Embodiment approach

[0019] The shape memory alloy superelastic damper for cables, cables and slender rods of the present invention is composed of shape memory alloy wire and shape memory alloy wire fixing device. The damper is composed of end flange, outer steel pipe, inner steel pipe, shape Composed of memory alloy wire, there are two end flanges, and each end flange is composed of the upper half disc 2 of the end flange and the lower half disc 1 of the end flange. A central hole is provided in the center, and an end flange light hole 4 is provided on the circumference of the end flange. Both ends of the steel pipe; the inner steel pipe consisting of the upper semicircle 6 of the inner steel pipe and the lower semicircle 7 of the inner steel pipe is located in the center of the outer steel pipe, and the two ends of the inner steel pipe pass through the middle hole of the end flange respectively; on the outer wall of the inner steel pipe inside the outer steel pipe There are two internal disks co...

Abstract

A superelastic marmem damper for cable, rope and slent rod used for anti-earthquake purpose is composed of external steel pipe, two flange at both ends of external pipe, internal steel pipe, two internal disks on internal steel pipe, marmen wires passing through the holes on said internal disks, and fixtures for fixing the both ends of each marmen wire.

Description

technical field [0001] The invention relates to a device for anti-vibration (shock) and vibration reduction (shock) of civil engineering, and belongs to the technical field of vibration-damping device manufacture. Background technique [0002] Under loads such as wind and earthquakes, the lateral vibration displacement of cables, cables, and slender rod members in structures such as bridges is often relatively large in the direction perpendicular to their length (axis). It is an effective means to use dampers to suppress the vibration of cables, cables, and slender rods. The currently used dampers for cables, cables, and slender rods can effectively provide unidirectional damping, that is, they can effectively suppress the vibration of cables, cables, and slender rods. The lateral vibration displacement of the long rod in a certain plane (the plane includes the axis of the cable, cable, and slender rod) has a weak suppression effect on the lateral...
