Novel flywheel support structure for spacecraft

Abstract

The invention discloses a novel flywheel support structure for a spacecraft. The novel flywheel support structure for the spacecraft comprises a first mounting part, a main bearing structure, and a second mounting part. The flywheel support is designed according to the design concept of structural optimization, and allows for light weight of a flywheel while having better performances than the original design performances. The flywheel support provides moving parts, such as reaction flywheels, momentum wheels and torque compensation wheels, with stable mounting base, guarantees safety and reliability of crafts in satellite launching phase and orbiting respectively, can also satisfy heat transfer requirement and mechanical conditions for controlling subsystem flywheels (or reaction momentum wheels and torque compensation wheels) in operation, has the advantages of light weight, simple structure and low manufacturing cost and is highly universal.

Description

technical field [0001] The invention relates to a support mechanism, in particular to a novel flywheel support structure for spacecraft. Background technique [0002] With the development of aerospace technology, the contradiction between the capacity limitation of the vehicle and the increasing weight of the spacecraft has become increasingly prominent. The structural optimization design has become one of the inevitable trends in the development of spacecraft structure design, and the demand for the optimal design of the flywheel support structure has also followed. produce. The reaction flywheel, momentum wheel and torque compensation wheel are important components of the spacecraft attitude control system, which can be collectively referred to as flywheels. They are very sensitive to vibration and noise during operation, and the flywheel bracket must have good mechanical properties. Traditional flywheel brackets are often designed according to experience, and the design ...
