Description
Technical field
The utility model belongs to civil construction and mechanical engineering technical field, relates to a kind of damping control device, has the damper of vibration power consumption and reset function especially simultaneously.
Background technology
Marmem is a kind of new function material that has perception and driving force concurrently, has special shape memory effect and super bounce effect.Compare with the other materials damper 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.
In structure applications, the evaluation of damper function admirable is mainly reflected in two aspects: the one, what structure or member vibrated under the dynamic load effect reduces; The 2nd, structure or member reduce the back permanent set of shaking by force.More existing at present dampers that utilize the super-elasticity of marmem to develop, mainly be divided into two classes according to its function: a class is the energy-dissipating type damper, and full hysteresis loop is provided, and can consume a large amount of vibrational energies, but permanent set is big after the off-load; Another kind of is the restoration type damper, and its hysteresis loop is long and narrow, a little less than the energy dissipation capacity, but can restPose after the off-load.The power consumption and the reset function of marmem are combined, exploitation function admirable, super-elastic shape memory alloy damper simple in structure, the implementation structure Passive Control has important practical value.
Summary of the invention
For reduce structural vibration and shake by force after permanent set, the utility model provides a kind of energy-consumption resetting shape memory alloy damper, this damper has good passive energy dissipation and reset function simultaneously, and simple structure, is easy to install.
The technical solution adopted in the utility model is: energy-consumption resetting shape memory alloy damper, by super-elastic shape memory alloy wire, about outer steel plate, about in steel plate, guide peg, pull bar, sleeve, connecting rod, adjusting screw(rod), adjusting nut, locking nut and anchor clamps form.Outer steel plate is fixed on the guide peg, constitutes fixed frame with connecting rod; Interior steel plate is fixed on the variable cross-section pull bar, between have sleeve spacing, form sliding frame.Pull bar passes the outer steel plate of a side, so relatively moving between two frameworks can be taken place.Damper is connected with the structure pin by pull bar and connecting rod are terminal.
Power consumption---shape-memory alloy wire is divided into reset silk and power consumption silk by function in the damper that resets.The silk that resets is separately fixed on the inside and outside steel plate of both sides, and symmetric arrangement; When sliding frame relative fixed frame movement, the silk elongation of resetting of an opposite side with the direction of motion, and with the direction of motion mutually a flexing that resets of the same side deactivate, thereby good large deformation recovery capability is provided.The silk that consumes energy applies the mid point of prestrain to its super-elasticity platform by adjusting screw(rod) and adjusting nut, and a pair of power consumption silk connects steel plate in the outer steel plate in a left side and the right side, and another connects steel plate in an outer steel plate in the right side and the left side to the power consumption silk; Sliding frame is drawing two pairs of power consumption silks and hockets and stretch and retraction changes during work, forms full hysteresis loop, and stable damping force is provided, and consumes a large amount of vibrational energies.The silk that resets plays a role separately with the power consumption silk, makes damper have good passive energy dissipation and reset function simultaneously.
Effect of the present utility model and benefit are: energy-consumption resetting shape memory alloy damper, have good passive energy dissipation and reset function simultaneously, the Passive Control that is used for building and mechanical engineering technical field, can reduce structure or member vibration and shake by force after permanent set.This damper structure is simple, is easy to install, and has good anticorrosive and fatigue resistance, and maintenance cost is low.
