Problems solved by technology
At present, the mass of micro-nano satellite separation devices with a mass of 1-50kg in foreign countries is relatively heavy, which will increase additional costs for satellite launches. In China, the development of micro-nano satellites is in its infancy, and the connection and separation technology for micro-nano satellites is still blank.

The invention provides a modular low-impact linkage type microsatellite separating unit which comprises a launching guide module, a locking module, a pre-tightening module and a release module which are installed on a bottom plate. One end of the pre-tightening module is connected with the locking module through a pressing rod, the other end of the pre-tightening module is connected with the release module through a pull rope, and a linkage mechanism is formed. The separating unit is composed of a plurality of modular units and is simple and compact in structure, and all degrees of freedom of a fixed object are completely limited. In addition, the linkage mechanism is formed by the locking module, the pre-tightening module and the release module, and motion transfer is smooth and convenient. A grooving bolt is expanded to be broken through the release module based on shape memory alloy, so that impacts on microsatellites in the release process are extremely small, and no influence is generated on the posture and stability control over a spacecraft body and separated objects.
Description
Technical field [0001] The invention relates to a separation device, in particular to a modular low-impact linkage type micro-satellite separation device. Background technique [0002] With the development of micro-nano technology, integrated integrated electronics and other technologies, as well as the innovation of satellite design ideas, miniaturization has become an inevitable trend in future satellite development. In 2013, small satellites launched globally accounted for more than 70% of the total number of launched satellites. In the future, the global annual demand for micro-nano satellites of 1-50kg will continue to increase. [0003] Traditional satellite separation mostly uses discretely distributed pyrotechnics point-type and docking frame-type package belt connection separation schemes. The former has a large separation impact and low synchronization indicators, while the latter has a large additional quality. Although the pyrotechnic device has a series of advantages ...
