Abstract
The invention relates to a combined high-damping shock absorber which comprises an upper plate and a lower plate. A plurality of helical springs are connected between the upper plate and the lower plate. The combined high-damping shock absorber is characterized in that a damper is mounted between the upper plate and the lower plate. The damper comprises a cylinder which is fixed with the lower plate and filled with damping oil, and a piston is arranged in the cylinder and is fixed with the upper plate. The helical springs are fixed with the upper plate and the lower plate by bolts respectively. The combined high-damping shock absorber has the advantages that the shock absorber is used for absorbing shock of equipment and capable of realizing active and passive isolations, has low-frequency shock absorption and energy dissipation damping effects, and further has excellent buffer performance, is small and light, simple in structure, convenient to use and low-cost.
Description
Technical field
The present invention relates to a kind of combined high damping vibration attenuation device, especially a kind of vibration damper for equipment active damping and passive vibration damping belongs to the vibration control technology field.
Background technique
In some main equipments and construction engineering vibration isolation field, because the vibration environment complexity, low-frequency disturbance is more, and the distrubance source amplitude is bigger, often needs to make system to possess very low frequency and higher damping.
Additional damping device when the technology of using for equipment protection adopts spring damping often now.This method can make system possess the characteristic of low frequency and high damping simultaneously, but the thing followed increases cost and installation difficulty often.Therefore, convenient in order to install, reduce cost, designing a kind of combined high damping vibration attenuation device is that market presses for.Helical spring has been widely used in the vibration damping of every field at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of combined high damping vibration attenuation device be provided, have good anti-vibration performance and bigger damping constant, safe and reliable, volume is small and exquisite, easy to use.
According to technological scheme provided by the invention, a kind of combined high damping vibration attenuation device comprises upper plate and lower plate, connects some helical springs between upper plate and lower plate; Feature is: between described upper plate and lower plate damper is installed.
Described damper comprises and the lower plate fixed cylinder body that piston is set, and piston and upper plate are fixed, and fill damping oil in cylinder body in cylinder body.
Described helical spring is fixed with upper plate and lower plate respectively by bolt.
The present invention has following advantage: the present invention is applicable to equipment is carried out vibration damping, can carry out active and passive isolation, reaches the effect of low frequency vibration damping and damping energy dissipation.Advantages such as the present invention has superior shock-absorbing capacity, and volume is small and exquisite, and is in light weight, simple in structure, easy to use, with low cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the sectional view of damper of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 3: as described in combined high damping vibration attenuation device comprise upper plate 1, lower plate 2, damper 3, helical spring 4, cylinder body 5, piston 6 and damping oil 7 etc.
As shown in Figure 1, the present invention includes upper plate 1 and lower plate 2, connect some helical springs 4 between upper plate 1 and lower plate 2, helical spring 4 is fixing with upper plate 1 and lower plate 2 respectively by bolt, and the number of helical spring 4, diameter and the number of turns design according to actual bearer; Damper 3 is installed between described upper plate 1 and lower plate 2, and as shown in Figure 3, damper 3 comprises cylinder body 5, and cylinder body 5 passes through bolt with lower plate 2, and piston 6 is set in cylinder body 5, and the upper end of piston 6 and upper plate 1 are filled damping oil 7 by bolt in cylinder body 5.
Vibration damper of the present invention adopts helical spring and damper combination, and in use, equipment is subjected to vibration can make helical spring 4 and damper 3 produce distortion, thereby plays the effect of vibration damping and power consumption.The steel wire diameter, the number of turns, the spiral ring diameter that change helical spring 4 can change rigidity, bearing capacity and the stress of elastic body on all directions of space.The big I that changes damper 3 changes the damping size, to satisfy different requirements, and can the safety and steady operation under the low frequency macro-energy disturbed condition that the assurance system goes up in any direction.
All hardwares are stainless steel, High Strength Structural Steel or high-strength aluminum alloy material and make, and impact resistance is strong, and the structural strength height can adapt to various environmental conditions.
