Abstract: A seismically suspended isolation device is installed in a suspended configuration at a fixed end and comprises a first support module, a second support module, a first displacement suppressing module and a second displacement suppressing module. The first support module includes a first fixing element, a first moving element, and at least one first roller. The first roller is disposed between the first fixing element and the first moving element. The second support module includes a second fixing element, a second moving element, and at least one second roller. The second roller is disposed between the second fixing element and the second moving element. The first support module and the second support module are stacked together in an orthogonal manner, so that the seismically suspended isolation device generates motion in the first direction and the second direction when the seismically suspended isolation device subjected to an external force.

Abstract: A micro-nano fluid damper includes a sleeve, a piston assembly and a micro-nano fluid. The sleeve has an accommodating space. The piston assembly has a piston head and at least one piston rod. The piston assembly is movably disposed in the accommodating space. The piston rod extends out of the sleeve from a side of the piston head. The micro-nano fluid is filled between the sleeve and the piston assembly, and the micro-nano fluid flows in the accommodating space by the back-and-forth movement of the piston. When a shear strain rate of the micro-nano fluid is greater than 1s−1, an exponent of velocity of the micro-nano fluid damper is less than 1, and the micro-nano fluid has a shear thinning threshold and a shear thickening threshold.
