Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings.

[0041] In order to ensure the success of the launch mission, the launch vehicle development department puts forward more stringent anti-overload requirements for the micro-nano satellite structure, which increases the cost of satellite structure design, development and test verification. Therefore, in order to improve the mechanical environment of the micro-nano-satellite launch section and reduce the cost of satellite development, an efficient method is to add passive or active vibration isolation devices to the satellite-rocket adapter to reduce the vibration load acting on the satellite.

[0042] Such as figure 1 , 2As shown in , 3 and 4, a satellite arrow adapter device for vibration reduction of micro-nano satellites, including: star terminal adapter frame 1, center limit column 2 of vibration-damping pad, upper-end vibration-damping pad 3, vibration-damping pad ...

Abstract

The invention discloses a satellite and rocket adapter device used for micro / nano satellite vibration attenuation. Satellite and rocket mechanical interface adapting and satellite system level vibration attenuation are integrally designed, the satellite and rocket adapter device suitable for 1kg-50 kg-level micro / / nano satellite vibration attenuation can meet connection adapting of a circular ringtype micro / nano satellite unlocking mechanism and a rocket support and also has good vibration attenuation performance and anti-impact performance so that the mechanical environment of a micro-nano satellite launching section can be effectively improved; and meanwhile, according to the satellite and rocket adapter device, a set of simulated analysis and verification test flow with a complete system is formulated for optimization of appropriate rigidity of upper / lower anti-vibration pads, the optimization for the rigidity of the anti-vibration pads is formulated to meet the special environmentrequirement of aerospace application.

Description

technical field [0001] The invention relates to a satellite-rocket adapter device with vibration reduction, in particular to a satellite-rocket adapter device for vibration reduction of 1kg-50kg micro-nano satellites. Background technique [0002] Satellite vibration reduction / isolation technology has always been concerned by aerospace engineering circles in various countries. At present, a series of researches have been carried out on the whole satellite vibration isolator technology at home and abroad, including active control, passive control and active-passive integrated control. The research results have already had engineering applications for actual launch. At present, in the domestic aerospace field, passive vibration isolation is mainly adopted and applied to the improvement of the star-rocket adapter of the main star, and a good vibration reduction effect has been achieved. However, there is still a lack of relevant research and application experience in research ...
