Description

Technical Field

[0001] This application belongs to the field of aircraft tire testing technology, and specifically relates to a method and apparatus for testing the abrasion resistance of aircraft tire tread rubber under rolling and sliding conditions. Background Technology

[0002] During takeoff, landing, and taxiing, aircraft tires may experience cyclical stress and strain under high speed, high load, and high temperature, resulting in a certain degree of wear. As the part that contacts the ground, the wear resistance of the tire tread directly affects the tire's service life and the aircraft's flight safety.

[0003] The wear behavior of aircraft tires differs during takeoff, landing, and taxiing, with the rolling-slip condition being the longest and accounting for the largest proportion of wear. Currently, laboratory methods for testing tire tread wear include AKRON abrasion (GB / T 1689), DIN abrasion (GB / T 9867), and LAT abrasion (GB / T 40797). These methods evaluate the wear resistance of the tread compound by adjusting parameters such as load, speed, or angle to change the test conditions. However, the adjustment range of these parameters is still significantly different from that of aircraft tires under rolling-slip conditions, and cannot be used to equivalently assess the wear of aircraft tire tread compounds under actual rolling-slip conditions. Furthermore, if the tread to be tested is made into a finished sample tire for actual operating condition testing, not only will the testing cost be high, the process cumbersome, and the overall testing and feedback cycle long, but it will also result in a huge waste of human, material, and financial resources. Summary of the Invention

[0004] This application addresses the technical problems mentioned above, such as the inability of conventional testing methods to effectively assess the wear of aircraft tire tread rubber under actual rolling and sliding conditions; and the fact that fabricating the tread to be tested into finished prototypes for actual operating condition testing is not only costly and cumbersome, but also results in a long overall testing and feedback cycle, leading to a significant waste of human, material, and financial resources.

Furthermore, features described with respect to some examples may be combined into other examples.

[0020] Please see Figure 1 , Figure 1 This document presents an overall flowchart of a method for testing the abrasion resistance of an aircraft tire tread compound under rolling and sliding conditions, as provided in an embodiment of this application.

[0021] like Figure 1 As shown, the abrasion resistance test method for aircraft tire tread rubber under this rolling and sliding condition may include at least the following steps: Step 102: Prepare samples according to at least two tread formulations to obtain tread rubber samples corresponding to each tread formulation.

[0022] In the embodiments of this application, the method for testing the abrasion resistance of aircraft tire tread rubber under rolling and sliding conditions can be applied to, but is not limited to, a testing platform. This testing platform can establish communication connections with a sample preparation device and an abrasion testing device, respectively, to control the sample preparation device to perform sample preparation processing according to different tread formulations, and to control the abrasion testing device to perform different types of mechanical testing on the prepared tread rubber samples to obtain corresponding mechanical parameters. Then, the abrasion resistance parameters and abrasion test curves used to characterize the abrasion resistance of the tread rubber samples can be calculated by combining these mechanical parameters. The whole process is simple and has high prediction accuracy. Compared with actual working condition testing, it can not only quickly predict the abrasion resistance of tread rubber without consuming a lot of manpower and resources, but also be used to compare the abrasion resistance between different tread rubbers, greatly improving the overall cost-effectiveness of the test.

[0023] It is understood that the sample preparation apparatus mentioned above may include, but is not limited to, processing equipment such as internal mixers, open mills, cutting machines, and vulcanizing machines, to control different types of processing equipment to process one or more formulation materials in the tread compound. The abrasion testing apparatus mentioned above may include, but is not limited to, hardness testing machines for testing the hardness of aircraft tire tread rubber, tensile testing machines for testing the tensile stress of aircraft tire tread rubber, tear testing machines for testing the tear strength of aircraft tire tread rubber, rebound testing machines for testing the resilience of aircraft tire tread rubber, and high-speed, high-load abrasion testing machines for testing the abrasion of aircraft tire tread rubber. All types of testing machines mentioned here can use established standard testing methods and corresponding testing equipment, which will not be elaborated further here.

[0024] Specifically, when conducting abrasion resistance tests on different aircraft tire tread compounds, the testing platform can, but is not limited to, configure the dosage of all formulation materials corresponding to each tread compound according to at least two tread compounds provided by the testers, and control the sample preparation device to process all formulation materials to obtain the corresponding tread compound samples. Here, each tread compound can correspond to at least two formulation materials, and in order to better detect the influence of different formulation materials on the abrasion resistance of the tread compound, the aforementioned at least two tread compounds can be understood as at least two tread compounds from the same batch, and any two tread compounds may have one or more different formulation materials, while all other formulation materials remain consistent.

[0025] For example, but not limited to, using at least two tread formulations containing six tread formulations, the specific grades and amounts of the seven formulation materials (natural rubber, zinc oxide, stearic acid, antioxidant 4020, anti-reversion agent, sulfur, and accelerator) in these six tread formulations are consistent. The carbon black grades in these six tread formulations are different. Specifically, the carbon black grade of the first tread formulation may be, but is not limited to, N330+N660; the carbon black grade of the second tread formulation may be, but is not limited to, N220+N660; the carbon black grade of the third tread formulation may be, but is not limited to, N339+N660; the carbon black grade of the fourth tread formulation may be, but is not limited to, N234+N660; the carbon black grade of the fifth tread formulation may be, but is not limited to, N134+N660; and the carbon black grade of the sixth tread formulation may be, but is not limited to, N134+N330. It should be noted that although the carbon black grades in the six tread formulations mentioned above are different, the proportion of carbon black in each tread formulation remains consistent with that of all other formulation materials to ensure consistency between tread rubber samples.

[0026] As an optional embodiment of this application, sample preparation is performed according to at least two tread formulations to obtain tread rubber samples corresponding to each tread formulation, including: Based on the proportion of formulation materials corresponding to at least two tread formulations, determine the amount of each formulation material in each tread formulation; All the ingredients in each tread formulation are divided into a first set of ingredients and a second set of ingredients. All the ingredients in the first set of ingredients are then mixed according to their respective amounts to obtain the first sample. All formulation materials in the second material set are mixed with the first sample according to the corresponding dosage, and the first sample after mixing is subjected to open milling to obtain tread rubber samples corresponding to each tread formulation.

[0027] Specifically, during the sample preparation process for each tread formulation, the specific dosage of each formulation material can be determined based on the proportion of each formulation material in the formulation. For example, but not limited to, if the proportion of the eight formulation materials (natural rubber, zinc oxide, stearic acid, antioxidant 4020, carbon black, rejuvenator, sulfur, and accelerator) in a certain tread formulation is 100:3:2:3:50:1.2:1.8:1, then the dosage of natural rubber, zinc oxide, stearic acid, antioxidant 4020, carbon black, rejuvenator, sulfur, and accelerator can be calculated as 100 grams, 3 grams, 2 grams, 3 grams, 50 grams, 1.2 grams, and 1.8 grams, respectively, based on the principle that 1 part corresponds to 1 gram.

[0028] Next, after determining the dosage of each ingredient in each tread compound, to ensure the efficiency and effectiveness of sample preparation, all ingredients in each tread compound can be divided into a first material set and a second material set based on all ingredients included in each tread compound and the ingredients corresponding to different processing equipment. The ingredients in the first material set can be understood, but are not limited to, the ingredients corresponding to the internal mixer, i.e., the ingredients in the first material set can be processed by the internal mixer. The ingredients in the second material set can be understood, but are not limited to, the ingredients corresponding to the open mill, i.e., the ingredients in the second material set and the materials processed by the internal mixer can be processed by the open mill. Of course, in this embodiment, the processing equipment used to prepare tread rubber samples may include, in addition to the internal mixer and open mill mentioned above, vulcanizing machines and cutting machines, etc., and is not limited to these.

[0029] Next, after dividing all the formulation materials in each tread compound into a first material set and a second material set, the formulation materials in the first material set can be fed into a mixer according to the corresponding dosage for mixing to obtain the first sample. Here, taking a certain tread compound containing eight formulation materials, namely natural rubber, zinc oxide, stearic acid, antioxidant 4020, carbon black, rejuvenating agent, sulfur, and accelerator, as an example, the formulation materials in the first material set can specifically include natural rubber, zinc oxide, stearic acid, antioxidant 4020, carbon black, and rejuvenating agent, while the formulation materials in the second material set can specifically include sulfur and accelerator. In the process of mixing the formulation materials in the first material set, natural rubber can be fed into the mixer first. After the torque of the mixer decreases, the other formulation materials in the first material set can be fed into the mixer for processing until they are mixed evenly. After the torque of the mixer decreases, the rubber mass is taken out from the mixer, which is the first sample.

[0030] Next, after obtaining the first sample after internal mixing, it is possible, but not limited to, first placing the first sample on the rollers of a two-roll mill for rolling to obtain a sheet of a specified thickness and then cooling it. This sheet can then be mixed with the formulation materials from the second material set, and the mixed sample can be rolled through the rollers of the two-roll mill to obtain a tread rubber sample. For example, taking the formulation materials in the second material set mentioned above as specifically including sulfur and accelerators, the rubber clumps taken from the internal mixer can be placed on the rollers of the two-roll mill, pressed into a 1mm thick sheet for cooling, and then clumped together. Then, they can be placed back on the rollers of the two-roll mill, sulfur and accelerators added, and after forming three triangular clumps, the mixed rubber sheet can be removed.

[0031] As another optional embodiment of this application, before performing mechanical testing on each tread rubber sample to obtain at least two mechanical parameters corresponding to each tread rubber sample, the method further includes: According to the preset test requirements, the tread rubber samples corresponding to each tread compound are cut and processed. Each tread rubber sample, after being cut, is subjected to vulcanization. Each tread rubber sample underwent mechanical testing to obtain at least two mechanical parameters corresponding to each tread rubber sample, including: Each vulcanized tread rubber sample was subjected to mechanical testing to obtain at least two mechanical parameters corresponding to each tread rubber sample.

[0032] To effectively improve the processing efficiency of each tread rubber sample during mechanical testing, each tread rubber sample can also be processed through vulcanization and cutting to obtain a tread rubber sample shape and quality more suitable for mechanical testing.

[0033] Specifically, after obtaining each tread rubber sample, each tread rubber sample can be cut according to the sample shape requirements corresponding to the various types of testing machines mentioned above, but is not limited to. For example, but is not limited to, the target shape of each tread rubber sample can be determined by a preset mold corresponding to various types of testing machines, and each tread rubber sample can be cut according to the target shape by a cutting machine.

[0034] Next, after cutting each tread rubber sample, the processed tread rubber sample can be placed in a stainless steel mold groove, the mold cover is closed, and the mold is placed on a high-temperature flat vulcanizing machine. The mold is vulcanized by extrusion and high temperature treatment until a tread rubber sample that meets the mechanical test requirements is obtained after 45 minutes.

[0035] Step 104: Perform mechanical testing on each tread rubber sample to obtain at least two mechanical parameters corresponding to each tread rubber sample.

[0036] Specifically, after obtaining each tread rubber sample, each tread rubber sample can be tested and processed according to the set standard test method, but is not limited to using the various types of testing machines mentioned above, to obtain at least two mechanical parameters. These at least two mechanical parameters can be any two of Shore hardness, tensile stress, right-angle tear strength without cut, and resilience.

[0037] As another optional embodiment of this application, each tread rubber sample is subjected to mechanical testing to obtain at least two mechanical parameters corresponding to each tread rubber sample, including: Each tread rubber sample was subjected to a hardness test to obtain the Shore hardness corresponding to each tread rubber sample; Tensile tests were performed on each tread rubber sample to obtain the constant tensile stress corresponding to each tread rubber sample; Each tread rubber sample was subjected to a tear test to obtain the right-angle uncut tear strength corresponding to each tread rubber sample; Each tread rubber sample is cut according to a preset shape, and a rebound test is performed on each tread rubber sample after the cutting process to obtain the rebound rate corresponding to each tread rubber sample. Shore hardness, tensile stress, right-angle uncut tear strength, and resilience corresponding to each tread rubber sample are used as at least two mechanical parameters.

[0038] Specifically, during the mechanical testing of each tread rubber sample, the hardness testing machine can be controlled to perform hardness testing on each tread rubber sample according to a set standard hardness testing method to obtain the corresponding Shore hardness. Next, the tensile testing machine can be controlled to perform tensile testing on each tread rubber sample according to a set standard tensile stress testing method to obtain the corresponding 300% constant elongation stress. Then, the tear testing machine can be controlled to perform tear testing on each tread rubber sample according to a set standard tear strength testing method to obtain the corresponding right-angle tear strength without cut. Next, since the sample processing shape corresponding to the rebound testing machine is different from the aforementioned testing machines, the tread rubber sample can be cut using a cutting blade according to a preset shape corresponding to the rebound testing machine to obtain a tread rubber sample shape that meets the rebound test requirements. Then, the rebound testing machine can be controlled to perform rebound testing on the cut tread rubber sample according to a set standard rebound test method to obtain the corresponding rebound rate.

[0039] It is understood that after obtaining the Shore hardness, tensile stress, right-angle uncut tear strength, and resilience corresponding to each tread rubber sample through the aforementioned various types of testing machines, these parameters can be used together as at least two mechanical parameters to subsequently calculate the abrasion resistance reference value corresponding to the tread rubber sample. Of course, in the embodiments of this application, the at least two mechanical parameters can also be any two of the aforementioned Shore hardness, tensile stress, right-angle uncut tear strength, and resilience, and are not limited to these.

[0040] Step 106: Perform wear test on the sample tires configured for each tread rubber sample to obtain the wear weight corresponding to each tread rubber sample, and generate a wear test curve based on at least two mechanical parameters and wear weight corresponding to all tread rubber samples.

[0041] Specifically, after testing at least two mechanical parameters corresponding to each tread rubber sample, the abrasion resistance parameter of each tread rubber sample can be calculated based on, but is not limited to, these at least two mechanical parameters and a preset coefficient. Here, the preset coefficient can be understood as any constant within the range of 1.8-4.2. For example, taking the at least two mechanical parameters as Shore hardness, tensile stress, right-angle tear strength without notch, and resilience as mentioned above, the abrasion resistance parameter of each tread rubber sample can be calculated using the following formula: In the above formula, F can correspond to the wear resistance parameter, and H can correspond to the Shore hardness. This corresponds to a constant tensile stress of 300%. This can correspond to a preset coefficient. R can be represented as the right-angle tear strength without a cut, and R can be represented as the springback rate.

[0042] Furthermore, after calculating the abrasion resistance parameters of each tread rubber sample, the corresponding abrasion volume can be calculated based on, but is not limited to, the abrasion weight of each tread rubber sample. A abrasion test curve can then be constructed by combining the abrasion volume of each tread rubber sample with the corresponding abrasion resistance parameters. It is understood that the abrasion weight of each tread rubber sample can be specifically obtained by performing abrasion tests on each tread rubber sample using a high-speed, high-load abrasion testing machine in this field, and by measuring the weight difference of each tread rubber sample before and after the abrasion test treatment (in grams).

[0043] Here, the specific method for calculating the corresponding wear volume based on the wear weight of each tread rubber sample can be to measure the density of each tread rubber sample using an analytical balance in this field to obtain the density of each tread rubber sample (in grams per cubic centimeter), and then calculate the corresponding wear volume by calculating the ratio between the wear weight and density of each tread rubber sample. In the embodiments of this application, the sample densities corresponding to different tread formulations are different, and the density of each tread rubber sample can be within a preset density range (for example, around 1.11). If the density of any tread rubber sample is not within the preset density range, the tread rubber sample needs to be re-prepared, or the tread formulation corresponding to the tread rubber sample needs to be manually tested, and this is not limited to these methods.

[0044] It is also understandable that, by combining the wear volume of each tread rubber sample with the corresponding wear resistance parameters, the constructed wear test curve can specifically include all tread rubber samples from the same batch, and each tread rubber sample is represented in the wear test curve in the form of wear coordinates. In the wear coordinates of each tread rubber sample, the horizontal axis can be, but is not limited to, the wear resistance parameter, and the vertical axis can be, but is not limited to, the wear volume. The corresponding wear test curve is obtained by connecting the wear coordinates of any two adjacent tread rubber samples with a straight line.

[0045] Step 108: Fit the wear test curve and determine the target tread formula from the fitted wear test curve.

[0046] Specifically, after constructing the wear test curve, to ensure the smoothness of the curve, a smoothing fitting process can be performed on the wear test curve, but is not limited to, to obtain a linear curve with a consistent slope. The coordinates of the tread compound sample that meets the user's requirements can be determined based on the wear resistance law corresponding to this linear curve. Furthermore, the corresponding target tread compound can be obtained based on the coordinates of this tread compound sample that meets the user's requirements. Here, the wear resistance law corresponding to the linear curve can be, but is not limited to, a gradual decrease in wear volume as the wear resistance parameter increases, i.e., better wear resistance. For example, the tread compound corresponding to the tread compound sample with the smallest wear volume can be used as the target tread compound.

[0047] As another optional embodiment of this application, before determining the target tread compound from the fitted wear test curve, the method further includes: The wear coordinates corresponding to each tread rubber sample are determined in the wear test curve, and the distance between each wear coordinate and the fitted wear test curve is calculated. The target tread compound was determined from the fitted wear test curves, including: When any distance is detected to be below the preset distance threshold, the target tread compound is determined from the fitted wear test curve.

[0048] Specifically, after smoothing and fitting the wear test curve to obtain a linear curve with a consistent slope, in order to ensure the correlation between the wear resistance parameter and the wear volume in the wear test curve, the Euclidean distance between each wear coordinate and the linear curve can be calculated separately. When it is detected that no distance exceeds the preset distance threshold, it indicates that there is a strong correlation between the wear resistance parameter and the wear volume of all tread rubber samples corresponding to the same batch. Then, the tread rubber sample coordinates that meet the user's needs and the corresponding target tread formula can be determined according to the wear resistance law corresponding to the linear curve.

[0049] It is understood that when any distance exceeds the preset distance threshold, it indicates that there is a weak correlation between the wear resistance parameter and wear volume of any tread rubber sample among all the tread rubber samples in the same batch. In this case, the preset coefficient mentioned above can be adjusted, or the formulation material of the corresponding tread rubber sample can be replaced, to repeat one or more of the above-mentioned embodiments until no distance exceeds the preset distance threshold, and is not limited to this.

[0050] As another optional embodiment of this application, please refer to the following schematic table of formulation material types for all tread formulations in the same batch: This batch contains six tread formulations. Each formulation improves wear resistance by changing the grade of carbon black, while keeping other formulation materials consistent. For example, but not limited to, the carbon black grades for the first tread formulation are N330+N660, the second tread formulation is N220+N660, the third tread formulation is N339+N660, the fourth tread formulation is N234+N660, the fifth tread formulation is N134+N660, and the sixth tread formulation is N134+N330.

The linear curve obtained by fitting shows that there is a strong correlation between the wear resistance parameter and the wear volume corresponding to each tread compound in the wear test curve.

[0057] As another optional embodiment of this application, in order to determine whether different values ​​of the preset coefficient affect the correlation between the wear resistance parameters and wear volume corresponding to each tread compound in the wear test curve, please refer to... Figure 5 The diagram shows the effect of another wear test curve provided by an embodiment of this application. For example... Figure 5 As shown, the wear test curves correspond to six preset coefficient values, with all tread compounds remaining consistent across all curves. Specifically, the first row (left) corresponds to a preset coefficient of 0.3, the first row (right) to 0.7, the second row (left) to 1.8, the second row (right) to 3, the third row (left) to 4.8, and the third row (right) to 10. By comparing the various wear test curves and their corresponding fitted curves, it is clear that when the preset coefficient is 1.8 or 3, there is a strong correlation between the wear resistance parameters and wear volume corresponding to each tread compound in the wear test curve; when the preset coefficient is 0.3, 0.7, 4.8, or 10, there is a weaker correlation between the wear resistance parameters and wear volume corresponding to each tread compound in the wear test curve.
