Description

technical field

[0001] The invention belongs to the technical field of metal material structure design and processing, and in particular relates to a light-weight vibration-isolating metal composite flywheel bracket and a preparation method and application thereof.

[0002] technical background

[0003] The flywheel assembly is an important component for stabilizing the attitude of spacecraft such as satellites. The flywheel bracket is the core component of the flywheel assembly, and its weight and vibration isolation performance have an important impact on the payload performance index of the spacecraft. Through material design and structural design, on the premise of reducing the weight of the flywheel support, raising the first-order vibration frequency of the flywheel support and reducing the magnification of the flywheel mounting surface are the main methods of flywheel support design.

[0004] The material of the existing flywheel bracket is mostly single magnesium allo...
