The invention discloses a two-dimensional magnetic liquid vibration absorber with a non-linear energy trap, comprising four vibration damping units in the directions of two moving
degrees of freedom, and its structure is composed of a casing, a dynamic
mass and a
stator; wherein, the casing is composed of Left end cover, coil lead inlet, cylindrical shell, heat dissipation hole, right end cover, coil lead outlet, sealing ring; dynamic
mass consists of left end nut, permanent
magnet ring, magnetic conductive block, permanent
magnet ring cage, right end nut, micro-nano It is composed of
magnetic composite fluid; the
stator is composed of a coil cage, a coil winding and a
copper coil; the guide component includes a left limit block, a guide shaft, a right limit block and a
lubrication groove. Based on the second type of suspension characteristics of the magnetic liquid, the invention realizes the vibration-targeted
energy transfer between the nonlinear energy trap and the flow pipeline, and finally dissipates the vibration energy of the flow pipeline through the
viscosity of the magnetic liquid.
