In order to verify the effectiveness of the technical scheme of the invention, two schemes are established for comparison, wherein the first scheme is a reference model only engraved with a longitudinal groove, as shown in FIG. 3; the second solution is a simulation model arranged according to the tread pattern of the invention, such as the reference model shown in fig. 4, wherein the rectangular blocks have a length of 180mm, a width of 100mm and a height of 30mm, the surfaces of the rectangular blocks form grooves of longitudinal grooves, the grooves have a width of 8mm and a depth of 8 mm; the simulation model shown in fig. 4 is formed with three resonators, each resonator includes two symmetrically arranged narrow grooves, and the cross-sectional shapes of the narrow grooves are rectangular; specifically, the length of a first narrow groove of a first resonator from top to bottom is 74mm, the width of the first narrow groove is 2mm, the depth of the first narrow groove is 5mm, the length of a second narrow groove is 140mm, the width of the second narrow groove is 2mm, the depth of the second narrow groove is 5mm, and the opening distance between the two narrow grooves is 30 mm; the length of a first narrow groove of the second resonator is 97mm, the width of the first narrow groove is 2mm, the depth of the first narrow groove is 5mm, the length of a second narrow groove is 97mm, the width of the second narrow groove is 2mm, the depth of the second narrow groove is 5mm, and the distance between the openings of the two narrow grooves is 30 mm; the first narrow groove length of third resonantor is 81mm, and the width is 2mm, and the degree of depth is 5mm, and second narrow groove length is 110mm, and the width is 2mm, and the degree of depth is 5mm, and two narrow groove opening intervals are 30 mm.
And performing acoustic boundary element simulation on the reference model and the simulation model, and calculating a sound pressure level frequency response function of a middle measuring point in the pipe. And obtaining the tube cavity resonance frequency of the tire and the corresponding sound pressure level amplitude through the sound pressure level frequency response function curve. In the simulation process: the air density was 1.20kg/m3(ii) a The sound velocity in the air is defined as 343.65(1+0.0168i) m/s, and the imaginary part is added to the air to consider that the air in the experimental environment is not ideal gas and has the air damping effect; the sound source type isThe sound pressure amplitude of the monopole sound source is 1N/m.
Fig. 5 shows a comparison of the frequency spectra of two models obtained in simulation, the dotted line in fig. 5 representing the sound pressure level frequency response curve of a reference model without lug and the solid line representing the sound pressure level frequency response curve of a simulated model arranged according to the tread pattern of the invention. As can be seen from FIG. 5, the frequency of the reference model corresponds to a luminal first order frequency of 909Hz and a corresponding sound pressure level amplitude of 142.60 dB; the frequency spectrum of the simulation model arranged according to the tread pattern of the invention has six lower peaks, the frequency of the first peak being 567Hz, the corresponding amplitude peak being 131.33dB, the frequency of the second peak being 696Hz, the corresponding amplitude peak being 129.33dB, the frequency of the third peak being 777Hz, the corresponding amplitude peak being 121.00dB, the frequency of the fourth peak being 980Hz, the corresponding amplitude peak being 119.62dB, the frequency of the fifth peak being 1096Hz, the corresponding amplitude peak being 128.81dB, the frequency of the sixth peak being 1230Hz, and the corresponding amplitude peak being 132.61 dB. See table 1 below.
TABLE 1 comparison of parameters of the present invention and reference model
In the frequency band of 0-2000Hz, the RMS value of the reference model is 161.94dB, the RMS value of the simulation model is 155.98dB, and the lumen noise is reduced by 5.96 dB. The RMS value here refers to the square root of the sum of the squares of all data in the frequency interval, and is used to characterize the amount of energy in the signal.
The tire tread pattern of the invention disperses the concentrated first-order tube cavity resonance peak value into six relatively stable peak values, each peak value is obviously lower than the first-order tube cavity resonance peak value, the difference values between the six simulation model peak values and the reference model peak value are respectively 11.27dB, 13.27dB, 21.6dB, 22.98dB, 13.79dB and 9.99dB, and the peak values are distributed in the frequency band of 550-1250 Hz. Therefore, the tread pattern of the pneumatic tire provided by the invention not only can well reduce the peak value of the primary cavity main resonance peak caused by the longitudinal groove, but also can effectively reduce the peak value caused by the quarter wave tubeTwo peaks. On the other hand, the tread pattern can disperse the concentrated resonance noise of the pipe cavity in a wider frequency band, and the purpose of noise reduction of the tire is well achieved. As for resonator design parameters, since the lumen frequency wavelength is much larger than the linear dimension of the narrow slot, the length of the narrow slot is approximately the narrow slot extension length, expressed by the branched slot resonance frequency formula:
it is known that the longer the narrow groove length, the smaller the resonance frequency, and the larger the narrow groove cross-sectional area, the smaller the resonance frequency; while the narrow slot winding angle a has little effect on the resonant frequency. For a single resonator, the cavity resonance noise can be reduced, mainly because when the resonance frequency of the resonator is near the first-order resonance frequency of the corresponding cavity, due to impedance mismatch caused by discontinuous sectional area near the narrow groove, part of sound waves with specific frequency in the longitudinal groove are reflected, and part of sound waves penetrate into the resonator to generate local resonance dissipation. For the array pattern composed of the resonators, broadband noise reduction can be realized, and the periodic structure of the array pattern enables the noise elimination frequency bands to be partially overlapped, so that the effect of widening the noise elimination frequency band is realized.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
