Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing whole-satellite vibration reduction and isolation have different requirements for vertical and lateral vibration isolation frequencies, especially the vibration isolation or vibration absorber does not allow the lateral torsional stiffness of the satellite support to be reduced, that is, the satellite does not need to be enlarged. For the problem of lateral swing in the fairing, a satellite overall vibration reduction and vibration isolation device is provided

Abstract

The present invention is overall satellite vibration reducing isolator and aims at solving the problem that the overall satellite vibration reducing isolator has different longitudinal and transverse vibration isolating frequencies and the requirement of no reduction in transverse torsional rigidity of satellite support. The present invention resolves the vibration caused by the carrier rocket into one transverse vibration component and one longitudinal vibration component for subsequent separated vibration reduction and isolation. The overall satellite vibration reducing isolator includes satellite connect member, vibration reducing and isolating mechanism and carrier connecting member. The present invention makes it possible to use precise elements in space craft and lower satellite launching cost via reducing vibration of satellite.

Description

technical field [0001] The invention relates to a vibration damping and isolating device. Background technique [0002] The dynamic environment in which a satellite is launched is the harshest. Therefore, ensuring that the satellite can not be damaged in the dynamic environment of the launch process is the main research direction of the current satellite structural strength design. Usually, the strength of the satellite itself is improved, but the quality of the spacecraft is increased, which increases the launch cost, and the increased quality is useless in the normal operation of the spacecraft in orbit. The satellite adapter is the connection part between the satellite and the launch vehicle. The existing satellite adapter is a section of conical shell structure with bolt holes at both ends to connect with the satellite connection interface and the vehicle connection interface respectively. The overall satellite vibration reduction and isolation device is a modification...
