The invention discloses a damping bracket for a flywheel tuning liquid damper. The damping bracket comprises an upwards-arched door part, wherein the lower end of the upwards-arched door part is in threaded connection with a cylindrical base, a liquid filled cavity is formed in the cylindrical base, a liquid filling hole is formed in the upper end of the liquid filled cavity and is provided with a screw cap with a sealing ring, and the liquid filled cavity is filled with internal-filled liquid. According to the damping bracket for the flywheel tuning liquid damper, the flywheel damping bracket for the tuning liquid damper is applied to a spacecraft domestically for the first time; due to simple structure and integrated design, high-precision machining process flows are not required; due to light weight, a high-frequency micro-vibrating part of a flywheel is effectively damped in case of guaranteeing effective rigidity; high-frequency micro-vibration part of the flywheel is subjected to effective attenuation; by using a liquid sloshing phenomenon, high-frequency micro-vibration of the flywheel is subjected to energy attenuation. The damping bracket is safe and effective and can achieve the rapid attenuation of vibration resulting from the rotation of the flywheel.
Description
technical field [0001] The invention relates to a vibration-damping support, in particular to a vibration-damping support for a flywheel tuning liquid damper. Background technique [0002] With the development of high-resolution satellites, improving the resolution of high-resolution satellites is the future direction of satellite system design and development. In order to make the spacecraft and the precision equipment it carries require a mechanical environment in the sense of ultra-static, to ensure the measurement accuracy of the instrument. Therefore, it is necessary to isolate, damp and suppress the high-frequency micro-vibration generated during the working process of the typical actuators of the spacecraft. During the process of sensitive payload imaging, satellite attitude changes affect the accuracy of payload imaging. The existing technology is still unable to guarantee the normal operation of some high-precision and high-stability devices on the satellite. There...
