Embodiment Construction
[0039] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0040] Such as figure 1 and figure 2 As shown, a marine large-load low-frequency vibration isolation device of this embodiment includes a cylinder 4 with an open end, a support frame 1 is installed through the cylinder wall of the cylinder 4, and the end of the support frame 1 located inside the cylinder 4 is installed. There is a steel wire rope 3, and the steel wire rope 3 is spirally wound between the support frame 1 and the inner wall of the cylinder body 4; a piston block 6 sliding along it is installed inside the open end of the cylinder body 4, and the piston block 6 and the cylinder body 4 jointly form a A closed cavity filled with a shear thickening fluid 2 .
[0041]Through the combined vibration isolation structure of "steel wire rope + shear thickening fluid (STF) + piston block", the structural load-bearing function and fri...
