Description
Technical field
The utility model belongs to civil engineering and mechanical engineering technical field, relates to a kind of internal collision-friction-deformation three-stage power consumption twisting energy absorber.
Background technology
Violent each time earthquake all can cause huge life and property loss to the mankind.Traditional seismic design is to resist geological process by the rigidity that strengthens building itself, promptly rely on structure itself to store and earthquake energy, to satisfy the structural seismic standard of setting up defences, this antidetonation mode lacks capacity of self-regulation, under uncertain geological process, usually can not satisfy the requirement of safety, the energy-dissipating and shock-absorbing technology provides a rational and effective approach for structural seismic.The damping technology of passive energy dissipating damper is relatively ripe, yet as a kind of passive control device, durability is a ubiquitous problem in the present sinker.Common viscoelastic damper is easily aging, the maintenance of viscous damper, the reliability of frcition damper when long-term use the, the plasticity permanent set of mild steel damper etc.
A large amount of seismic demage analysis show, the destruction of many engineering structuress (no matter be symmetrical structure, or unsymmetric structure) is produced by twisting vibration, and often earthquake is comparatively serious, particularly the highrise building of complex shape will be in case destruction will be caused enormous economic loss and casualties.Can draw from domestic and international actual earthquake experience, cause during earthquake that structure produces the reason of twisting vibration: the one, because the difference of moving between the particle of ground can make each part on ground not only produce translation component, and the component that rotates.This rotative component forces structure to produce twisting vibration; The 2nd, the mass centre and the center of rigidity of structure do not overlap, and the inertia force that acts on mass centre during earthquake will produce torsional moment to center of rigidity, force structure to produce the space oscillations that the coupling connection is reversed in translation.At mechanical engineering field, disadvantageous twisting vibration is very common especially.The sinker of developing only has axial passive energy dissipation ability usually at present, itself is difficult for the Torsional Vibration Control in the realization engineering.
Marmem is a kind of new function material, has shape memory effect, super-elasticity and fatigue-resistance characteristics.Utilize the passive sinker of the super elastic characteristics making of marmem can overcome the problems referred to above.Advantages such as this class sinker is compared with other dampers, has durability and corrosion resistance and good, and life cycle is long, and distortion is big and can recover.But existing marmem sinker mainly utilizes the damping characteristic of austenite shape memory alloy, and energy dissipation capacity is limited.
Therefore, a kind of sinker that antitorque rotational oscillation kinetic force, high damping characteristic is arranged and have runback potential energy power of exploitation is resisted earthquake disaster and mechanical engineering to civil engineering structure and is reduced disadvantageous twisting vibration and have important practical significance.
Summary of the invention
The utility model provides a kind of internal collision-friction-deformation three-stage power consumption twisting energy absorber, its objective is that solving existing passive damping device has permanent set, poor durability, only has problems such as axial vibration damping ability and energy dissipation capacity be limited.
The technical solution of the utility model is as follows:
Internal collision-friction-deformation three-stage power consumption twisting energy absorber mainly is made up of outer steel cylinder, interior steel cylinder, marmem space bar, interval steel plate and steel flange.Main technical schemes is: arrange 18 groups of trapezoidal interval steel plates symmetrically along the outer periphery of the interior steel cylinder that is connected with upper flange, along the interior week of the outer steel cylinder that is connected with lower flange radially arranging the 18 groups of memorial alloy of falling trapezoidal shape space bars symmetrically; Interval steel plate and the mutual layout straggly of marmem space bar; Be equipped with the steel chute on the upper and lower flange, can insert for outer, interior steel cylinder and slide; Sinker is fixed in the position that to reverse control by the bolt hole on the flange.
When relative twist motion took place upper and lower flange, the internal collision-friction-deformation three-stage power consumption will take place in steel plate and marmem space bar at interval, suppresses the twisting vibration planar of structure or member jointly.The energy dissipation capacity of this sinker is directly proportional with amplitude, when amplitude hour, each at interval in steel plate space separately with marmem space bar generation non-perfect elastic collision, reach the purpose that exchanges momentum and dissipation kinetic energy; When amplitude is big, steel plate will enter the clearance space on next door at interval, this process can with marmem plate generation friction energy-dissipating; And, will produce stronger restoring force, thereby reach the purpose that reduces structural vibration because the distortion of marmem plate in this process is bigger.
Effect of the present utility model and benefit are embodied in and have overcome other dampers shortcomings such as permanent set, poor durability and energy dissipation capacity be limited are arranged, outstanding advantage is that this three aspect of mutual internal collision-friction-deformation that makes full use of steel plate and marmem plate consumes energy jointly, has significantly improved the energy dissipation capacity of sinker; This damper recoverable deformation is big, have anticorrosive preferably, fatigue resistance, and maintenance cost is low, simple structure, easy for installation.Internal collision-friction-deformation three-stage power consumption twisting energy absorber makes torsional resistance design more convenient, practical, will be widely used in civil engineering and mechanical engineering technical field.
