Description

Technical Field

[0001] The present invention belongs to the technical field of tire NVH durability evaluation, and in particular relates to a vehicle tire NVH durability attenuation evaluation system and method. Background Art

[0002] As the domestic automobile market matures, consumers are demanding higher levels of vehicle performance and quality. New energy vehicles lack traditional fuel engines, and their electric drive produces less noise overall. Therefore, in-vehicle road noise contributes increasingly to vehicle comfort. The primary excitation source of vehicle road noise is the wheel center vibrations caused by the rough asphalt road surface, which excites the tires and creates a rumbling sound inside the vehicle. If this excitation is too strong or frequent, it can accelerate tire wear. Furthermore, the pumping noise caused by the friction between the asphalt road surface and the tires creates a whining sound inside the vehicle, which can also accelerate tire wear. The friction is particularly intense on rough asphalt roads, shortening tire life. As tires wear, the noise they create increases, further reducing vehicle comfort. Therefore, a solution is needed to help customers accurately identify tire durability, objectively analyze vehicle usage, and ultimately improve vehicle comfort. Currently, OEMs only determine tire NVH (Noise, Vibration, Harshness) durability by measuring tire tread wear. However, there are cases where vehicles are used less frequently and the tire tread is not worn, but the tire rubber hardens, causing the road noise and tread noise inside the vehicle to increase significantly. There is currently no effective evaluation method for tire durability in this situation. Summary of the Invention

[0003] In order to more effectively evaluate tire durability, the present invention proposes a vehicle tire NVH durability attenuation evaluation system and method.

[0004] A vehicle tire NVH durability attenuation evaluation system to achieve one of the objectives of the present invention comprises:

[0005] Modal index acquisition module: used to calculate multiple modal calculation values ​​of transmission force based on the frequency and amplitude of multiple modes of transmission force obtained from the tire transmission force test; the modal calculation values ​​are used to represent the vibration transmission characteristics of the tire in different modes;

[0006] Noise data calculation module: used to obtain the calculated value of the front and rear tire pumping noise based on the front and rear tire pumping noise data; the calculated value of the front and rear tire pumping noise is used to indicate the noise level of the tire, and the noise is related to the durability of the tire;

[0007] A durability value calculation module is configured to calculate the durability value of the tire to be evaluated and the durability value of the comparison tire based on the modal calculation values ​​of the multiple transmission forces and the pumping noise at the front and rear ends of the tire;

[0008] NVH durability attenuation evaluation index calculation module: used to compare the durability value of the tire to be evaluated with the durability value of the comparison tire to obtain the NVH durability attenuation evaluation index of the tire to be evaluated.

[0009] Furthermore, the modal calculation value of each transmission force in the plurality of modal calculation values ​​of the transmission force is equal to a weighted sum of the frequency and the amplitude under the corresponding mode.

[0010] Furthermore, the calculation method of the tire durability value includes: a sum of multiple modal calculation values ​​of the transmission force and the pumping noise values ​​at the front and rear of the tire.

[0011] Furthermore, the frequencies and amplitudes under the multiple modes include a first-order modal frequency and a first-order modal amplitude, and the multiple modal calculation values ​​of the transmitted force include a first-order modal calculation value, and the calculation method thereof includes:

[0012] Mode 1 = W 11 F1+W 12 A1

[0013] Where Mode1 represents the calculated value of the first-order modal of the transmitted force; F1 and A1 represent the first-order modal frequency and the first-order modal amplitude, respectively; W 11 and W 12 They represent the weight of the first-order modal frequency and the weight of the first-order modal amplitude respectively.

[0014] Furthermore, the method for determining the weight of the first-order modal frequency and the weight of the first-order modal amplitude includes: setting the weight of the first-order modal frequency and the weight of the first-order modal amplitude according to the degree of influence on the NVH performance, the greater the influence, the greater the weight, and making the final calculated first-order modal calculation value of the transmission force close to the set value.

[0015] Furthermore, the weight of the first-order modal frequency is greater than the weight of the first-order modal amplitude.

[0016] Furthermore, the frequencies and amplitudes under the multiple modes include second-order modal frequencies and second-order modal amplitudes, and the multiple modal calculation values ​​of the transmitted forces include second-order modal calculation values, and the calculation method includes:

[0017] Mode 2 = W 21 F2+W 22 A2

[0018] Where Mode2 represents the calculated value of the second-order mode of transmission force; F2 and A2 represent the second-order mode frequency and the second-order mode amplitude respectively; W 21 and W 22 They represent the weight of the second-order modal frequency and the weight of the second-order modal amplitude respectively.

[0019] Furthermore, the method for determining the weight of the second-order modal frequency and the weight of the second-order modal amplitude includes: setting the weight of the second-order modal frequency and the weight of the second-order modal amplitude according to the degree of influence on the NVH performance, the greater the influence, the greater the weight, and making the final calculated second-order modal calculation value of the transmission force close to the set value.

[0020] Furthermore, the weight of the second-order modal frequency is smaller than the weight of the second-order modal amplitude.

[0021] Furthermore, the method for calculating the calculated values ​​of the near-field pumping noise in front and behind the tire includes: performing weighted calculation on the noise corresponding to each set frequency in the set frequency range to obtain the calculated values ​​of the near-field pumping noise in front of the tire and the calculated values ​​of the near-field pumping noise in the rear of the tire.

[0022] Furthermore, the set frequency interval is [400Hz, 1350Hz]. Its technical effect is: in the one-third octave analysis, the interval of 400Hz to 3000Hz is used as the range of the mid-frequency band, which usually contains important noise information. In particular, in the study of tire pumping noise, this frequency band may contain key noise characteristics related to tire rolling, airflow disturbances, etc.; by selecting the frequency interval of 400Hz to 1350Hz and analyzing it in a one-third octave manner within this interval, the characteristics of the near-field pumping noise in the front and rear of the tire can be studied more accurately, which helps to identify the main sources, frequency components and intensity distribution of the noise, thereby providing important data support for tire design and noise control; it can more accurately study the noise characteristics and provide a scientific basis for tire design and noise control.

[0023] Furthermore, the method for determining the weights in the weighted calculation of the noise corresponding to each set frequency in the set frequency range includes: allocating weights according to the amplitude corresponding to each frequency, with the higher the amplitude, the greater the weight; and making the final calculated values ​​of the near-field pumping noise in front of the tire and the near-field pumping noise behind the tire both approach the set values.

[0024] Furthermore, the NVH durability attenuation evaluation index for the tire under evaluation is calculated by subtracting the durability value of the control tire from the durability value of the tire under evaluation. The difference is then calculated as the ratio of the difference to the durability value of the control tire. If the ratio is greater than a set value, the tire under evaluation is deemed to have failed the NVH durability attenuation evaluation index, and the customer is advised to replace the tire with a new one to improve vehicle ride comfort.

[0025] A vehicle tire NVH durability attenuation evaluation method for achieving the second objective of the present invention comprises:

[0026] Calculating multiple modal calculation values ​​of the transmission force based on the frequencies and amplitudes of the multiple modes of the transmission force obtained from the tire transmission force test;

[0027] The front and rear tire pumping noise calculation values ​​are obtained based on the front and rear tire pumping noise data;

[0028] Calculating the durability value of the tire to be evaluated and the durability value of the comparison tire based on the multiple modal calculation values ​​of the transmission forces and the front and rear pumping noises of the tire;

[0029] The durability value of the tire to be evaluated is compared with the durability value of the comparison tire to obtain the NVH durability attenuation evaluation index of the tire to be evaluated.

[0030] The beneficial effects of the present invention include:

[0031] 1. Based on vibration data from tire transmission force tests, the frequency and amplitude of the transmission force in multiple modes are calculated, and then multiple modal calculation values ​​of the transmission force are obtained. This accurately quantifies the vibration transmission characteristics of the tire under dynamic conditions and provides an accurate data basis for subsequent NVH performance evaluation.

[0032] 2. Combining the front and rear pumping noise data and the modal calculation value of the transmission force, the durability values ​​of the evaluated and comparison tires are calculated. This fully reflects the overall performance of the tire in terms of noise and vibration, and helps to more comprehensively understand the tire's NVH characteristics;

[0033] 3. By comparing the durability value of the tire to be evaluated with the durability value of the comparison tire, the NVH durability attenuation evaluation index of the tire to be evaluated can be obtained. This can intuitively reflect the attenuation of the tire's NVH performance during use and is of great significance for evaluating the durability and service life of the tire;

[0034] 4. By accurately evaluating and optimizing tires, the present invention can guide users in choosing appropriate tires, thereby enhancing their driving and riding experience. It can be used not only for tire evaluation but also as an important reference for tire design and optimization. By understanding the vibration transfer characteristics and NVH performance of tires in different modes, designers can tailor the tire structure and materials to improve their NVH performance and durability.

The scope of protection of the present invention is not limited to the specific implementation structures described below. Any implementation schemes created by those skilled in the art that incorporate the technical solutions of the present invention claims but differ from the following detailed descriptions are also within the scope of protection of the present invention.

[0041] Example 1

[0042] A method for evaluating vehicle tire NVH durability attenuation

[0043] Calculating multiple modal calculation values ​​of the transmission force based on the frequencies and amplitudes of the multiple modes of the transmission force obtained from the vibration data of the tire transmission force test;

[0044] The front and rear tire pumping noise calculation values ​​are obtained based on the front and rear tire pumping noise data;

[0045] Calculating the durability value of the tire to be evaluated and the durability value of the comparison tire based on the multiple modal calculation values ​​of the transmission forces and the front and rear pumping noises of the tire;

[0046] The durability value of the tire to be evaluated is compared with the durability value of the comparison tire to obtain the NVH durability attenuation evaluation index of the tire to be evaluated.

[0047] In some embodiments, the comparison tire is a comparison tire B that is used on the same vehicle model or tire type as the tire to be evaluated and has a mileage less than a set value. In this embodiment, the mileage of the comparison tire B is ≤20km; the tire A to be evaluated of the vehicle to be evaluated and the comparison tire B of the same vehicle model or type as the vehicle to be evaluated (mileage ≤20km) are subjected to a tire transmission force test and a tire pump noise test.

[0048] In certain embodiments, the tire transmission force test is performed as follows: Figure 2 As shown, a vibration sensor is arranged in the middle of the tire assembly, and the tread is struck by a hammer to read the vibration data of the wheel center vibration sensor, as shown in FIG. Figure 3 As shown, the data is processed into the form of dB(g) / N; the frequencies and amplitudes under the multiple modes include the first-order modal frequency and the first-order modal amplitude.

[0049] Since the first-order modal frequency is more important for the performance of NVH, and in order to make the calculated value of the first-order modal of the transmitted force close to the set value (200 in this embodiment), the weight of the first-order modal frequency W is11 Set to 1.95; the weight of the first-order modal amplitude W 12 Set to 1; perform weighted summation of the first-order modal frequency and the first-order modal amplitude to obtain the first-order modal calculation value of the transmission force, as shown in Table 1; the final first-order modal calculation value of the transmission force of the tire A to be evaluated is Mode1 = W 11 F1+W 12 A1=1.95×119+1×(-20.2)=211.85;Compared with tire B, the first-order modal calculation value of the transmission force Mode1=W 11 F1+W 12 A1=1.95×117+1×(-27.7)=200.45.

[0052] In some embodiments, the frequencies and amplitudes under the multiple modes include the second-order modal frequency and the second-order modal amplitude. Since the second-order modal amplitude is more important for the performance of NVH, and in order to make the second-order modal calculated value of the transmitted force close to the set value (200 in this embodiment), the second-order modal frequency W 21 The weight of the second-order modal amplitude is set to 1.1; the weight of the second-order modal amplitude is W 22 Set to 2; after weighted summation of the second-order modal frequency and the second-order modal amplitude, the second-order modal calculation value of the transmission force Mode2 is obtained, as shown in Table 2; the final second-order modal calculation value of the transmission force of the tire A to be evaluated Mode2 = W 21 F2+W 22 A2=1.1×224+2×(-20.3)=205.8;Compared with tire B, the second-order modal calculation value of the transmission force Mode2=W 21 F2+W 22 A2=1.1×224+2×(-25.6)=195.2.

[0056] In some embodiments, the tire front and rear pumping noise test is as follows Figure 4 As shown in the figure, at a constant speed of 70kmh on a smooth cement road, with a tire height of 200m and a length of 350mm, the mic sensor noise data is read and the data is processed into dBA. The amplitude value at 400Hz-3150Hz is calculated, and the result is as follows Figure 5-1 and 5-2 As shown, Figure 5-1is the near-field pumping noise in front of the tire, Figure 5-2 is the near-field pumping noise behind the tire; it can be seen that the low and high frequencies of 400 Hz and 3150 Hz account for a small proportion and have a small corresponding amplitude, so a weight of 0.1 is set; the low and high frequencies of 800 Hz, 1000 Hz, and 1250 Hz account for a high proportion and have a large corresponding amplitude, so a weight of 0.39 is set, and the calculated value is made close to the set value (200 in this embodiment). Finally, the noise value of each frequency is multiplied by the corresponding weight and summed to obtain the calculated values ​​of the near-field pumping noise in front of the tire and the calculated values ​​of the near-field pumping noise behind the tire.

[0062] Finally, all calculated values ​​are summed, as shown in Table 5, to obtain the durability values ​​of the control tire and the tire under evaluation. The durability value of the tire under evaluation is then compared with the durability value of the control tire. The difference is calculated by subtracting the durability value of the control tire from the durability value of the control tire. The ratio of this difference to the durability value of the control tire provides the NVH durability degradation evaluation index for the tire under evaluation, or the degree of degradation. This degree of degradation can be used to provide targeted guidance to customers on tire replacement and other procedures to improve vehicle comfort. As shown in Table 6, based on the NVH data of the control tire, if the degree of degradation reaches 5% or more, the tire is considered to have experienced NVH durability failure, and the user is advised to replace the tire.
