[0052] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] The method for determining the remaining service life of a rubber pad provided by an embodiment of the present application can be applied to, for example, Figure 1 the application environment shown. Among them, the terminal 102 communicates with the server 104 through a network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed in the cloud or on other network servers. Optionally, in this embodiment, the terminal 102 can initiate a request for determining the remaining service life of the rubber pad to be tested to the server 104, and the server responds to the terminal, processes various data, and determines the remaining service life of the rubber pad to be tested. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0054] In one embodiment, as Figure 2 shown, a method for determining the remaining service life of a rubber pad is provided. Taking the server in Figure 1 as an example, the method includes the following steps:

[0055] S201, obtain the target torque of the rubber pad to be tested at the target temperature.

[0056] Optionally, the rubber pad to be tested can be any rubber pad for which the remaining service life needs to be evaluated or predicted.

[0057] The target torque can be the torque measured by testing the screw on the rubber pad to be tested with a torque tester; the magnitude of the target torque is related to the performance state of the rubber pad to be tested at that time. The better the performance state of the rubber pad to be tested, the larger the value of the target torque measured; the worse the performance state of the rubber pad to be tested, the smaller the value of the target torque measured. Among them, the torque tester test can include, but is not limited to, tools such as torque wrenches, screwdrivers, and pulse tools.

[0058] The target temperature is the temperature of the rubber pad to be measured itself at the moment to be measured; generally, the temperature of the rubber pad to be measured is consistent with the ambient temperature.

[0059] Specifically, when the user has a need to determine the remaining service life of the rubber pad to be measured, a remaining service life determination request including the identification information, target temperature, and target torque of the rubber pad to be measured can be sent to the server; then the server can obtain the target temperature and target torque of the rubber pad to be measured from the remaining service life determination request.

[0060] S202. Determine the target torque ratio according to the initial torque and the target torque of the rubber pad to be measured.

[0061] In this embodiment, the initial torque is the torque measured by a torque tester before the rubber pad to be measured is used.

[0062] Specifically, divide the target torque by the initial torque to obtain a ratio, and this ratio is the target torque ratio.

[0063] S203. Based on the correlation between the temperature of the rubber pad to be measured and the performance change rate, determine the target performance change rate according to the target temperature.

[0064] Among them, the performance change rate is a physical parameter used to characterize the relationship between the performance of the rubber pad and the temperature. The performance change rate is related to the material and temperature of the rubber pad; for rubber pads of the same model, the performance change rate is only related to the temperature.

[0065] The correlation between the temperature of the rubber pad to be measured and the performance change rate can be represented by a functional relationship, where the temperature is the independent variable and the performance change rate is the dependent variable. When the temperature changes, the performance change rate also changes with the temperature.

[0066] Furthermore, the target temperature can be substituted into this functional relationship to obtain the target performance change rate.

[0067] S204. Determine the remaining service life of the rubber pad to be measured according to the target performance change rate and the target torque ratio.

[0068] An optional method is to establish a remaining service life determination model based on the sample performance change rate, the sample target torque ratio, and the sample remaining service life. Then, input the target performance change rate and the target torque ratio into the remaining service life determination model, and the corresponding remaining service life is output by the remaining service life determination model.

[0069] The method for determining the remaining service life of the above rubber pad can determine the target performance change rate of the rubber pad to be tested at the target temperature by measuring the target temperature of the rubber pad to be tested and according to the correlation between the temperature of the rubber pad to be tested and the performance change rate. Then, measure the target torque of the rubber pad to be tested to determine the target torque ratio of the rubber pad to be tested. Furthermore, by analyzing the target performance change rate and the target torque ratio of the rubber pad to be tested, the remaining service life of the rubber pad to be tested can be accurately determined. Compared with the traditional method for determining the remaining service life of a rubber pad, the above solution does not require disassembling the rubber pad, avoiding the influence of disassembly on the performance of the rubber pad, and at the same time reducing the labor cost, providing an optional way for reasonably and accurately determining the remaining service life of the rubber pad to be tested.

[0070] Optionally, on the basis of the above embodiment, this embodiment further elaborates on S204 in detail. As Figure 3 shown, the specific implementation process includes the following steps:

[0071] S301, Determine the adjusted torque ratio according to the target torque ratio and the life adjustment parameter of the rubber pad to be tested.

[0072] Among them, the life adjustment parameter is a constant value used to adjust the torque ratio and is related to the material of the rubber pad; optionally, for rubber pads of the same model, the life adjustment parameter is fixed.

[0073] Specifically, take the logarithm of the target torque ratio of the rubber pad to be tested to obtain a logarithmic value; subtract this logarithmic value from the life adjustment parameter, and the obtained difference is the adjusted torque ratio.

[0074] S302, Determine the remaining service life of the rubber pad to be tested according to the adjusted torque ratio and the target performance change rate.

[0075] An optional method is to analyze the data of the adjusted torque ratio, sample performance change rate, and sample remaining service life of a large number of samples to determine a remaining service life determination logic. Furthermore, based on the determined logic, according to the adjusted torque ratio and the target performance change rate of the rubber pad to be tested, the remaining service life of the rubber pad to be tested can be determined.

[0076] Another optional method is to use the ratio between the adjusted torque ratio and the target performance change rate as the remaining service life of the rubber pad to be tested.

[0077] Specifically, divide the adjusted torque ratio by the target performance change rate to obtain a ratio, and the ratio is the remaining service life of the rubber pad to be tested.

[0078] In the above embodiments, by introducing a life adjustment parameter, the target torque ratio is adjusted, and then based on the adjusted target torque ratio, i.e., the adjusted torque ratio, the remaining service life of the rubber pad to be tested is determined, making the determination of the remaining service life more scientific and reasonable.

[0079] Optionally, on the basis of the above embodiments, this embodiment provides an optional example for determining the correlation between temperature and the rate of performance change, such as Figure 4 shown. The specific steps include:

[0080] S401. According to the initial torque and the test torques of the standard rubber pad at different usage days at each test temperature, determine the test performance change rate of the standard rubber pad at each test temperature.

[0081] Among them, the standard rubber pad has the same model as the rubber pad to be tested.

[0082] An optional method is that for each test temperature, according to the initial torque and the test torques of the standard rubber pad at different usage days at this test temperature, determine the test torque ratios of the standard rubber pad at different usage days at this test temperature; according to the general torque ratio model and the test torque ratios of the standard rubber pad at different usage days at this test temperature, determine the test performance change rate of the standard rubber pad at this test temperature.

[0083] In this embodiment, the general torque ratio model can be expressed as y = B·exp{-Kτ}. Where τ is the number-of-days variable, K is the performance change rate, B is a constant, and y is the torque ratio variable.

[0084] Specifically, for each test temperature, the test torques of the standard rubber pad at each usage day at this test temperature can be divided by the initial torque respectively, and the test torque ratios of the standard rubber pad at each usage day at this test temperature can be obtained.

[0085] After that, take the logarithm of the general torque model to obtain a linear function of Y = a + bX, where Y = lny, a = lnB, b = -K, X = τ, and a is the life adjustment parameter, which is related to the constant B.

[0086] Substitute each usage day and the corresponding test torque ratio at this test temperature into the above linear function, and a system of equations can be obtained; use the least squares method to solve this system of equations to obtain the values of a and b in the linear function. Then, based on the value of b, the test performance change rate of the standard rubber pad at this test temperature can be obtained.

[0087] S402. According to the test performance change rates of the standard rubber pad at each test temperature, determine the correlation between temperature and the rate of performance change.

[0088] An optional method is to input the change rate of the test performance of a large number of standard rubber pads at different temperatures and the corresponding test temperatures into the SCILAB software. The SCILAB software performs data analysis to determine the correlation between the change rate of the performance of the standard rubber pad and the temperature. This correlation can be a linear function or a quadratic function.

[0089] Another optional method is to determine the correlation between temperature and the change rate of performance based on the Arrhenius equation and the change rate of the test performance of the standard rubber pad at each test temperature.

[0090] In this embodiment, the Arrhenius equation is:

[0091]

[0092] Where K is the change rate of performance, A is a constant, E is the apparent activation energy, R is the gas constant, which is a fixed value, and T is the temperature.

[0093] Specifically, take the logarithm of the Arrhenius equation to obtain a linear equation with one variable, and substitute multiple sets of data of test temperatures and test performance change rates into the equation to obtain a system of equations; solve the system of equations to obtain a function of the change rate of performance with respect to temperature, that is, the correlation between temperature and the change rate of performance.

[0094] In the above embodiment, by using data such as the torque ratio, number of service days, and temperature of the standard rubber pad, the correlation between temperature and the change rate of performance is determined. When determining the remaining service life of the rubber pad to be tested, as long as the temperature is known, the change rate of performance of the rubber pad to be tested at the current temperature can be determined, which is of great significance for subsequent determination of the remaining service life of the rubber pad to be tested.

[0095] In one embodiment, as Figure 5 shown, a method for determining the remaining service life of a rubber pad is provided. The specific implementation process may include:

[0096] S501. For each test temperature, determine the test torque ratio of the standard rubber pad at different service days at this test temperature according to the initial torque and the test torques of the standard rubber pad at different service days at this test temperature.

[0097] S502. According to the general torque ratio model and the test torque ratios of the standard rubber pad at different service days at this test temperature, determine the test performance change rate of the standard rubber pad at this test temperature.

[0098] S503. According to the test performance change rates of the standard rubber pad at each test temperature, determine the correlation between temperature and the change rate of performance.

[0099] S504, obtain the target torque of the rubber pad to be measured at the target temperature.

[0100] S505, determine the target torque ratio according to the initial torque and the target torque of the rubber pad to be measured.

[0101] S506, based on the correlation between temperature and the rate of performance change, determine the target rate of performance change according to the target temperature.

[0102] S507, determine the remaining service life of the rubber pad to be measured according to the target rate of performance change and the target torque ratio.

[0103] It should be understood that although the steps in the flowcharts involved in the above embodiments are shown in sequence according to the indication of the arrows, these steps do not necessarily have to be executed in the order indicated by the arrows. Unless otherwise clearly stated in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders.
