Flexible supporting system for remote sensing satellite whole-spacecraft transport

Abstract

The invention discloses a flexible supporting system for remote sensing satellite whole-spacecraft transport. A remote sensing satellite adapter is installed on a vertical structure of an L-type support in a thread connection mode, an auxiliary supporting structure is arranged on a horizontal structure of the L-type support and used for supporting a remote sensing satellite, a satellite supporting rod used for supporting the remote sensing satellite is supported at the upper end of an S-type weighing sensor, the lower end of the S-type weighing sensor is arranged on a guide assembly, the guide assembly is sleeved with a spring assembly, the lower end of the guide assembly penetrates through a hole in a guide plate, the spring assembly is compressed to move under the pressure action generated after the remote sensing satellite is installed, the upper ends and the lower ends of two sets of height adjusting rods are screw rods, the height adjusting rods are connected with the guide plate and a packaging box connecting assembly to adjust the height of the portions, supporting the remote sensing satellite, of the height adjusting rods, the height adjusting rods are locked through nuts on the adjusting rods after being adjusted to a proper height, and the packaging box connecting assembly is directly connected with the horizontal structure of the L-type support in a thread connection mode.

Description

technical field [0001] The invention belongs to the technical field of remote sensing satellite transportation, and in particular relates to a flexible support system which can be used for space vehicle whole-satellite transportation, with adjustable preload, controllable maximum support force and real-time display of support force. Background technique [0002] After the remote sensing satellite completes all the work in the AIT (assembly, integration, test) stage in Beijing, it needs to be transported to the launch site for the final work before launch. Remote sensing satellite transportation is an important part of its development process. As the size of remote sensing satellite payload equipment becomes larger and larger, the restrictions on the height and direction of the transportation process must require remote sensing satellites to be transported at the entire satellite level. [0003] Whole-satellite transportation puts forward higher requirements on the structural...

AI Technical Summary

Problems solved by technology

At present, there are two main types of supporting structures during whole-satellite transportation: the first one is the L-shaped bracket and adapter structure, the large cantilever structure of the satellite during the whole-satellite transportation, and it is easy to cause the connection structure between the satellite and the adapter during the transportation process. damage, and eventually lead to the failure of the satellite development process; the second is to add rigid auxiliary supports on the basis of the first structure. The rigid auxiliary supports can improve the stress state of the connection structure between the satellite and the adapter, but because its initial support force cannot setting, the maximum support force cannot be controlled, which can easily cause damage to the auxiliary support point of the satellite, and eventually lead to the failure of the satellite development process
