Buffer device

Abstract

The invention discloses a buffer device which comprises a flange plate, double-end bolts, a buffer cap and fastening parts. A through hole is formed in the center of the flange plate, and multiple screw holes are formed around the flange plate, wherein the distance between the screw holes and the center is equal. The unilateral section of the buffer cap is in a Z shape, cylindrical through holes matched with the screw holes in the flange plate are formed in a flange at the upper end around the center axis, a middle transition segment is of a thin-wall structure, and flange turnup edges are arranged at the lower end and used for being fixed with an effective load connecting structure. Each double-end bolt is of a cylindrical structure with threads arranged at the two ends, and the cylindrical structures at the two ends are inserted into the screw holes of the flange plate and screw holes of the buffer cap and achieve cooperation and fixing through the fastening parts. The necessity of the buffer device with the functions of impact attenuation, vibration buffer and concentrated force diffusion is sufficient, and the effective buffer function can be achieved during equipment connecting or fixing.

Description

technical field [0001] The invention relates to the field of mechanical structure connection, in particular to a buffer device applied to the connection and separation position of a payload and a carrying system Background technique [0002] At present, the point-type device based on the pyrotechnic separation nut has mature technology and high reliability, and has been widely used in the connection and separation between the payload and the delivery system. However, in this scheme, the working impact of the pyrotechnic separation nut is relatively large, which has a great impact on the payload, and even affects the use function of some instruments and equipment on the payload. It also contradicts the impact environment requirements of the increasingly high payload. Moreover, when the payload is launched into the orbit through the delivery system, the vibration environment to be experienced is relatively harsh.

However, the working impact of the pyrotechnic separation nut in this scheme is relatively large, which has a great impact on the payload, and even affects the functions of some instruments and equipment on the payload. It is also contradictory to the impact environment requirements of the increasingly high payload.

Moreover, when the payload is launched into orbit through the delivery system, it needs to experience a relatively harsh vibration environment. Generally, it is necessary to take additional shock absorption measures for the sensitive components of the payload, and the weight gain is more obvious.

In addition, the point connection method causes the load transfer between the satellite and the rocket to be a concentrated force load, which has high requirements for the strength and stiffness of the local structure of the satellite connection point and the diffusion of concentrated force
