Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only.

[0024] This application provides a twin correction method and system for the aging performance of adhesives, such as... Figure 1 As shown, the method includes: Multiple aging conditions are introduced for the adhesive. Based on these conditions, data sensing is performed on the adhesive to determine multiple actual aging performance data. These aging conditions are then synchronized to a simulation model for performance simulation, generating a performance simulation dataset. A Siamese network is constructed using deep learning. The multiple actual aging performance data and the performance simulation dataset are transmitted to the Siamese network for processing to obtain multiple performance error coefficients.

[0025] To assess the aging performance of adhesives, multiple aging conditions need to be introduced, including temperature, humidity, UV radiation intensity, oxygen concentration in the air, and corresponding time. These aging conditions correspond to the application conditions of the adhesive in actual use. Actual aging performance data of the adhesive under these conditions are tested, including bond strength, tensile strength, and fracture toughness. Furthermore, these aging conditions are synchronized to a simulation model for performance simulation, generating a performance simulation dataset. The simulation model is a virtual model built using computer software based on finite element analysis tools, used to simulate the physical processes of the adhesive under multiple aging conditions and predict the performance data of the adhesive under different aging conditions, thereby generating the performance simulation dataset.

[0026] Furthermore, a Siamese network is constructed based on deep learning technology. The Siamese network consists of two sub-networks: a data simulation network and a data monitoring network, which respectively process the performance simulation dataset and multiple actual aging performance data. The Siamese network is constructed based on actual aging performance data over a full time period under different aging conditions in historical records, as well as the performance simulation dataset over a full time period. The actual aging performance data over a full time period includes bond strength, tensile strength, and fracture toughness data recorded at each time period node. The performance simulation dataset over a full time period includes bond strength, tensile strength, and fracture toughness data output from performance simulations performed by the simulation model at each time period node. Subsequently, the actual aging performance data under different aging conditions and corresponding full time periods are input into the deep neural network model for training. The model learns the time dependence and physical characteristics in the simulation data to predict the future aging performance of the adhesive until the model training is complete, thus obtaining the data monitoring network. Using the same construction method, the performance simulation dataset under different aging conditions and corresponding full time periods is used as training data to construct the data simulation network. Furthermore, the multiple actual aging performance data and the performance simulation dataset are transmitted to the Siamese network for processing to obtain multiple performance error coefficients.

[0027] The method provided in this application embodiment further includes: the twin network comprising a data simulation network and a data monitoring network. Simulation output is generated based on the data simulation network and the performance simulation dataset to produce simulation performance prediction results. Monitoring output is generated based on the data monitoring network and the multiple actual aging performance data to produce an actual aging performance parameter set. The simulation performance prediction results are compared with the actual aging performance parameter set according to a self-check cycle to generate multiple performance error coefficients.

[0028] The twin network comprises a data simulation network and a data monitoring network. Based on the data simulation network, aging conditions are simulated using the performance simulation dataset to predict the aging process of the adhesive, outputting simulation performance prediction results. These results include predicted parameters for bond strength, tensile strength, and fracture toughness at multiple future time points. Based on the data monitoring network, aging conditions are monitored using the multiple actual aging performance data to generate an actual aging performance parameter set. This set includes parameters for bond strength, tensile strength, and fracture toughness monitored at multiple future time points. The simulation performance prediction results are compared with the actual aging performance parameter set according to a self-checking cycle to generate multiple performance error coefficients.

[0029] The method provided in this application embodiment further includes: defining multiple application scenario parameters for the adhesive based on the multiple aging conditions, and setting the self-test cycle according to the multiple application scenario parameters. Iterating through the simulation performance prediction results and the actual aging performance parameter set to perform performance matching, and determining multiple sets of prediction-actual performance data pairs. Defining a loss function, and calculating for each set of prediction-actual performance data pairs according to the self-test cycle and the loss function, generating a performance error report. Performing error analysis based on the performance error report, and constructing an error trend graph. Identifying the error coefficients of each set of prediction-actual performance data pairs according to the error trend graph, and obtaining the multiple performance error coefficients.

[0030] Multiple application scenario parameters for the adhesive are defined based on the aforementioned aging conditions. A self-inspection cycle is set according to these parameters, which represent various environmental or operational conditions the adhesive may encounter during actual use, such as aging conditions like temperature, humidity, and ultraviolet radiation. The self-inspection cycle is set by professional technicians based on the actual application scenario parameters and can be every 12 hours, 24 hours, or weekly. A higher frequency of the cycle ensures more timely correction of the simulation model. Subsequently, the simulation performance prediction results are iterated and matched with the actual aging performance parameter set to determine multiple sets of prediction-actual performance data pairs. These pairs are the pairings between the adhesive performance data predicted by the simulation model and the actual aging performance data at corresponding time points, used to analyze the difference between prediction and reality. Each prediction-actual performance data pair consists of all data pairs for a single performance parameter. Furthermore, a loss function is defined as the ratio of the difference between the predicted and actual data in multiple sets of predicted-actual performance data pairs to the actual aging performance data. The loss function is applied to each set of predicted-actual performance data according to the self-inspection cycle, generating a performance error report. This report includes the error ratio parameter for each set of predicted-actual performance data pairs within the self-inspection cycle. Error analysis is performed based on the performance error report, and an error trend graph is constructed, recording the trend of error parameters changing over time. Finally, based on the error trend graph, the error coefficient for each set of predicted-actual performance data pairs is identified. The error coefficient is the slope of the error trend graph in each self-inspection cycle.

[0031] The simulation model is dynamically corrected according to the multiple performance error coefficients to obtain a corrected simulation model. The performance simulation dataset is then corrected using this corrected model, and the Siamese network is optimized based on the corrected performance simulation dataset to generate an optimized Siamese network.

[0032] The simulation model is dynamically corrected according to the multiple performance error coefficients to obtain a corrected simulation model. Further, the performance simulation dataset is corrected using the corrected simulation model to obtain corrected data. A Siamese network is then trained, validated, and tested based on the corrected performance simulation dataset to generate an optimized Siamese network. Finally, the optimized Siamese network is used to accurately predict the adhesive performance under different aging conditions. This solves the technical problems of low acquisition efficiency and difficulty in accurately predicting adhesive performance under different aging conditions in existing technologies. It improves the accuracy and efficiency of predicting adhesive performance under different aging conditions.

[0033] The method provided in this application embodiment further includes: performing continuous analysis based on the error trend graph and the multiple performance error coefficients to determine multiple continuously changing deviation points; performing source tracing and classification based on the multiple continuously changing deviation points to obtain multiple error sources; traversing the simulation model according to the multiple error sources, formulating a correction strategy, executing the correction strategy to dynamically correct the simulation model, and generating the corrected simulation model.

[0034] The simulation model is dynamically corrected according to the multiple performance error coefficients to obtain a corrected simulation model. The method includes: continuously analyzing the error trend chart in conjunction with the multiple performance error coefficients to determine multiple continuously changing deviation points. These continuously changing deviation points are the time nodes corresponding to the self-inspection cycle in which the error coefficient increases compared to the previous self-inspection cycle. The existence of multiple continuously changing deviation points indicates that the simulation model has a systematic bias in its prediction of the corresponding parameters, requiring focused correction. Further, technical personnel identify the specific sources of error for each of the multiple continuously changing deviation points, such as environmental factors like temperature. Based on these multiple continuously changing deviation points, source tracing and classification are performed to obtain multiple error sources. These error sources include: material parameter errors: such as inaccurate settings in the simulation model regarding the physical properties of adhesive materials (e.g., elastic modulus, shear strength); environmental factor errors: such as the effects of environmental conditions like temperature and humidity not being fully reflected in the simulation model; and time-dependent errors: such as the time-dependent aging process of adhesives, where the simulation model cannot accurately capture the trend of performance changes over time. The simulation model is iterated through according to the multiple error sources, a correction strategy is formulated, the correction strategy is executed to dynamically correct the simulation model, and the corrected simulation model is generated.

[0035] The method provided in this application embodiment further includes: traversing the simulation model based on the multiple error sources, and determining whether there are nodes in the simulation model that are greater than or equal to the expected simulation threshold. If there are nodes in the simulation model that are greater than or equal to the expected simulation threshold, then multiple nodes to be corrected are extracted. Dynamic correction instructions are generated based on the multiple error sources and the multiple performance error coefficients. The dynamic correction instructions are added to the correction strategy to dynamically mark the multiple nodes to be corrected, generating error distribution data. A performance parameter space is constructed, and the performance parameter space is dynamically searched according to the error distribution data. The simulation model is updated and corrected according to the search results to obtain the corrected simulation model.

[0036] The simulation model is traversed based on the multiple error sources to formulate a correction strategy. This correction strategy is then executed to dynamically correct the simulation model, generating a corrected simulation model. The method includes: after generating multiple performance error coefficients, the system traverses the simulation model, checking each node in the model one by one, and determining whether there are any nodes in the simulation model that are greater than or equal to a desired simulation threshold. The desired simulation threshold is a pre-set error coefficient judgment standard, based on the performance error coefficients. If the error between the simulation result and the actual data is greater than this threshold, the node needs to be corrected. If there are nodes in the simulation model greater than or equal to the desired simulation threshold, multiple nodes to be corrected are extracted. These multiple nodes to be corrected are multiple data nodes within the continuously changing deviation point detection period. Further, dynamic correction instructions are generated based on the multiple error sources and the multiple performance error coefficients. These dynamic correction instructions are specific instructions used to correct the nodes to be corrected in the simulation model, including the error sources and performance error coefficients, with the aim of adjusting the node parameters to make the simulation results closer to the actual data. The dynamic correction instructions are added to the correction strategy to dynamically mark the multiple nodes to be corrected, marking the correction strategies corresponding to the multiple nodes to be corrected, and generating error distribution data. The error distribution data contains the nodes to be corrected and their corresponding correction strategies. A performance parameter space is constructed, and the performance parameter space is dynamically searched according to the error distribution data to obtain the actual aging performance data corresponding to the error distribution data in the performance parameter space. Based on the search results, the simulation model is updated and corrected according to the actual aging performance data to obtain the simulation correction model.

[0037] The method provided in this application embodiment further includes: analyzing the multiple actual aging performance data to determine the spatial dimension, discretizing the data according to the spatial dimension to generate multiple discrete sample values; combining the discrete sample values ​​of each spatial dimension to construct a multi-dimensional parameter space; and mapping the multiple actual aging performance data to the multi-dimensional parameter space based on the multiple application scenario parameters to construct the performance parameter space.

[0038] The method for constructing the performance parameter space includes: analyzing multiple actual aging performance data to determine spatial dimensions. These spatial dimensions represent key parameters affecting adhesive aging, including temperature, humidity, UV intensity, stress, and time, as well as performance parameters such as bond strength, tensile strength, and fracture toughness. Subsequently, each spatial dimension is discretized, dividing a continuous parameter range into multiple fixed values ​​as discrete sample values, generating multiple discrete sample values. Each combination of sample values ​​represents a specific aging parameter and forms a point in the parameter space. Based on the multiple application scenario parameters, the multiple actual aging performance data are mapped to the multidimensional parameter space to obtain corresponding parameter space points. The performance parameter space containing all parameter space points is then constructed based on these parameter space points.

[0039] The method provided in this application embodiment further includes: dividing the performance simulation correction dataset into an optimized training dataset, an optimized validation dataset, and an optimized test dataset. Backpropagation is performed on the Siamese network using the optimized training dataset. Based on the backpropagation results, the weights of the data simulation network and the data monitoring network are updated to generate multiple weight coefficients. The data simulation network and the data monitoring network are evaluated using the optimized validation dataset in conjunction with the multiple weight coefficients. Based on the evaluation results, the Siamese network is dynamically adjusted to generate a Siamese network adjustment result. Based on the optimized test dataset, the Siamese network adjustment result is adaptively tested in conjunction with a learning rate strategy. When the test passes, the optimized Siamese network is generated.

[0040] The performance simulation dataset is corrected using the simulation correction model. The Siamese network is then optimized based on the corrected performance simulation dataset to generate an optimized Siamese network. The method includes: partitioning the performance simulation correction dataset to determine an optimized training dataset, an optimized validation dataset, and an optimized test dataset. These datasets are used for training, validating, and testing the Siamese network, respectively, to ensure the model's accuracy and generalization ability. After the dataset partitioning, the Siamese network is trained using the optimized training dataset. During training, the backpropagation algorithm is used to update the weights of the data simulation network and the data monitoring network based on the model's output error. Finally, multiple new weight coefficients are generated to improve the Siamese network's performance. Backpropagation is an optimization algorithm that calculates the network's output error and propagates it back to each layer of the network, thereby adjusting the network's weights and gradually reducing the prediction error. The Siamese network is evaluated using the optimized validation dataset to test its performance on data not used in training. The evaluation aims to determine whether the network is overfitting or underfitting, ensuring that the model's performance on new data is consistent with its performance on training data. If network performance deteriorates during the evaluation process, the Siamese network needs to be dynamically adjusted. This involves adjusting the model's training parameters in real time based on the evaluation results of the validation set to improve its generalization ability. After dynamic adjustment of the Siamese network, adaptive testing is performed using an optimized test dataset. Adaptive testing, combined with a learning rate strategy, dynamically adjusts the model's learning rate based on its performance on the test set, ensuring the model's learning efficiency at different stages. After adaptive testing on the optimized test dataset confirms stable network performance, the final optimized Siamese network is generated. This optimized network can more accurately predict the performance of adhesives under different aging conditions and has good generalization ability, making it suitable for various application scenarios.
