Problems solved by technology

[0003] The technical problem to be solved by the present invention is that when the external vibration amplitude of the existing magnetic liquid damping shock absorber is greater than the gap between the shell and the permanent magnet, there will be a collision between the permanent magnet and the inner wall of the shell, causing the shock absorber to use Decreased service life affects vibration damping performance; permanent magnets are heavy and poor in processability

Abstract

The invention relates to a magnetic liquid damp shock absorber and belongs to the field of mechanical engineering vibration. The magnetic liquid damp shock absorber solves the problems that under the condition that external amplitude is larger than a gap between a shell body and a permanent magnet of an existing magnetic liquid damp shock absorber, the permanent magnet collides with an inner wall of the shell body and thus service life of the shock absorber is shortened and shock absorption performance is influenced. The permanent magnet is large in specific gravity and difficult to process to a required shape. A cylindrical permanent magnet of the magnetic liquid damp shock absorber is a rubber cylindrical permanent magnet (7). A wedge angle gasket (5) is arranged at the bottom inside the shell body (4) and a V-shaped included angle of the wedge angle gasket (5) faces upwards. The rubber cylindrical permanent magnet (7) absorbing magnetic liquid (6) is arranged in the shell body (4) and is magnetized along the axial direction. The axis of the rubber cylindrical permanent magnet (7) is perpendicular to a horizontal plane. The V-shaped included angle of the wedge angle gasket (5) is 60 degrees to 170 degrees. The gap between the inner wall of the shell body (4) and the rubber cylindrical permanent magnet (7) is smaller than or equal to the amplitude of shock absorption required by the shock absorber. The magnetic liquid damp shock absorber is simple, reliable, obvious in shock absorption effect and long in service life.

Description

technical field [0001] The invention belongs to the field of mechanical engineering vibration. Background technique [0002] Due to its high sensitivity to inertial force, large energy consumption, small size, simple structure, and long life, the magnetic liquid damping and vibration reduction technology has been gradually used in the aerospace field. The typical structure of the existing magnetic liquid damping shock absorber is as described in the patent application with publication number CN 102032304A. The shock absorber includes: an O-shaped rubber sealing ring, a housing, a magnetic liquid, a permanent magnet, and an end cover. The permanent magnet is placed in the casing, the magnetic liquid is adsorbed on the permanent magnet, the end cover and the casing are fixedly connected by bolts and nuts, and the O-shaped rubber sealing ring is used for sealing. When the vibration amplitude of the shock absorber is greater than the gap between the shell and the permanent magn...
