Embodiment 1

[0027] see Figure 1-6 , a shear type damping tube with vibration damping performance, comprising an aluminum alloy joint 1, a carbon fiber tube 2, a damping rubber layer 3, an aluminum alloy casing 4, and a steel spring tube 5, the upper section of the carbon fiber tube 2 and the The aluminum alloy joint 1 is bonded and connected, the outer side of the lower section of the carbon fiber tube 2 is connected to the inner side of the aluminum alloy casing 4 through the damping glue layer 3, and the inner side of the lower section of the carbon fiber tube 2 is connected to the steel spring The outer side of the tube 5 is adhesively connected, and the aluminum alloy casing 4 is connected to the steel spring tube 5 .

[0028] see image 3 , the aluminum alloy joint 1 includes a sleeve 12 and an ear piece 11, the ear piece 11 is connected to the top of the sleeve 12, and the outer side of the sleeve 12 is connected to the upper section of the carbon fiber tube 2 through an adhesive ...

Embodiment 2

[0034] The present invention also provides a vibration-damping adapter, which includes the shear-type damping tube with vibration-damping performance of Embodiment 1. The following is a preferred embodiment.

[0035] The damping adapter consists of an upper end frame, eight upper end frame joints, sixteen above-mentioned shear damping tubes, and eight lower end joints. The eight upper and lower end joints are distributed symmetrically in the circumferential direction, and each joint is connected to two damping tubes. tubes, each damping tube is cross-connected with the upper and lower joints. The upper end frame is fixedly connected with the launch vehicle, and the lower end joint is fixedly connected with the satellite. The vibration-damping adapter not only has good vibration-damping performance, but also has a good rigidity index, and can improve the mechanical environment of the satellite payload in the active flight section of the rocket.

Abstract

The invention provides a shear type damping tube having a vibration damping performance and a vibration damping adapter. The shear type damping tube comprises an aluminum alloy joint, a carbon fiber tube, a damping glue layer, an aluminum alloy bushing and a steel spring tube, wherein the upper section of the carbon fiber tube is in bonding connection with the aluminum alloy joint; the outer side of the lower section of the carbon fiber tube is connected with the inner side of the aluminum alloy bushing through the damping glue layer; the inner side of the lower section of the carbon fiber tube is in bonding connection with the outer side of the steel spring tube; and the aluminum alloy bushing is connected with the steel spring tube. Compared with the prior art, the vibration damping adapter, produced by the shear type damping tube having the vibration damping performance, has excellent vibration damping performance to restrain low-frequency vibration of satellite effective load of an active flight section of a carrying rocket, and has better rigidity to improve the mechanical environment of the satellite effective load at the active flight section of the rocket when being used for connecting the carrier rocket with a satellite.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a shear damping pipe and a shock absorbing adapter with shock absorbing performance. Background technique [0002] The dynamic load generated by the active flight phase of the launch vehicle is the main basis for the design of the mechanical environment of the satellite payload. Most of the damage and failure phenomena caused by the first launch of satellites are caused by the dynamic environment of the active flight section of the launch vehicle. During the development of domestic satellites, especially the satellite platform developed for the first time, it often happens that the satellite structure cannot pass the ground vibration test and the development cycle is extended, or in order to pass the ground vibration test, the structure is designed to be cumbersome, which greatly reduces the satellite structure. payload ratio. How to improve the mechanical environment of satellite pa...
