The principle of cleaning stains on an air conditioner in a layered mode through ultrasonic coupling resonance is as follows:
when the horizontal shear wave propagates in the structure, the particle displacement direction is parallel to the surface and perpendicular to the wave propagation direction, so that the method has unique advantages in the aspect of interface shear delamination. Because the thickness of the stain attached to the upper surface of the bottom shell of the air outlet of the air conditioner is far smaller than that of the bottom shell at the air outlet, the relationship between the stain and the bottom shell can be represented by the following solid layered model:
specifically, dust and dirt accumulated in the air conditioner are used as a coating layer, a bottom shell at an air outlet of the air conditioner is used as a base body, and lambda, mu, rho and h are respectively a first Lame constant, a second Lame constant, density and thickness.
As shown in fig. 2, an origin three-dimensional rectangular coordinate system is established at two sub-interfaces formed by the bottom shell of the air outlet and the dirt, wherein x is1Direction of propagation of horizontal shear waves, x2Is the thickness direction of the substrate, x3The direction is perpendicular to the paper surface and is the particle displacement polarization direction. An ultrasonic excitation source is applied to the end face at the origin. The axial vibration of the ultrasonic excitation source can be converted into bulk acoustic waves on the end face of the substrate, and the bulk acoustic waves are converted into interface shear waves after being transmitted to the substrate and the coating.
The excitation source is represented by a dirac function: f ═ F0δ(x1)e-iωt，ω＝2πf，

The interfacial shear stress of the layered model can be uniformly expressed as:
Figure BDA0003252284510000079
in the formula P(n)(s) is an integration function with s as an integration factor, related to the excitation source frequency, structural parameters, and material parameters. The linear positive correlation between the amplitude of the excitation source and the interface shear stress can be obtained.
From the strength theory, the necessary conditions for obtaining the interface shear delamination are as follows:
Figure BDA0003252284510000081
|P(n)(s) | > 1. Wherein sigmajmWhen the amplitude of the interface shear stress is larger than the interface shear strength, the interface is subjected to shear delamination. Bringing (4) into (5) to let σjm＝f0That is, when the excitation amplitude is equal to the interface shear strength, the necessary conditions for interface delamination are (6), | P(n)(s) | is referred to as normalized interfacial shear stress magnitude.
According to the coupling resonance mechanism of the interface shear stress, the maximum interface shear stress amplitude is obtained at the coupling resonance frequency, so that the optimal layering effect can be obtained, and when the thickness of a coating is certain and is smaller than the coupling resonance frequency range, the excitation frequency is positively correlated with the normalized interface shear stress; when the excitation frequency is certain, the cladding thickness and the normalized interface shear stress are in positive correlation within the range of being less than the coupling resonance thickness.
The dirty layer attached to the bottom shell of the air outlet can be similar to a thin soil layer with uniform density but non-uniform thickness, and the thickness interval is taken

While mu(1)、ρ(1)、λ(1)、ρ(2)、μ(2)、λ(2)All can be obtained by material inspection, and the material is simulatedAnd normalizing the relation curve of the amplitude of the interface shear stress and the excitation frequency. At | P(n)The layered excitation frequency/coupled resonance frequency f is obtained at 1. At this frequency, the magnitude f of the ultrasonic excitation amplitude is determined or adjusted according to a certain thickness value of the coating to be controlled0Obtaining the thickness of the stain layer corresponding to the air outlet structure material
