[0002] With the development of the instrumentation industry, bellows have emerged. A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. It converts pressure into displacement or force, serving as the measuring element of a measuring instrument. Bellows have thin walls, high sensitivity, and a measuring range from tens of Pascals to tens of megapascals. They are frequently used in critical parts of important equipment such as aircraft and rockets to measure pressure. Therefore, determining the service life of bellows is of great significance for the operational safety of equipment.

[0003] In traditional techniques, the remaining service life of a bellows can only be determined by disassembling it and conducting a comprehensive inspection. This not only increases the workload of the inspectors, but repeated disassembly and reassembly can also affect the measurement accuracy of the bellows. Summary of the Invention

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] The method for determining the remaining service life of a bellows provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed on a cloud or other network server. Optionally, in this embodiment, terminal 102 can initiate a request to server 104 to determine the remaining service life of the corrugated pipe under test. The server responds to the terminal, processes various data, and determines the remaining service life of the corrugated pipe under test. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0054] In one embodiment, such as Figure 2 As shown, a method for determining the remaining service life of a bellows is provided, which can be applied to... Figure 1 Taking the server in the example, the following steps are included:

[0055] S201, obtain the target height of the bellows under test at the target temperature.

[0056] Optionally, the bellows to be tested can be any bellows whose remaining service life needs to be evaluated or predicted.

[0057] The target height refers to the height of the corrugated pipe being tested using a length tester. The magnitude of the target height is related to the performance condition of the corrugated pipe at that time; the better the performance condition of the corrugated pipe, the smaller the measured target height value; the worse the performance condition of the corrugated pipe, the larger the measured target height value. The length tester can be any tool used for measuring length.

[0058] The target temperature is the temperature of the bellows under test at the time of the test; under normal circumstances, the temperature of the bellows under test is the same as the ambient temperature.

[0059] Specifically, when a user needs to determine the remaining service life of the corrugated pipe to be tested, they can send a remaining service life determination request to the server, which includes the identification information of the corrugated pipe to be tested, the target temperature, and the target height; then the server can obtain the target temperature and target height of the corrugated pipe to be tested from the remaining service life determination request.

[0060] S202, determine the target height ratio based on the initial height and target height of the bellows to be tested.

[0061] In this embodiment, the initial height is the height of the corrugated pipe to be tested, measured by a length tester before use.

[0062] Specifically, the target height is divided by the initial height to obtain a ratio, which is the target height ratio.

[0063] S203, based on the correlation between the temperature and the rate of performance change of the bellows under test, determines the target performance change rate according to the target temperature.

[0064] The performance change rate is a physical parameter used to characterize the relationship between the performance of a bellows and temperature. The performance change rate is related to the material of the bellows and the temperature; for the same type of bellows, the performance change rate is only related to temperature.

[0065] The relationship between the temperature and the rate of performance change of the bellows under test can be represented by a function, where temperature is the independent variable and the rate of performance change is the dependent variable. The rate of performance change changes with temperature.

[0066] Furthermore, by substituting the target temperature into the functional relationship, the rate of change of the target performance can be obtained.

[0067] S204. Determine the remaining service life of the bellows under test based on the target performance change rate and the target height ratio.

[0068] One alternative approach is to establish a remaining useful life determination model based on the sample performance change rate, the sample target height ratio, and the sample remaining useful life. Then, the target performance change rate and target height ratio are input into the remaining useful life determination model, which outputs the corresponding remaining useful life.

[0069] The method described above for determining the remaining service life of a bellows involves measuring the target temperature of the bellows under test. Based on the correlation between the temperature and the rate of performance change, the target performance change rate of the bellows at the target temperature can be determined. Then, the target height of the bellows is measured to determine the target height ratio. Finally, by analyzing the target performance change rate and the target height ratio, the remaining service life of the bellows can be accurately determined. Compared to traditional methods for determining the remaining service life of bellows, this approach eliminates the need to disassemble the bellows, avoiding the impact of disassembly on its performance and reducing labor costs. It provides a reasonable and accurate alternative for determining the remaining service life of bellows under test.

[0070] Optionally, based on the above embodiments, this embodiment further describes S204 in detail. For example... Figure 3 As shown, the specific implementation process includes the following steps:

[0071] S301, determine the adjustment height ratio based on the target height ratio and the life adjustment parameters of the bellows under test.

[0072] The life adjustment parameter is a constant value used to adjust the height ratio and is related to the material of the bellows; optionally, the life adjustment parameter is fixed for the same model of bellows.

[0073] Specifically, take the logarithm of the target height ratio of the bellows under test to obtain a logarithmic value; subtract this logarithmic value from the life adjustment parameter, and the difference is the adjustment height ratio.

[0074] S302, determine the remaining service life of the bellows under test based on the adjustment height ratio and the target performance change rate.

[0075] One alternative approach is to analyze data on the adjustment height ratio, performance change rate, and remaining service life of a large number of samples to determine a logic for determining the remaining service life. Then, based on this determined logic, the remaining service life of the bellows under test can be determined according to its adjustment height ratio and target performance change rate.

[0076] Another option is to use the ratio between the adjustment height ratio and the rate of change of the target performance as the remaining service life of the bellows under test.

[0077] Specifically, the ratio of the adjusted height to the target performance change rate is used to obtain a ratio, which is the remaining service life of the bellows under test.

[0078] In the above embodiments, by introducing a life adjustment parameter, the target height ratio is adjusted, and then the remaining service life of the bellows under test is determined based on the adjusted target height ratio, i.e., the adjusted height ratio, making the determination of the remaining service life more scientific and reasonable.

[0079] Optionally, based on 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 As shown, the specific steps include:

[0080] S401, based on the initial height and the test height of the standard corrugated pipe after different number of days of use at each test temperature, determines the rate of change of the test performance of the standard corrugated pipe at each test temperature.

[0081] The standard corrugated pipe and the corrugated pipe under test are of the same model.

[0082] An alternative approach is to determine, for each test temperature, the ratio of the test height of the standard corrugated pipe to the test height of different usage days at that test temperature, based on the initial height and the test height of the standard corrugated pipe at different usage days at that test temperature; and to determine the rate of change of the test performance of the standard corrugated pipe at that test temperature based on a general height ratio model and the ratio of the test height of the standard corrugated pipe at different usage days at that test temperature.

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

[0084] Specifically, for each test temperature, the test height of the standard corrugated pipe for each number of days at that test temperature can be divided by the initial height to obtain the ratio of the test height of the standard corrugated pipe for each number of days at that test temperature.

[0085] Then, taking the logarithm of the general height model yields a linear function Y = a + bX, where Y = lny, a = lnB, b = -K, X = τ, and a is the lifespan adjustment parameter, which is related to the constant B.

[0086] By substituting the ratio of the number of days of use to the corresponding test height at the test temperature into the aforementioned linear function, a system of equations can be obtained. Solving this system of equations using the least squares method yields the values ​​of 'a' and 'b' in the linear function. Based on the value of 'b', the rate of change in the test performance of the standard bellows at that test temperature can then be determined.

[0087] S402, based on the rate of change of the test performance of the standard bellows at each test temperature, determine the correlation between temperature and the rate of change of performance.

[0088] Alternatively, the performance change rates of a large number of standard corrugated pipes at different temperatures, along with the corresponding test temperatures, can be input into the SCILAB software. The SCILAB software then performs data analysis to determine the correlation between the performance change rate of the standard corrugated pipes and temperature. This correlation can be either a linear function or a quadratic function.

[0089] Another alternative approach is to determine the relationship between temperature and the rate of performance change based on the Arrhenius equation, according to the rate of performance change of a standard bellows at each test temperature.

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

[0091]

[0092] Where K is the rate of change 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, taking the logarithm of the Arrhenius equation yields a linear equation in one variable. Substituting multiple sets of test temperature and test performance change rate data into the equation results in a system of equations. Solving the system of equations using the least squares method yields a function of the performance change rate versus temperature, i.e., the relationship between temperature and performance change rate.

[0094] In the above embodiments, the correlation between temperature and performance change rate was determined by using data such as the height ratio of the standard corrugated pipe, the number of days used, and temperature. This allows the determination of the remaining service life of the corrugated pipe under test to determine the performance change rate of the corrugated pipe under test at the current temperature simply by knowing the temperature. This is of great significance for subsequently determining the remaining service life of the corrugated pipe under test.

[0095] In one embodiment, such as Figure 5 As shown, a method for determining the remaining service life of a bellows is provided, and the specific implementation process may include:

[0096] S501, for each test temperature, based on the initial height and the test height of the standard corrugated pipe for different usage days at that test temperature, determines the ratio of the test height of the standard corrugated pipe for different usage days at that test temperature.

[0097] S502, based on the general height ratio model and the test height ratio of the standard corrugated pipe for different number of days of use at this test temperature, determine the rate of change of the test performance of the standard corrugated pipe at this test temperature.

[0098] S503 determines the correlation between temperature and performance change rate based on the test performance change rate of a standard bellows at each test temperature.

[0099] S504, obtain the target height of the bellows under test at the target temperature.

[0100] S505, determine the target height ratio based on the initial height and target height of the bellows to be tested.

[0101] S506 determines the target performance change rate based on the relationship between temperature and performance change rate, according to the target temperature.

[0102] S507 determines the remaining service life of the bellows under test based on the target performance change rate and the target height ratio.

[0103] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
