Abstract
A multi-dimensional hyperelastic shape memory alloy damper is a damping control device which is used in the technologies of civil construction and mechanical engineering. It is characterized in that: the damper is mainly composed of shape memory alloy thread, internal and external steel containers. The internal and external steel containers are coaxial and the shape memory alloy threads distribute level symmetry along the circle radial of the steel containers. The shape memory alloy threads penetrate into the external steel container and out of the internal steel container, and their ends are fixed on the internal and external steel containers separately. The threads are pulled to the midpoint of its hyperelastic platform by the prestrain of the adjustable screws and nuts. The plane motion of the internal steel container relative to the external steel container causes the elongation and shortening alternative change of the threads to provide stable damping force and large energy dissipation force. Its effects and advantages are: it has passive energy dissipation effect on any direction in the flat and functions of vibration damping and reduction on vertical and torsion direction. It can realize the multi-dimensional passive control of the structure.
Description
Technical field
The invention belongs to civil construction and mechanical engineering technical field, relate to a kind of damping control device, especially planar any direction performance passive energy dissipation effect has vertical and the vibration damping of torsional direction and the damper of reset function simultaneously concurrently.
Background technology
Good passive control device can effectively suppress the vibratory response of engineering structures, guarantees the safety and the applicability of structure.Passive energy dissipation device commonly used, as viscoelastic damper, viscous fluid damper, frcition damper, low-yield metal damper etc., have some limitation: the maintenance of aging and endurance issues, long term operation stability problem, Qiang Zhenhou and replacement problem etc.Marmem has special shape memory effect and superelastic effect as a kind of new function material that has perception and driving force concurrently.By the damper that marmem is made, have that recoverable deformation is big, damping capacity is strong and durability, anticorrosive, advantage such as fatigue resistance good, maintenance cost is low.
The response under random load effects such as earthquake, wind and mechanical oscillation of engineering structures or member is at random, and one of performance is exactly the randomness of vibratory response direction.The marmem damper of developing only has the passive energy dissipation ability of single direction usually at present, the difficult multidimensional Passive Control that realizes in the engineering own.
Summary of the invention
For implementation structure multidimensional Passive Control, the invention provides a kind of damper of multi-dimensional superelastic shape memory alloy, this damper not only has the passive energy dissipation ability of any direction in the plane, has the vibration damping and the reset function of vertical and torsional direction simultaneously concurrently.
The technical solution used in the present invention is: damper of multi-dimensional superelastic shape memory alloy mainly includes super-elastic shape memory alloy wire, interior steel cylinder, outer steel cylinder.Interior steel cylinder is coaxial with outer steel cylinder.Eight groups of shape-memory alloy wires are along steel cylinder circumference radial level symmetric arrangement, and promptly shape-memory alloy wire is penetrated by the hole of outer steel cylinder one side, passed by the hole of the corresponding side of interior steel cylinder, and its two ends are fixed on outer, interior steel cylinder; Shape-memory alloy wire is conditioned screw rod and the adjusting nut prestretched strain mid point to its super-elasticity platform.Interior steel cylinder is separately fixed at different structure or structure different component place with outer steel cylinder.When interior steel cylinder planar moves with respect to outer steel cylinder, interior steel cylinder is drawing shape-memory alloy wire and is partly extending and the alternately variation of part shortening ground, thereby stable damping force is provided and consumes big energy, to suppress the vibration of any direction in structure or the member plane.In addition, vertical displacement also can take place with respect to outer steel cylinder and reverse in interior steel cylinder, because shape-memory alloy wire is in extended state all the time in this vibration processes, so this damper has the vibration damping and the reset function of vertical and torsional direction again.
Effect of the present invention and benefit are: damper of multi-dimensional superelastic shape memory alloy, be used for civil construction and frame for movement, and utilize the super-elasticity hysteretic characteristic of marmem, consume vibrational energy, reduce structural vibration response, realize Passive Control.The outstanding advantage of this damper shows planar that any direction has the passive energy dissipation ability, has the vibration damping and the reset function of vertical and torsional direction simultaneously concurrently.This damper damping capacity is strong, recoverable deformation big, have anticorrosive preferably, fatigue resistance, and maintenance cost is low, simple structure, easy for installation.
