Description

TECHNICAL FIELD

[0001] The present application relates to a co-cured integrated heat insulation and vibration reduction structure and a forming method thereof, and belongs to the technical field of heat insulation and vibration reduction of satellite sensitive components. BACKGROUND

[0002] With the deepening application of space remote sensing information technology in the development of national economy, environment and disaster monitoring, scientific research and military field, the resolution and control accuracy of space optical remote sensing satellites are improved year by year. The micro-vibration generated by flywheel and other moving parts and the thermal stress generated by temperature change of the satellite platform will affect the pointing accuracy of the satellite, and even affect the imaging quality of the load. Therefore, it is urgent to isolate the micro-vibration of the satellite platform and the heat conduction, so as to make the optical load in a good imaging environment, and obtain a clearer remote sensing image and more accurate positioning.

[0003] In order to ensure the vibration reduction effect of the flywheel and other disturbance components and the heat insulation effect of the platform under high and low temperature changes, two solutions are generally adopted. One is to adopt independent solutions for the above two problems respectively, but since the heat insulation and vibration reduction schemes are designed separately, there is a large design redundancy, which causes the mass and volume to be too large, and increases the launch cost. The other is the traditional integrated heat insulation and vibration reduction structure based on "convex" damper and heat insulation pad, which is assembled by a relatively simple functional component in series, and realizes integration in assembly, but must be used in pairs, which leads to poor mechanical environment adaptability, easy to cause system functional failure, and cannot realize the unified optimization distribution of the double targets of heat insulation and vibration reduction in design.
