Abstract

The invention discloses a separating device with a buffering structure. The separating device comprises a main body component, a separating component, pull rods and a pull rod cutting mechanism, wherein the pull rods are connected with the main body component and the separating component and press the main body component on the supporting surface of the separating component. A satellite is provided with a flange, and the ends, connected with the main body component, of the pull rods penetrate from one side of the flange and are locked through fasteners on the other side of the flange. The separating device is characterized in that buffering parts are installed on the side, with the fasteners fixed, of the flange, directly face the ends of the pull rods and are used for preventing half broken pull rods from exiting from the flange. The invention further discloses a satellite and rocket separating device with the buffering structure. According to the invention, the buffering parts are arranged at the ends of the pull rods for absorbing impact generated when the pull rods are broken, a separating buffering device is fixed through a pure mechanical structure, the shock absorbing and buffering effect is remarkable, the structure is simple, installation is convenient, the work is stable, and the development cost is low.

Description

technical field [0001] The invention relates to the technical field of separation and buffering of aerospace vehicles, in particular to a separation device with a buffer structure and a star-arrow separation device. Background technique [0002] A large number of pyrotechnic separation devices are used on spacecraft, such as explosive bolts, unlocking bolts, pin pullers, separation nuts, cutters, etc., to perform interstage separation, release part components, start or close some subsystems, and star-rocket separation , Sun wing deployment and other key actions. [0003] The pyrotechnic separation device uses the high-pressure gas generated by the explosion of the pyrotechnic product carrying the impact as the power, and the action is accompanied by the release of structural preload and structural impact. These loads are transmitted to various parts of the spacecraft through the structure in the form of stress waves, which will cause The severe instantaneous impact response...
