Description
Technical field
This utility model relates to a kind of double stage clip cylinder radial inflow friction-changing dampers with complex damping feature, can be applicable to engineering structure vibration damping and controls, belongs to vibration control technology field.
Background technology
The damper that engineering structure vibration damping and vibration isolation field use can be generally divided into velocity correlation type and the big class of displacement relationship type two at present, and displacement relationship type antivibrator mainly includes the various metal dampers utilizing Plastic Deformation of Metal Materials to consume energy and all kinds of frcition dampers utilizing scraping mechanism to consume energy；Velocity-dependent damper currently mainly includes utilizing viscous fluid to pass through the viscous damper that damping hole produces damping force dissipation energy and the viscoelastic damper utilizing viscoelastic material plasticity ability to consume energy.Most of displacement relationship type antivibrators have the clear and definite damping force threshold value starting power consumption, when antivibrator stress is less than this threshold value, antivibrator provides elastic stiffness, do not produce energy expenditure, after its stress exceedes this threshold value, antivibrator enters yield situation or Frictional Slipping state, starts dissipation energy, but its damping force is the least with the growth deformed or no longer increases.From this view, displacement relationship type typically requires and sets its deformation condition playing power consumption effect, when deforming less than setting value, antivibrator does not play power consumption effect, and when deformation is much larger than setting value, due to less to the growth of damping force, its additional equivalent damping ratio will reduce with the increase of deformation, only can provide intended additional damping ratio near deformation amplitude setting.Viscous damper then can provide different damping forces and energy expenditure with velocity variations, speed is the highest, damping force is the biggest, consumed energy is the most, presence bit does not moves relationship type Threshold, thus in the vibration damping of engineering structure controls use displacement the to be more than relationship type of viscous damper.The but machining accuracy of viscous damper and seal request displacement to be significantly larger than relationship type, this causes its cost to be also significantly larger than general displacement relationship type, and comprehensively its cost performance is not so good as the latter.But at some in particular cases, viscous damper has the advantage that some displacement relationship types do not possess, and can not substitute with displacement type antivibrator under normal circumstances.Such as TMD vibration-proof structure system, do not obtain the damping effect of optimum, there is optimal value in the damping ratio of TMD minor structure, and its amplitude is the most uncertain, it is substantially not all right for using displacement relationship type: if selecting a too high damping force threshold value, TMD can be caused can not to start in good time and lose frequency adjusting damping effect；Select too small rising to slide power threshold value, there will be again energy dissipation capacity deficiency defect, cause TMD to control poor effect under big amplitude effect.Thus in current TMD vibration damping engineer applied, be the most all to use viscous damper to provide damping force.It addition, conventional friction antivibrator needs pre-add friction direct stress, frictional interface frictional behaviour under being chronically at high-stress state can change.

Further, antivibrator left end sleeve outer baffle block and middle slip axle right end plate are connected in structure.
Further, during original state, without precompression between described wedge shape sliding friction block and friction sleeve, i.e. contact stress is zero.Therefore antivibrator need not sliding power when loading, this advantageously ensures that the stable performance of frictional interface.
Further, the compression spring and the friction component that are positioned at cavity two ends are at least a pair.The damping force that the tonnage that can realize according to actual needs exerting oneself is bigger and different.
Further, the compression counter-force of described compression spring is more than the frictional force between wedge shape sliding friction block and friction sleeve rubbing surface.
