Description
Technical field
The invention belongs to damping alloy technical field, more particularly, to a kind of raising damping alloy corrosion resistance
Method.
Background technique
Vibration and noise control is Aeronautics and Astronautics, the energy, traffic, military project, mechanized equipment, building, that people occupies mitigation etc. is numerous
The critical issue that field must be taken into consideration and solve.Excessive vibration can cause structure to destroy, reliability reduction, energy waste, make an uproar
Sound pollution etc., or even cause catastrophic destruction.In consideration of it, vibration and noise control technology is each major industrial country, the world always
The key areas that family is competitively studied, and preferentially applied in some national defence and civilian leading-edge field.Traditional noise reduction mode has
System damping and structural damping mainly include sound absorption processing, sound insulation processing, use silencer, the isolation and damping vibration attenuation of vibration.
The basic principle is that thermal energy is converted by the interaction sound energy consumption of noise sound wave and acoustical material or acoustic construction, from
And achieve the purpose that reduce noise.But the noise reduction of this mode also has the shortcomings that obvious, i.e., whole system is huger stupid
Weight, it is poor to the control ability of low-frequency noise, and will affect the overall performance of aircraft, increase the fuel consumption of aircraft, it will usually
Change the structure of dynamical system, the resonance of various mode occurs to avoid structure and vibration environment；Or the power according to vibration
Principle is learned, some insulators are designed or add, reduces radiation propagation of the vibrational energy from source to peripheral parts.Damping structure
Introducing can directly increase system impost, energy requirements and matched complexity, be increasingly difficult to meet dynamic structure
In the application it is increasingly universal it is accurate, efficient, dexterous, energy saving, reliable, adaptive etc. require, do not meet the development of modern aircraft
Direction.In order to cope with the above challenge, a kind of new noise reduction mode is needed, this mode should have following advantage: to low-frequency noise
Noise reduction is good；System weight is light, and is not usually required to the existing structure design of modification aircraft；By in conjunction with traditional noise reduction measure,
Noise can preferably be inhibited in low frequency, high band.The material damping theory of vibration noise developed in recent years meets above
Required, therefore be also most promising at present to realize the solution that integrally controls of Cockpit Noise.
The material that damping value (Q-1 or tan δ) is more than 0.01 is usually defined as high damping material by material damping.Material
Damping capacity belongs to tired (Break-down) performance that collapses of physics, various dependent on material internal to the extinction efficiency of vibrational energy
Defect sturcture on scale is to the relaxation response mode (i.e. in-fighting) of vibrational energy, thus most of conventional damper material (such as viscoelastics
Property damping material) high damping characteristic be all to be obtained to sacrifice strength character as cost, the decline of strength character is necessarily led
The reduction of corrosion resistance is caused, this significantly limits the application of high damping material.Although directlying adopt with high damping characteristic
Material achieve the purpose that vibration and noise reducing, but the limitation of mechanical property and corrosion resistance generally requires and structural material group
Close application.The present invention is the improvement carried out on the basis of above-mentioned technical problem.
