Background technique [0002] All space powers, including my country, are developing a new generation of spacecraft space docking systems with typical technical characteristics such as low impact, high reliability, standardization, multi-functionality, light weight, high efficiency, and intelligence. Flexible docking, the impact load during the docking contact process is small, so the new generation of spacecraft space docking systems are collectively referred to as low-impact docking systems (the specific structure varies from country to country). [0003] Sealing is one of the main links in the spacecraft rendezvous and docking process. After the tracking aircraft and the target aircraft are aligned and tightened, the two docking systems are sealed, locked, and rigidly connected to form a sealed de...

Problems solved by technology

If the extrusion force of the butt joint sealing device is large, higher requirements will be placed on the tension force of the low-impact space joint system, which will have a greater impact on the overall performance and function realization of the low-impact space joint system; such as the adhesion between the joint seals Large force can lead to tearing failure of the sealing structure, and even cause the docking aircraft to be unable to separate
