Description
Technical field
The utility model relates to the damper technique field, the damper of specifically a kind of friction-viscous comprehensive function.
Background technique
Vibration is the physical phenomenon that extensively is present in building, the machinery, and in the manufacturing and designing of electromechanical equipment, electronic instrument and ocean platform that can proper functioning under complex environment, vibration control is one of factor of considering of emphasis.Vibration has become restriction engineering design performance, reliability and the key factor in life-span.Therefore, vibration control is most important in machinery and structure Design.Vibration control is the acting in conjunction that utilizes control mechanism and vibrational structure, the transmission of the vibrational energy between control structure, thereby the destruction that prevents equipment effectively.Whether the structure control peace needs the signal of external energy and excitation and structural response, can be divided into Passive Control, ACTIVE CONTROL, half ACTIVE CONTROL and mix control, develops intelligent control rapidly in addition in addition recently.Passive Control is that a kind of control system does not need extraneous intake, does not also need to measure the dynamic response of controlled structures and the controlling method of dynamic load information.
Passive Control is simple in structure because of it, and cost is low, and effectiveness in vibration suppression is good, is easy to safeguard and need not the support of outside resources and need not measure the dynamic response of structure and be subjected to extensive concern, and is with fastest developing speed at present, most widely used; Though the ACTIVE CONTROL effect is best, owing to need the outside that the bigger energy is provided, and the control algorithm of control gear is the most complicated, thus less in the practical application; Half ACTIVE CONTROL is between ACTIVE CONTROL and Passive Control, and cost is more reasonable, and controls effectively, has a extensive future; Mix and control the advantage that combines preceding several controlling methods, have and control effect preferably.
Measure is vibrational energy to be introduced the special mechanism that is provided with and element consumed and absorb to passive energy dissipation as a kind of structure Passive Control, promptly some member designs in machinery or the structure is become the power consumption parts or disposes damper at some position, energy during with consumption structural vibration reaches the purpose of subduing vibration.The selection of passive energy dissipation mode is determining the effectiveness in vibration suppression of structure.Energy-dissipating device mainly is divided into four classes according to the Energy Dissipation Mechanism difference: viscous damper, viscoelastic damper, metal damper and frcition damper.Frcition damper is formed the mechanism that can produce slip and frictional force by the metal friction sheet under certain pretightening force, by the slide relative of structural vibrations drive frcition damper, reach the purpose of vibration damping.Frcition damper since simple in structure, power consumption obviously, load frequency and cycle-index do not have much affect to its performance, therefore be most widely used.Viscous damper generally is made up of cylinder body, piston and viscous liquid; have on the piston aperture or and casing wall between leave the gap; but piston is to-and-fro motion in cylinder body; resisting medium is by the space on the piston; the partial vibration energy of structure viscosity property and the hole effect that contracts by damping material dissipated, reach the purpose that reduces structural vibration reaction, protection structure.Viscous damper has the advantage of little rigidity, highly energy-consuming, stroke and ouput force big and good reliability and durability, and this is needed at building, machinery and ocean platform, and viscous damper has good application prospects in engineering.
Pall frcition damper, Sunito-me frcition damper, fricting shearing hinge damper are present general dampers.These dampers have good enclosed pasture characteristic, power consumption obviously and draw materials easily, but shortcoming is no matter whether damper works, and has positive pressure all the time, long-term static friction can produce cold bonding and tie, and has reduced the proper functioning ability.
