The invention provides an inner taper-angle magnetic liquid damping shock absorber with an elastic cushion and belongs to the field of mechanical engineering vibration. The inner taper-angle magnetic liquid damping shock absorber with the elastic cushion successfully solves the problem that an existing magnetic liquid damping shock absorber can not be applied to engineering practice due to various structure problems. The device comprises a left end cover (1), the elastic cushion (2), a shell (3), a left threaded check ring (4), a left locating permanent magnet (5), a left locating rod (6), a first energy consumption permanent magnet (7), a connecting rod (8), a second energy consumption permanent magnet (9), a right locating rod (10), a right locating permanent magnet (11), magnetic liquid (12), a right threaded check ring (13), a right end cover (14) and a vent groove (15). When vibration happens outside, the magnetic liquid moves along with the left locating permanent magnet (5), the first energy consumption permanent magnet (7), the second energy consumption permanent magnet (9) and the right locating permanent magnet (11), so that energy is absorbed, the left locating permanent magnet (5) and the right locating permanent magnet (11) enable frequency difference to be formed between a mass block and the shell (3) under the action of taper angles, and the damping efficiency is maximized.
Description
technical field [0001] The invention relates to an inner cone angle magnetic liquid damping shock absorber with an elastic pad, 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, e...
