Description
Technical field
The utility model belongs to civil engineering and mechanical engineering technical field, relates to a kind of inner-wall extrusion friction type shape memory alloy twisting sinker.
Background technique
Traditional earthquake resistant 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 do not satisfy the requirement of Security, 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 and corrosion resistance are ubiquitous problems in the present sinker.Easily aging as viscoelastic damper, the maintenance of viscous damper, the reliability of frcition damper when long-term use the, the plasticity residual deformation of mild steel damper etc.
In addition, a large amount of seismic demage analysis show no matter many engineering structures (are symplex structures, or non-symmetry structure) destruction is produced by torsional vibration, and often earthquake is comparatively serious, and particularly the tall 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 torsional 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 torsional vibration; The 2nd, the center of mass and the center of rigidity of structure do not overlap, and the inertial force that acts on center of mass 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 torsional 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, superelasticity 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 torsional vibration and have important practical significance.
Summary of the invention
The utility model provides a kind of inner-wall extrusion friction type shape memory alloy twisting sinker, its objective is that solving existing passive damping device has residual deformation, poor durability, only has problems such as single direction damping capacity and energy dissipation capacity be limited.
The technical solution of the utility model is as follows:
The inner-wall extrusion friction type shape memory alloy twisting sinker mainly is made up of the marmem semi-circle rib and the steel flange of outer steel cylinder, interior steel cylinder, surperficial frosted.Main technical schemes is: arrange the thin-walled marmem semi-circle rib of ten groups of surface band frosteds symmetrically along the outer periphery of the interior steel cylinder that is connected with upper flange, along the thin-walled marmem semi-circle rib of radially arranging ten groups of surface band frosteds the interior week of the outer steel cylinder that is connected with lower flange symmetrically; Surperficial frosted thin-walled marmem semi-circle rib size on the inside and outside steel cylinder is consistent, and mutual interval straggly is arranged; 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 takes place in upper and lower flange, friction energy-dissipating when the surperficial frosted thin-walled marmem semi-circle rib on the inside and outside steel cylinder will push power consumption and mutual motion, these two-part will provide powerful antitorque commentaries on classics energy dissipation capacity jointly, to suppress structure or member torsional vibration planar; When vibration finished, because the semi-circle rib is to be made by marmem, so this sinker will automatically restore to initial position.
Effect of the present utility model and benefit are embodied in and have overcome other dampers shortcomings such as residual deformation, poor durability and energy dissipation capacity be limited are arranged, outstanding advantage is to utilize the mutual extrusion of super-elastic shape memory alloy to consume energy jointly with mutual friction mutually, 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.The inner-wall extrusion friction type shape memory alloy twisting sinker makes torsional resistance design more convenient, practical, will be widely used in civil engineering and mechanical engineering technical field.
