Description
Technical field
The utility model relates to a kind of tall and slender structure damping control device that contains novel wire rope damper.
Background technology
The high vibration of tower body can make tower body produce serious bending, inclination, plate efficiency decline, causes keeping normal production run and causes serious economy loss.Lasting and violent vibration also can cause the excessive formation fatigue crack of tower body skirt STRESS VARIATION amplitude, causes the cracking destruction of equipment, even can cause personnel's injures and deaths, causes serious security incident.Chinese large-sized petroleum chemical enterprise build the coastal area in more, and process units often bears the effect of wind loads such as typhoon, and the tower that the wind induced vibration causes destroys more outstanding, and the wind induced vibration causes the accident of chemical tower damage of facilities repeatedly to take place.The construction period of petrochemical iy produced device reaches several years, wants just can put into production after vacant a period of time behind many device context installation in position.Do not have material in the vacant tower, the damping of wind induced vibration is different from equipment under the mode of operation, even carried out the anti-vibration design under the The reasonable operating conditions, the wind induced vibration also may take place during vacant and destroy in tower.Therefore, be a practical problem that needs to be resolved hurrily to the research of the high tower vibration equipment of inducing generation by wind and the research and development of vibration control apparatus.
Tuned mass damper (Tuned Mass Damper) is called for short TMD, is to add inertia mass on towering top of tower or position, top, and is equipped with spring and links to each other with agent structure (towering tower) with damper.The vibration frequency of tuned mass damper is near the frequency of main structure, control strategy is for using the purpose that minor structure and the resonance of the main structure control vibration shape reach dynamic absorber, and the energy that the application damping structure constantly consumes main structure and minor structure reduces the dynamic response of main structure.Application about the tuned mass damper that is used for the tall and slender structure vibration damping in the prior art is less, effectiveness in vibration suppression is also bad, and the many employings of the damping unit in existing tuned mass damper hydraulic damper in the form of piston, need regular maintenance and replacing, yet, for the purpose of safety, do not allow by work high above the ground damping unit to be overhauled and changes under a lot of situations, this problem has seriously restricted the promotion and application of tuned mass damper in actual engineering.
Summary of the invention
In order to overcome shortcomings such as the needs periodic replacement that exists when existing tuned mass damper is used for the tall and slender structure vibration damping and maintenance, safety factor are low, the utility model provides a kind of tall and slender structure damping control device that contains novel wire rope damper.
The technical solution adopted in the utility model is:
The tall and slender structure damping control device that contains novel wire rope damper, described damping control device is arranged on the top or the top of tall and slender structure, it is characterized in that: comprise annular mass, suspension arrangement and wire rope damper, described annular mass hangs on the top or the top of described tall and slender structure by described suspension arrangement, be evenly equipped with a plurality of described wire rope dampers between the inwall of described annular mass and the outer wall of described tall and slender structure, described wire rope damper one end is connected on the described annular mass, and the other end is connected on the outer wall of described tall and slender structure by backing plate.
Further, described suspension arrangement comprises by backing plate and is fixed on a plurality of cantilevers on the outer wall of described tall and slender structure that described cantilever is along the circumference uniform distribution of tall and slender structure outer wall; Described cantilever suspends described annular mass in midair by suspension cable.
Further, described suspension cable upper end is connected with described cantilever by double-screw bolt, nut, washer sets component, and the lower end is connected with a plate by double-screw bolt, nut, washer sets component; Described junction plate is connected with a welded plate by double-screw bolt, nut, washer sets component, and described welded plate is welded on the inwall of described annular mass.
The beneficial effects of the utility model are embodied in: by the damping action of mass damper, can effectively reduce the oscillation intensity and the stress level of tall and slender structure; Adopt the wire rope damper of making by stainless steel, anti-corrosive alloy material fully that damping force is provided, can under various adverse circumstances, use for a long time and need not replacing and keep in repair.
