Description

Tire performance prediction method, tire and vehicle Technical Field

[0001] The present invention relates to the technical field of tires, and in particular to a tire performance prediction method, a tire, and a vehicle. Background Art

[0002] With the rapid development of the domestic electric vehicle market, the problem of tire bulge has become more and more a focus of users' attention. In order to pursue long driving range, electric vehicles have heavy batteries and heavy vehicles; in order to pursue driving experience performance, the motor outputs large and fast torque, and the tires are instantly subjected to large impact energy; in order to pursue beautiful appearance, the rim diameter is large, resulting in a flatter aspect ratio of the tire. Various factors lead to large impact energy on the tire and small buffering energy itself, resulting in a high risk of tire bulge in electric vehicles.

[0003] To reduce the risk of bulging, special materials and advanced processes are currently commonly used, such as anti-bulge technology, thickened sidewall rubber, and shoulder pads, to enhance tire toughness and durability, thereby reducing the chance of bulging. However, the risk of bulging varies with different tire specifications. Traditional methods of initially selecting tire specifications, then testing and optimizing them on different vehicle configurations based on feedback, would significantly increase production costs. Therefore, a method is needed to estimate the bulge risk of tire specifications during the vehicle planning phase, allowing for the selection of appropriate tire specifications to enhance bulge resistance.

[0048] A tire performance prediction method according to an embodiment of the first aspect of the present invention.

[0049] As shown in FIG1 , in Example 1, there are many factors that affect the anti-bulging performance of a tire. In this example, the tire section height coefficient is introduced as an influencing factor. The higher the tire section height coefficient, the stronger the tire sidewall's ability to resist deformation when impacting an obstacle, and the higher the vehicle speed at which the tire bulge fails. The specific implementation process is as follows:

[0050] Step S110, obtaining tire section width;

[0051] Step S120, obtaining the tire aspect ratio;

[0052] Step S130, obtaining a tire section height constant;

[0053] Step S140, comparing the product of the tire section width and the tire aspect ratio with the tire section height constant to obtain a tire section height coefficient;

[0054] Step S150: judging the anti-bulging performance of the tire according to the tire section height coefficient.

[0055] The above specific calculation method can be further expressed by the formula, specifically, taking the tire section height coefficient k as h , h is the tire section height, S N is the tire section width, ar is the tire aspect ratio, h0 is the tire section height constant, and the value range of h0 is between 100 mm and 150 mm. For example, it is 110 mm for sedans and 120 mm for SUVs. The calculation formula for the tire section width h is: Tire section height coefficient k h The calculation formula is: that is

[0056] In this embodiment 1, after the tire specifications are preliminarily selected, the anti-bulging performance of multiple tires that have passed the preliminary selection can be evaluated. By obtaining the tire section width, tire aspect ratio, and tire section height constant, and comparing the product of the tire section width and the tire aspect ratio with the tire section height constant, a ratio is obtained. This ratio is the tire section height coefficient. When the tire section height coefficient is higher, the tire sidewall's ability to resist deformation when it hits an obstacle is stronger, and the speed at which the tire fails due to bulging is higher. In this way, tires with poor anti-bulging performance can be eliminated directly before production and development, and appropriate tire specifications can be selected, which is conducive to avoiding bulging risks in advance, shortening the production and development cycle of the entire vehicle, and improving driving safety.

[0057] 2 , in Example 2, a tire load coefficient is introduced as a factor affecting the tire's anti-bulging performance. The higher the tire load coefficient, the stronger the tire's sidewall's ability to resist deformation when impacting an obstacle, and the higher the vehicle speed at which the tire bulge fails. The specific implementation process is as follows:

[0058] Step S210, obtaining tire section width;

[0059] Step S220, obtaining the tire aspect ratio;

[0060] Step S230, obtaining a tire section height constant;

[0061] Step S240, comparing the product of the tire section width and the tire aspect ratio with the tire section height constant to obtain a tire section height coefficient;

[0062] Step S250, obtaining a tire load index;

[0063] Step S260, obtaining the maximum load of a single wheel side system;

[0064] Step S270 , comparing the tire load index with the maximum load of a single wheel rim system to obtain a tire load coefficient;

[0065] Step S280: Determine the tire's anti-bulging performance based on the tire's section height coefficient and the tire load coefficient.

[0066] The above specific calculation method can be further expressed by the formula. Specifically, the tire load coefficient is k Q , Q T is the tire load capacity, that is, the tire load index corresponding to the tire specification, Q R is the maximum load of a single wheel system, and the tire load factor k Q The calculation formula is:

[0067] In this second embodiment, after the tire specifications are preliminarily selected, the anti-bulging performance of multiple tires that have passed the preliminarily selection is evaluated. After obtaining the tire cross-sectional height coefficient, the tire load index and the maximum load of a single wheel side system are obtained, and the tire load index is compared with the maximum load of a single wheel side system to obtain a ratio. This ratio is the tire load coefficient. By comparing the tire cross-sectional height coefficients and tire load coefficients measured from multiple tires, the tire with the largest value of the tire cross-sectional height coefficient and the tire load coefficient can be selected as the required tire. Tires with larger tire cross-sectional height coefficients are preferred, and then tires with larger tire load coefficients are selected. Finally, the tire with the highest bulging failure speed is selected. In this way, tires with poor anti-bulging performance can be eliminated directly before production and development. Selecting appropriate tire specifications is beneficial to avoid bulging risks in advance, shorten the production and development cycle of the entire vehicle, and improve driving safety.

[0068] 3 , in Example 3, the tire pressure coefficient is introduced as a factor affecting the tire's anti-bulging performance. The higher the tire pressure coefficient, the stronger the tire sidewall's ability to resist deformation when hitting an obstacle, and the higher the vehicle speed at which the tire bulge fails. The specific implementation process is as follows:

[0069] Step S310, obtaining tire section width;

[0070] Step S320, obtaining the tire aspect ratio;

[0071] Step S330, obtaining a tire section height constant;

[0072] Step S340, comparing the product of the tire section width and the tire aspect ratio with the tire section height constant to obtain a tire section height coefficient;

[0073] Step S350, obtaining the tire operating pressure;

[0074] Step S360, obtaining standard inflation pressure;

[0075] Step S370: Compare the tire operating pressure with the standard inflation pressure to obtain the tire pressure coefficient.

[0076] Step S380: Determine the tire's anti-bulging performance based on the tire's section height coefficient and the tire's air pressure coefficient.

[0077] The above specific calculation method can be further expressed by the formula. Specifically, the tire pressure coefficient is k P , P is the tire pressure, P T The standard inflation pressure is 250 kPa for standard tires and 290 kPa for enhanced tires. P The calculation formula is:

[0078] In this third embodiment, similarly, multiple tires that have passed the preliminary selection are evaluated for their anti-bulging performance. By obtaining the tire operating pressure and standard inflation pressure, and then comparing the tire operating pressure with the standard inflation pressure, a ratio is obtained. This ratio is the tire pressure coefficient. By comparing the tire section height coefficients and tire pressure coefficients measured from multiple tires, the tire with the largest values ​​of the tire section height coefficient and the tire pressure coefficient can be selected as the required tire. Tires with larger tire section height coefficients are given priority, and then tires with larger tire pressure coefficients are selected. Finally, the tire with the highest bulge failure speed is selected. In this way, tires with poor anti-bulging performance can be eliminated directly before production and development, and appropriate tire specifications are selected, which is conducive to avoiding bulging risks in advance, shortening the production and development cycle of the entire vehicle, and improving driving safety.

[0079] 4 , in Example 4, the internal volume of the tire is introduced as a factor affecting the anti-bulging performance of the tire. The higher the internal volume of the tire, the stronger the deformation resistance of the tire sidewall when hitting an obstacle, and the higher the vehicle speed at which the tire bulge fails. The specific implementation process is as follows:

[0080] Step S410, obtaining tire section width;

[0081] Step S420, obtaining the tire aspect ratio;

[0082] Step S430, obtaining a tire section height constant;

[0083] Step S440, comparing the product of the tire section width and the tire aspect ratio with the tire section height constant to obtain a tire section height coefficient;

[0084] Step S450, calculating the internal volume of the tire;

[0085] Step S450: Determine the anti-bulging performance of the tire based on the tire section height coefficient and the tire internal volume.

[0086] To calculate the internal volume V of the tire, you can first calculate the rim diameter d r , tire design width S, the specific calculation formula is as follows:

[0087] Rim diameter d r =R×25.4;

[0088] Tire design width S = S N +0.4×(RW×25.4-S N ×R0);

[0089] Tire internal volume V = πd r ×h×S.

[0090] Among them, R is the nominal diameter code of the rim, S N is the tire section width, ar is the tire aspect ratio, RW is the rim width code, R0 is the rim width coefficient, and h is the tire section height. When obtaining the rim diameter value, it is usually in inches and needs to be multiplied by 25.4 to be converted into millimeters. The constant 0.4 is an empirical coefficient adopted after multiple verifications. The value range of the rim width coefficient is between 0.5 and 1. For example, when the tire aspect ratio is greater than or equal to 50, the rim width coefficient is 0.7. When the tire aspect ratio is less than or equal to 45, the rim width coefficient is 0.85.

[0091] When measuring, first calculate the rim diameter and tire design width, and then substitute the calculated values ​​into the tire internal volume calculation formula. The calculation formula for the tire internal volume V is:

[0092] In this fourth embodiment, the data required to be acquired overlaps with the data required to calculate the tire section height coefficient in the first embodiment, such as tire section width, tire section height, and tire aspect ratio. This indicates that the tire section height coefficient is more fundamental and critical, while the tire internal volume requires more comprehensive consideration. In practice, if the tire internal volume is directly used to determine the impact of bulge resistance, multiple preliminarily selected tires are evaluated for bulge resistance. After obtaining the required values, the internal volume of each tire is calculated. By comparing the measured tire section height coefficients and internal volumes of the multiple tires, the tire with the largest value between the two can be selected as the desired tire. Tires with larger section height coefficients are prioritized, followed by tires with larger internal volumes. This allows tires with poor bulge resistance to be eliminated before production and development, allowing for the selection of appropriate tire specifications. This helps prevent bulge risks in advance, shortens the vehicle production and development cycle, and improves driving safety.

[0093] 5 , in Example 5, the tire bulge failure speed is measured, and the specific process is as follows:

[0094] Step S511, obtaining tire section width;

[0095] Step S512, obtaining the tire aspect ratio;

[0096] Step S513, obtaining the tire section height constant;

[0097] Step S514, comparing the product of the tire section width and the tire aspect ratio with the tire section height constant to obtain a tire section height coefficient;

[0098] Step S550, calculating the vehicle speed at which the tire bulge fails;

[0099] Step S560: Determine the tire's anti-bulge performance based on the tire's section height coefficient and the tire bulge failure speed.

[0100] The formula for the vehicle speed due to tire bulge failure is: In this formula, the parameters involved are tire section height coefficient k h It can be obtained from step S511 to step S514. In the second embodiment, the tire load coefficient k can be obtained. Q , Example 3 Tire pressure coefficient k P , the tire internal volume V can be obtained in the fourth embodiment. Therefore, if it is necessary to calculate the tire bulge failure speed in the fifth embodiment, the schemes of the first to fourth embodiments can be combined to obtain the sixth embodiment, as shown in FIG6 . The specific process is as follows:

[0101] Step S510, obtain the tire section height coefficient k h ,in, Through two formulas, we can get:

[0102] Step S520, obtain the tire load coefficient k Q ,

[0103] Step S530, obtain the tire pressure coefficient k P ,

[0104] Step S540: Calculate the tire internal volume V, where d r =R×25.4, S=S N +0.4×(RW×25.4-S N × R0), V=πd r ×h×S, we can get the following through three formulas:

[0105] Step S550: Calculate the tire bulge failure speed and use the calculated tire section height coefficient k h , tire load factor k Q , tire pressure coefficient k P , Substitute the tire internal volume V into the calculation formula: The tire bulge failure speed v is obtained as:

[0106] Step S510 , judging the tire's anti-bulge performance based on the tire section height coefficient and the tire bulge failure speed.

[0107] Among them, R is the nominal diameter code of the rim, h is the tire section height, SN is the tire section width, ar is the tire aspect ratio, h0 is the tire section height constant, Q T is the tire load index, P is the tire pressure, RW is the rim width code, R0 is the rim width coefficient, Q R is the maximum load of a single wheel side system, P T is the standard inflation pressure, k V k is the vehicle constant. V The value range of k is between 0.1 and 0.5. When the vehicle is a passenger car, k V The value of is 0.2. When the vehicle is an SUV, k V The value of is 0.3; the value range of h0 is between 100 mm and 150 mm, for example, 110 mm for sedans and 120 mm for SUVs; the value range of the rim width coefficient R0 is between 0.5 and 1, for example, when the aspect ratio of the tire is greater than or equal to 50, the value of the rim width coefficient R0 is 0.7, and when the aspect ratio of the tire is less than or equal to 45, the value of the rim width coefficient R0 is 0.85.

[0108] Whether in Example 5 or Implementation 6, by comparing the tire bulge failure speeds measured from multiple tires, the tire with the largest tire bulge failure speed can be selected as the required tire. In this way, tires with poor anti-bulge performance can be eliminated before production and development, and appropriate tire specifications can be selected, which is conducive to avoiding bulge risks in advance, shortening the production and development cycle of the entire vehicle, and improving driving safety.

[0109] Taking a three-box electric vehicle project as an example, after preliminary tire specification selection, two options are available: 225 / 45R19 and 225 / 55R17. The anti-bulging performance of these two tire sizes can be estimated to select the appropriate tire size. The specific measurement data is shown in the following table:

[0110] As can be seen from the above table, through theoretical calculation, the estimated vehicle speed at which the 225 / 45R19 tire will fail due to a bulge is 31.92km / h, and the estimated vehicle speed at which the 225 / 55R17 tire will fail due to a bulge is 40.38km / h. The 225 / 55R17 tire will fail due to a bulge at a higher speed, so 225 / 55R17 tires were used for production and development, and finally bulge tests were conducted on actual vehicles with both tire specifications. The actual vehicle speed at which the 225 / 45R19 tire failed due to a bulge was 30km / h, and the actual vehicle speed at which the 225 / 55R17 tire failed due to a bulge was 40km / h. It can be seen that, similarly, the actual vehicle speed at which the 225 / 55R17 tire failed due to a bulge is also higher, and the tire selected based on this anti-bulge tire performance estimation is more suitable.

[0111] According to a tire of an embodiment of the second aspect of the present invention, the above-mentioned tire performance prediction method is used to predict the anti-bulging performance. In the first method, multiple tires after preliminary selection can be compared using any tire performance prediction method in Examples 1 to 6, and the tire with the largest comparison value is the tire to be selected; in the second method, a single tire is directly judged whether it meets the requirements. In this case, any method in Examples 1 to 6 can be selected, and a range value is set for the parameters required for the final judgment in the method. If the value calculated for the tire falls within this range, the tire meets the requirements. For example, using the method of Example 6, the tire bulge failure speed that meets the requirements is set to between 50km / h and 60km / h. When the calculated tire bulge failure speed falls within this range, the tire meets the requirements.

[0112] When selecting tires, tires with anti-bulging performance estimation can effectively detect the anti-bulging performance of the tire. In this way, tires with poor anti-bulging performance can be eliminated before production and development. Selecting appropriate tire specifications is conducive to avoiding bulging risks in advance, shortening the production and development cycle of the entire vehicle, and thus improving the driving safety performance of the entire vehicle.

[0113] According to a third embodiment of the present invention, a vehicle includes a tire according to the second embodiment. Specifically, the vehicle can be a private vehicle, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0114] When selecting tires for vehicle production, in this vehicle, tire production and development are selected after anti-bulging performance estimation, which reduces the vehicle's manufacturing cost, shortens the vehicle production and development cycle, and improves the vehicle's driving safety performance.
