Abstract
The invention discloses an eccentric type steel mesh pad damper which comprises an inner shaft rod, a left end cover, a steel mesh pad, a damper middle tube and a right end cover, wherein the left end cover, the steel mesh pad, the damper middle tube and the right end cover are arranged in the inner shaft rod and are in an eccentric structure, and the steel mesh pad is arranged among the left end cover, the damper middle tube and the right end cover. Compared with traditional rubber dampers, the invention has the advantages of resisting to oil, corrosion, temperature difference, humidity and ageing, being easy to maintain and the like, absorbs the vibrational energy in a two-way mode, has adjustable preload, can meet the installing requirements of asymmetrical narrow space, is easy to install, can be properly regulated according to actual installing space, and can be applied to the vibration reduction of a mechanical structure under very bad conditions, and in particular to the vibration reduction of suspension mounting of aircraft engines.
Description
Technical field
The present invention relates to a kind of design of the vibration damper based on eccentric steel net pad damping member.This invention can be used to have the occasion of eccentric vibration damping requirement, is specially adapted to aeroengine and hangs the installation vibration damping.
Background technique
Along with the raising of the speed and motor-driven of aircraft, boats and ships, vehicle, vibration and noise has become to be influenced riding comfort and causes the outstanding problem that instrument and equipment damages.What is more important, strong vibration can make housing construction owing to being in for a long time under the alternating stress effect fatigue fracture take place, so people are to the demands for higher performance of vibration damper.The steel net pad vibration damper is a kind of nonlinear vibration reduction element with dry friction damping characteristics, and advantage is to bear large deformation, has impact resistance.Since big damping can be in broad frequency band vibration damping, compare with rubber shock absorber, the steel net pad vibration damper has anti-oily, anticorrosive, advantages such as temperature resistance is poor, moisture-resistant degree, ageing-resistant, easy care.But existing steel net pad is axially symmetric structure, and the steel net pad vibration damper also is axisymmetric, and it is bigger to take volume.For aeroengine was installed, its connecting rod was very little by the space of motor one side, but bigger by the space of fuselage outer side.The present invention is directed to this actual conditions, design eccentric steel net pad vibration damping connecting rod satisfies special design requirement.
Summary of the invention
The present invention is directed to problem that existing steel net pad vibration damper can not be used for eccentric vibration damping occasion of installing and proposed a kind of scheme of design of vibration damper of eccentric steel net pad.The vibration damping connecting rod that the present invention can be used to have in the asymmetric space arranges, advantage such as also have two-way absorption vibrational energy simultaneously, pretension is adjustable.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of eccentric steel net pad vibration damper, comprise inner shaft lever and be arranged on tube and right end cap in left end cap on the inner shaft lever, steel net pad, the vibration damper, described steel net pad is arranged in left end cap, the vibration damper between tube and the right end cap, it is characterized in that: tube, right end cap and steel net pad are eccentric structure in described left end cap, the vibration damper.
On described inner shaft lever, also be provided with the eccentric trim ring, be provided with described steel net pad in the both sides of eccentric trim ring trim ring.
Also be provided with an end trim ring on described inner shaft lever, this end trim ring is connected with described right end cap.
Trim ring in the middle of also being provided with between described eccentric trim ring and end trim ring, this centre trim ring is connected with described middle tube one end.
The main damping vibration attenuation element of the present invention is a steel net pad, and it is to be formed through specific operation braiding, winding, compacting by Stainless Steel Wire.Its damping vibration attenuation performance mainly is to be caused by the friction between steel wire, can consumed energy in when vibration, reach effectiveness in vibration suppression.The steel net pad vibration damper belongs to the nonlinear vibration reduction device with dry friction hysteretic damping characteristic, bigger friction hysteretic damping can be provided in the frequency band of broad, also has soft-sclerosis rigidity, under unexpected big excitation, because the stiffness variation of element, the natural frequency of structure is changed, thereby suppress mesomerism.The present invention has used eccentric cylindrical steel mesh pad, as the 6 general eccentric steel net pads of the part among Fig. 1.
Beneficial effect of the present invention: 1, compare with traditional rubber shock absorber, the present invention has anti-oily, anticorrosive, advantages such as temperature resistance is poor, moisture-resistant degree, ageing-resistant, easy care; 2, two-way absorption vibrational energy, pretension is adjustable; 3, can satisfy the requirement that asymmetric small space is installed; 4, be easy to install, can be according to as installed space appropriate regulation; Can be used for the mechanical structure vibration damping under the mal-condition, be specially adapted to aeroengine and hang the installation vibration damping.
Description of drawings
Fig. 1 is the general assembly drawing of eccentric steel net pad vibration damper.
Fig. 2 is an eccentric vibration damper left end cap schematic representation.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is an eccentric vibration damper inner shaft lever
Embodiment:
Fig. 1 is the general assembly drawing of eccentric steel net pad damping rod.Among the figure: 1 is eccentric vibration damper left end cap, and 2 is eccentric vibration damper inner shaft lever, and 3 is tube in the eccentric vibration damper, 4 is the eccentric trim ring, and 5 is middle trim ring, and 6 is general eccentric steel net pad, 7 is the end trim ring, and 8 is eccentric vibration damper right end cap.
The present invention has two-way absorption vibrational energy, advantage that pretension is adjustable.Be connected usefulness, the length that can suitably regulate installation when wherein eccentric vibration damper left end cap 1 is installation with eccentric vibration damper right end cap 8.Have two eccentric steel net pad damping members among the figure altogether, these two eccentric steel net pads are not to work simultaneously when being subjected to unidirectional load.When eccentric vibration damper inner shaft lever 2 tensions, the eccentric steel net pad pressurized on the left side plays the damping energy dissipation effect; When eccentric vibration damper inner shaft lever 2 pressurizeds, the eccentric steel net pad pressurized on the right plays the damping energy dissipation effect, realizes the effect of two-way absorption vibrational energy like this.
Eccentric steel net pad damping rod general assembly implementation process:
1) in the eccentric vibration damper tube 3 li, put into a general eccentric steel net pad 6, in the middle of them, penetrate eccentric vibration damper inner shaft lever 2;
2) eccentric trim ring 4 is put on tube 3 right sides earlier in the eccentric vibration damper, trim ring 5 in the middle of installing again;
3) in No. 5 part trim rings, put into a general eccentric steel net pad 6, adorn end trim ring 7 then;
4) eccentric vibration damper left end cap 1 is installed in tube 3 left sides in the eccentric vibration damper, and eccentric vibration damper right end cap 8 is packed on the eccentric vibration damper inner shaft lever 2.So far, assembling is finished.
