Background technique
Develop rapidly along with high-tech industries such as carrier rocket, satellite, guided missile, naval vessels, the function of system is variation day by day, structure also maximizes day by day and is complicated, and the performance of system and required precision are also more and more stricter, and it is complicated more that the dynamics of structure also becomes.Its high-power advancing means, rotating machinery, and violent fluid friction becomes the vibrating source of structural vibration in the working procedure.Excitation has wide band and characteristic at random usually, can cause many resonance peaks resonance phenomena of structure, causes the precision of system's operation, usefulness to descend, and produces much noise, structure fatigue damage, even cause catastrophic consequence.Damping based on damping material strengthens the damping level that damping technology can effectively increase structure, suppresses structural vibrations in wide frequency ranges, absorption of noise.Concrete measure has two kinds: the one, and needs are carried out the position of vibration damping processing and directly make the damping enhancing structural member that constitutes by basic unit, damping layer and restraint layer, can make structural member self promptly have high damping, the function of vibration damping and noise reduction; The 2nd, on the transfer of vibration path, as the antenna on the satellite, sensitive equipment, the naval vessels pipeline is installed the damping level that certain thickness damping layer or constrained damping structure increase structure on the isostructural surface of advancing means shell.And adopt rubber damping material in traditional damping enhancing structure.General Purpose Rubber material corrosion resistance is poor, the operating temperature interval is narrow, and the moisture-proof oil resistance is poor, easily wears out and vacuum volatilization, is not suitable for the vibration damping and the abominable working environment such as high and low temperature and vacuum of long-time running equipment.And the rubber material volatilization easily causes pollution and the erosion to sensitive equipment under vacuum environment.
Summary of the invention
Existing General Purpose Rubber material corrosion resistance is poor, the operating temperature interval is narrow, the moisture-proof oil resistance is poor in order to solve in the present invention, easily aging and vacuum volatilization, and is not suitable for the vibration damping under the working environments such as long-time running equipment and high and low temperature and vacuum; And the rubber material volatilization easily causes the problem to the pollution and the erosion of sensitive equipment under vacuum environment, and it is the composite damping material of metal-rubber that a kind of interlayer now is provided, and the concrete technological scheme that addresses the above problem is as follows:
The present invention comprises basic unit, metal-rubber layer and restraint layer, and the metal-rubber layer is clipped between basic unit and the restraint layer, and metal-rubber layer, basic unit and restraint layer fuse, and makes the composite damping material that interlayer is a metal-rubber.
Basic unit and restraint layer can be metallic material or carbon fibre material.
Metal-rubber is raw material with the wire, after formation technique is shaped, has and the similar viscoelasticity of General Purpose Rubber, passes through friction absorption and dissipation energy between the wire under external load function.Metal rubber material possesses that damping capacity is good, in light weight, corrosion resistance is strong, the working temperature environment scope is wide, moisture-proof oil resistant, the aging and not volatile characteristics of vacuum.Therefore, substitute the application area that the General Purpose Rubber material can greatly be expanded damping technology with metal rubber material.
The present invention substitutes traditional rubber material with metal rubber material, has expanded the Applicable scope of interlayer damping enhancing structure.Excellent specific properties such as metal-rubber interlayer damping enhancing structure has corrosion-resistant, and is aging, and high-low temperature resistant and vacuum are non-volatile.The damping of metal-rubber interlayer strengthens structure can be installed on the existing structure surface, existing structure is carried out vibration damping, and need not change the design of original structure, does not reduce the intensity and the reliability of structure.The damping of metal-rubber interlayer strengthens structure also can make the structure member that independently has damping capacity, and vibration damping structure lightweight and damping property are good.The damping of metal-rubber interlayer strengthens structure and has the application mode variation, is applicable to the damping means of making different structure.
