Problems solved by technology

[0003] The present invention aims to solve the problem of poor corrosion resistance, narrow working temperature range, poor moisture and oil resistance, easy aging and vacuum volatilization of existing ordinary rubber materials, as well as unsuitable for long-term operation of equipment and working conditions such as high, low temperature and vacuum. In addition, the volatilization of rubber materials in a vacuum environment will easily cause pollution and erosion of sensitive equipment. A composite damping material with a metal rubber interlayer is now provided. The specific technical solution to solve the above problems is as follows:

specific Embodiment approach 1

[0009] Specific Embodiment 1: This embodiment will be described with reference to FIG. 1 and FIG. 2 . This embodiment is made up of base layer 101, metal rubber layer 102 and constraint layer 103, metal rubber layer 102 is sandwiched between base layer 101 and constraint layer 103, the lower surface of metal rubber layer 102 and the upper surface of base layer 101 and metal rubber layer 102 The upper surface of the upper surface and the lower surface of the constraining layer 103 are solidified and integrated by epoxy adhesive 104 under a certain temperature and pressure to form a composite damping material with a metal rubber interlayer.

[0010] The base layer 101 is a structural shell that needs to be damped. When the structure vibrates, the metal rubber is deformed, and the metal rubber is rubbed inside to absorb and dissipate energy, so as to achieve the purpose of vibration reduction and noise reduction. Installing the constraint layer 103 outside the metal rubber dampin...

specific Embodiment approach 2

[0011] Specific Embodiment 2: This embodiment is described in conjunction with FIG. 3 . The difference between this embodiment and the first embodiment is that it also includes welding holes 106 and welding points 105, the base layer 101 and the constraining layer 103 are provided with welding holes 106, the lower surface of the metal rubber layer 102 and the upper surface of the base layer 101 The upper surface of the metal rubber layer 102 and the lower surface of the constraining layer 103 are welded together by several welding spots 105 . Others are the same as in the first embodiment. In this embodiment, the welding method is adopted, which is suitable for harsh working environments such as high and low temperature and vacuum.

specific Embodiment approach 3

[0012] Specific Embodiment Three: This embodiment will be described in conjunction with FIG. 5 . The difference between this embodiment and the first embodiment is that the substrate 101 is a hollow plate with an opening on one side, and the metal rubber layer 102 is made into a flat plate, filled in the hollow plate 101, and then the opening is closed to form a sandwich It is a composite damping plate made of metal rubber. When the plate vibrates, it drives the metal rubber damping layer 102 to deform and consume energy. The whole structure can be used as a structural member with vibration damping function. Metal-rubber filler plates are suitable as a support structure with vibration-damping capabilities, and as a clamping structure that can provide elasticity and damping.

Abstract

This invention relates to a composite damp material with a metal rubber interlayer, in which a metal rubber layer is clamped between a base layer and a restriction layer, the lower surface of the metal rubber layer and the top surface of the base layer, the top surface of the rubber layer and the lower surface of the restriction layer are glued together by adhesives to prepare a composite damp material with a metal rubber interlayer, which replaces traditional rubber materials with metal rubber material having the advantages of anti-corrosion, anti-aging, high and low temperature resistant and not volatile in vacuum.

Description

technical field [0001] The invention relates to a composite damping material, in particular to a composite damping material whose interlayer is metal rubber. Background technique [0002] With the rapid development of high-tech industries such as launch vehicles, satellites, missiles, and ships, the functions of the system are becoming more and more diversified, and the structure is becoming larger and more complex. The performance and accuracy requirements of the system are becoming more and more stringent. Features also become more complex. Its high-power propulsion device, rotating machinery, and severe fluid friction in the working process become the excitation source of structural vibration. Excitation usually has wide-band and random characteristics, which can cause multi-formant resonance of the structure, resulting in a decrease in the accuracy and performance of the system operation, a large amount of noise, structural fatigue damage, and even catastrophic conseque...
