Abstract

The invention discloses an eccentric shearing type low-impact expansion pipe double-groove-plate separation device which comprises an explosive cable, filler, a flat pipe, an H-shaped separation plate, an upper end frame, a lower end frame, an upper fastening bolt and a lower fastening bolt. The H-shaped separation plate comprises an upper U-shaped groove, a lower U-shaped groove and a connectingarea; the upper U-shaped groove and the lower U-shaped groove are located in the upper side and the lower side of the connecting area respectively. The upper end frame and the upper U-shaped groove are installed in a butt joint mode and fastened through an upper fastening bolt. The lower end frame and the lower U-shaped groove are installed in a butt joint mode and fastened through a lower fastening bolt. The flat pipe is arranged between the lower end frame and the lower U-shaped groove; the flat pipe is hollow, and the explosive cable is arranged in a hollow cavity of the flat pipe; and thefiller is filled in a cavity between the flat tube and the explosive cable. Impact generated in the action process can be reduced while it is guaranteed that the structure has high separation reliability.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to an eccentric shear type low-impact expansion tube double-groove plate separation device. Background technique [0002] The inter-stages of the launch vehicle and between the launch vehicle and the payload are connected through a separation device, and the separation function is realized at a specified time, which is an important link in the whole rocket separation system. With the increase of payload dimensions and load mass of launch vehicles, satellites, and space stations, the number of point separation devices has greatly increased, which brings about the disadvantage of reduced reliability, which makes it unable to meet the use requirements. [0003] At present, the line separation device has been widely used. As a kind of line separation device, the expansion tube groove plate separation device not only has the advantages of strong bearing capacity, high connection rigid...
