Study on Mechanical Materials with Overview of Connection and Separation Devices

摘要

Different kinds of mechanical materials in connection and separation devices have been widely used in spacecraft engineering and keep on innovating and improving. Pyrotechnic and non-pyrotechnic devices have their own advantages and drawbacks and the application of new materials such as SMA (shape memory alloy) and low-melting point materials has become a new and striving issue. Different kinds of connection and separation devices and their prime mechanical materials will be presented in details in this paper.
