Abstract

A large-load low-impact connection and separation device based on memory alloy drive, including: memory alloy drive assembly (1), unlocking transmission assembly (2), connection and separation assembly (3) and buffer capture assembly (4); memory alloy drive After the assembly (1) is energized, it overcomes the tension of the extension spring (6), drives the trigger shaft (10) to rotate, releases the limit on the first-stage swing arm (9), and rotates the first-stage swing arm (9) to release the restriction on the second-stage swing arm. (8), the secondary swing arm (8) rotates to release the limit to the main force transmission nut (17), and the main force transmission nut (17) rotates so that the force bearing rod (22) moves along the center of the guide seat (23). The hole moves linearly to realize unlocking and separation. The invention can realize firm connection, unlocking and separation between satellites and arrows, between satellites and loads, and has the characteristics of large load, low impact, high reliability and reusability.

Description

technical field [0001] The invention relates to a connection and separation device, in particular to a connection and separation device driven by memory alloy. Background technique [0002] In aerospace missions, the mechanism that realizes the connection and separation functions between the spacecraft body and components, between the cabins, between the spacecraft and the launch vehicle, and between spacecraft is called the connection and separation device. A key component in a load separation system. At present, most of the connection and separation devices used in the aerospace field are based on the principle of pyrotechnic action, that is, cutting, punching or pushing out the connecting parts through the impact force of the explosion to achieve separation. However, this kind of device has insurmountable shortcomings such as strong separation impact, obvious additional pollution and non-reusable. [0003] At present, the separation device using memory alloy as the driv...
