Abstract
The invention relates to a cylindrical impact damper which comprises a cylindrical cavity and a cover, wherein four small arc steel plates are respectively arranged on an inner wall of the cylindrical cavity; according to the four arc small steel plates, the cylindrical cavity is divided into a middle space and four independent arc spaces with equal volumes around the periphery of the middle space; an impactor is arranged in the middle space; and the lower end of the cylindrical cavity is provided with a fixing seat with a screw hole. The space is fully utilized, the impactor and particle damping agents can be fully collided and rubbed in the cylindrical cavity, the particle damping agents are easily and plastically deformed, the contact frequency between the particle damping agents, the impactor and the cavity is increased, and the opportunity of fully contacting, colliding and rubbing is guaranteed, so that the system has high damping performance.
Description
Technical field
The present invention relates to a kind of impact damper, particularly a kind of cylinder type impact damper.
Background technique
Collisional damping belongs to the Passive Control technology of vibration, and it utilizes the collision of free quality (impactor) and main system in the vibration processes to control the response of main system.Because the impact damper simple structure, with low cost, easy to implement, need not external power, be adapted under the rugged environment using and effectiveness in vibration suppression good, thereby, obtaining recently swift and violent development and in the vibration control in the fields such as lathe, turbomachinery, robot, automobile, aircraft, space shuttle and tall building, be widely used about the research of collisional damping.
The general as required structure of vibration damping of impact damper designs, and the shape of damper inside can be divided into cylinder type, cubic type, irregular type etc. substantially.Impact damper, it produces momentum transfer by the collision between mass block and the main system and controls vibration.Result of study shows, impact damping can more effectively reduce the response amplitude of main system, but there is following shortcoming in it: (1) desirable opposite direction collisions will produce high acceleration peak value and strong velocity discontinuity, thereby produce higher noise, and cause the vessel surface damage; (2) restitution coefficient of collision is higher, and the kinetic energy rejection of impactor is little, thereby must occur in a series of residue collision processes large energy to be turned back to main system with container.
With the impact damper of particle vibration damping agent, refer to by airtight damper cavity and steel ball and a certain amount of impact damper that forms as the subparticle material of vibration damping agent as impactor of inserting wherein.Its damping mechanism is that the particle vibration damping agent that utilizes the strong effect of impact of steel ball in the vibration processes to make to be clipped in therebetween produces plastic deformation, thereby for good and all consumes the vibrational energy of system.With the collisional damping of particle vibration damping agent broken through the conventional butt damping with momentum transfer and friction as the narrow limitation of damping mechanism, in collisional damping, introduced first the irreversible consumption mechanism take the particle plastic deformation as feature.
Existing impact damper and particles-impact damper are not all again planned, are designed the damper inner space, so effectiveness in vibration suppression does not also reach best.
Summary of the invention
The present invention will provide a kind of cylinder type impact damper, mainly solve existing impact damper and particles-impact damper all do not carry out time planning, design to the damper inner space technical problem, it designs, plans by the internal structure to the cylinder type impact damper, so that impactor and particle vibration damping agent wherein can better contact-impacts in damping, thereby the energy of consumption systems better reaches the purpose of vibration damping.
For achieving the above object, technological scheme of the present invention is:
A kind of cylinder type impact damper, comprise cylinder type cavity, lid, be characterized in: this cylinder type cavity inner wall is installed respectively four little steel plates of arc, and these four little steel plates of arc are divided into central space with the cylinder type cavity and are centered around the equal independent arcuate space of four volumes of central space periphery; The central space impactor of packing into.
Cylinder type cavity lower end is provided with the fixed base with screw.
The present invention compares with existing mechanism, has following beneficial effect:
Space in the impact damper cavity of the present invention is fully utilized, impactor and particle vibration damping agent can collide, rub in the cylindrical body cavity more fully, the particle vibration damping agent more easily produces plastic deformation, the contact frequency of particle vibration damping agent and impactor and cavity increases, sufficient contact-impact, rubbing machine meeting have been guaranteed, so that system obtains better damping property.Central space is packed into, and impactor mainly solves existing impact damper and particles-impact damper does not all carry out the inferior technical problem of planning, designing to the damper inner space, it designs, plans by the internal structure to the cylinder type impact damper, so that impactor and particle vibration damping agent wherein can better contact-impacts in damping, thereby the energy of consumption systems better reaches the purpose of vibration damping.
