The satellite structure of satellite and the rocket vibration isolation.
Background technology
Satellite Product, at launching phase, can be affected by various vibrations, shock loading, excessive
Vibration, shock loading can directly result in destruction or the inefficacy of product on satellite.Its Satellite institute
The Main Load source being subject to is oscillating load, the rocket motor produced in rocket engine running
The shock loading that machine stage separation, the satellite and the rocket separate, this vibration, shock loading are tied by rocket
Structure is delivered to satellite-rocket docking face, is input to satellite body with the form of basic excitation, causes satellite
The structural vibration of product.Existing technology can't well solve vibration transmission between the satellite and the rocket
Problem, typically just by improve satellite structure intensity improve its vibration bearing capacity, this
To a certain extent it can be avoided that vibration, the structural failure that brings of shock environment, the result brought is but
It is that satellite structure weight, design cost are continuously increased.
Summary of the invention
For solving above-mentioned problems of the prior art, it is an object of the invention to provide one
