Abstract

The invention provides a multifunctional star arrow adapter which comprises an upper port, a lower port and a plurality of damp rods, wherein the upper port is used for connecting a satellite, and the lower port is used for connecting a carrier rocket. The star arrow adapter is mounted between the satellite and the carrier rocket, so that the thrust supplied by the rocket can be transferred, a structure bearing function can be achieved, a vibration isolating function can be achieved, and various vibrations and impact loads transferred from the rocket to the satellite can be isolated or reduced in a launching process, so that the dynamic environment of the satellite can be effectively improved, and the protection for the satellite can be realized. The multifunctional star arrow adapter is integrated with bearing and vibration isolating functions, is light in weight, is free from external energy supply and is suitable for aerospace engineering application.

Description

technical field [0001] The invention relates to the technical field of passive vibration isolation for satellites, in particular to a multifunctional star-rocket adapter. Background technique [0002] During rocket launch, a variety of dynamic loads, such as low-frequency vibration caused by rocket engine thrust pulsation, turbo pump, etc., stage separation, engine ignition and shutdown, and explosion of pyrotechnics, etc., will produce sudden load shocks, resulting in Structural damage or destruction of electronic devices and mechanical devices of satellites. Compared with the vibration environment when the satellite is in orbit, the vibration environment during the launch process is more severe, which is the main reason for the failure of the satellite. [0003] To solve this problem, the current general practice is: (1) strengthen the structure of the satellite, and take local vibration isolation measures for sensitive parts; (2) add a set of vibration isolation system b...
