The world in which we live is a "vibrating" world, which is one of the most common natural phenomena we have. For example, mechanical vibrations caused by engine operation; when the automobile runs on a road, the vibration is caused by uneven road surface; vibration of the aircraft caused by the airflow; vibration of the bridge structure under the action of the vehicle; the vibration of the flexible cable structure under the action of wind load, and the like, even the earthquake belongs to the phenomenon of vibration (shock). Many vibrations are harmful, for example, mechanical vibrations produce noise; jolting is generated by the vibration of automobiles and airplanes, so that people feel uncomfortable; the structure vibration can generate fatigue damage, and the service life is shortened; the earthquake directly causes loss of lives and properties of people. Since the twentieth century, mankind has continuously searched for various vibration (shock) control technologies, and has successively invented and created various products and technologies for vibration isolation (shock), energy dissipation and shock absorption, and a steel wire rope damper is outstanding among them.

The steel wire rope damper is a general name of a damper taking a steel wire rope as a damping element, and energy is dissipated by changing the configuration of the steel wire rope and generating friction among steel wires wound with each other. There are various forms of wire rope dampers, such as: a bar-shaped steel wire rope damper, a ring-shaped steel wire rope damper, a drum-shaped steel wire rope damper, a butterfly-shaped steel wire rope damper, an arch-shaped steel wire rope damper and the like. The steel wire rope damper takes a steel wire rope as a damping element, and dissipates energy through friction between steel wires which are mutually wound, but in some cases, the steel wire rope damper is required to have a large damping ratio and strong energy dissipation capacity, so that the requirement cannot be met only by the friction energy dissipation between the steel wires.
