Under normal conditions, the magnetorheological fluid filled in the four groups of magnetic particle liquid flow grooves maintains a low viscosity, allowing the dynamic adaptive floating component to move flexibly. When the floating state needs to be adjusted, the micro-electrically controlled liquid shock absorber is started, and a variable magnetic field is generated through the built-in end electromagnetic coil, which acts on the magnetic particle liquid in the magnetorheological edge ring, instantly changing its rheological properties, and using the change in magnetic field intensity to increase or decrease the viscosity of the magnetorheological fluid, thereby controlling the movement resistance and response speed of the dynamic adaptive floating component inside the cylinder, effectively improving the floating performance of the floating cylinder and the stability of the load balance control, and being able to adapt to diverse operating requirements, reducing unnecessary mechanical wear, and extending the service life of the cylinder.

[0017] 2. In the present invention, by utilizing the shape memory effect of the memory metal edge ring in cooperation with the dynamic adaptive floating component, a stable or variable voltage micro-stimulation current is generated according to the hydraulic accumulator and the external current and voltage follower, so that the memory metal edge ring changes its shape, and the position of the sliding floating edge is indirectly adjusted to adapt to the load changes under different working conditions, and the adaptability and stability of the floating are further enhanced.

The floating hydraulic cylinder according to claim 2, characterized in that: A piston rod (20) is installed inside the cylinder (1), and a steering connection threaded component (9) is connected to the side of the piston rod main seal (2) and the piston rod (20) on one side, and a bearing component (13) is installed inside the steering connection threaded component (9).

6. The floating hydraulic cylinder according to claim 5, characterized in that: The front end of the piston rod (20) is provided with a stabilizing cup (14), and the outer side end of the piston rod (20) is provided with an anti-fouling and anti-wear buffer sleeve (19).

7. The floating hydraulic cylinder according to claim 6, characterized in that: A piston (18) is installed on the side of the anti-fouling and anti-wear buffer sleeve (19), and dustproof sealing rings (15) are installed on both left and right ends of the four groups of floating track slide grooves (17).

8. The floating hydraulic cylinder according to claim 3, characterized in that: A magnetic flow control line tube (11) is installed on the side of the control tube (8), and a magnetic field controller (12) is connected to the side of the magnetic flow control line tube (11).

9. The floating hydraulic cylinder according to claim 8, characterized in that: The magnetic field controller (12) monitors the vibration or displacement, analyzes and processes the vibration or displacement, and outputs a command. When the vibration or position displacement is greater, the command is transmitted to the inside of the magnetorheological edge ring (165), the magnetic particle liquid flow groove (21), and the four groups of permanent magnet array columns (166).
