The invention belongs to the field of mechanical engineering vibration, and relates to an outer taper angle magnetic liquid damping absorber successfully solving the problem that due to multiple structure problems, an existing magnetic liquid damping absorber cannot be applied in the actual project. The absorber comprises a left shell (1), magnetic liquid (2), a left positioning permanent magnet (3), a left positioning bar (4), a first energy consumption permanent magnet (5), a connecting bar (6), a second energy consumption permanent magnet (7), a right positioning bar (8), a right shell (9), a right positioning permanent magnet (10) and a ventilation groove (11). When the outside vibrates, the magnetic fluid moves along with the left positioning permanent magnet (3), the first energy consumption permanent magnet (5), the second energy consumption permanent magnet (7) and the right positioning permanent magnet (10) so as to absorb energy, the frequency difference is formed between a mass block and the left shell (1) and the mass block and the right shell (9) through the taper angle action via the left positioning permanent magnet (3) and the right positioning permanent magnet (10), and the vibration reduction efficiency is maximized.
Description
technical field [0001] The invention relates to an external cone angle magnetic liquid damping shock absorber, which is suitable for vibration reduction of long and straight objects in spacecraft. Background technique [0002] The magnetic liquid damping shock absorber is a passive shock absorber with high sensitivity to inertial force, and has the advantages of simple structure, small size, large energy consumption and long life. Due to the special operating environment of the spacecraft, its own volume, weight and energy are limited to a certain extent, so the magnetic liquid damping shock absorber is very suitable for the low-frequency, small-amplitude vibration reduction of long and straight objects in large spacecraft, such as the solar energy of the space station. At the same time, it also has broad application prospects on the ground, such as vibration reduction of high-power antennas up to 100 meters long, vibration reduction of precision balances, etc. However, the...
