[0071] The above-mentioned abnormal test data may refer to operating data in which some test data collected during the expansion process deviate from the normal range or show abnormal patterns, such as abnormal pressure peaks, displacement stagnation, current surges, etc. Generally speaking, the above-mentioned abnormal test data can be used to reflect abnormal conditions such as abnormal load, poor lubrication or component failure during the expansion process.

[0077] In an embodiment of the present invention, a preset simulation loading device is used to perform an expansion operation on a target expanding head, and performance test data of the target expanding head is collected in real time; the performance test data is analyzed to determine at least one corresponding abnormal test data; based on at least one abnormal test data, the corresponding performance adjustment parameters of the target expanding head during the expansion operation are determined; and based on the performance adjustment parameters, the performance parameters of the target expanding head during the expansion operation are adjusted. By performing real-time monitoring and analysis of key performance parameters during the expansion process through the above method steps, it is possible to identify and locate the source of the problem when the expanding head has an abnormal operating state, and then dynamically adjust the expansion speed, expansion stroke, thrust setting or lubrication control strategy based on the identification results, thereby achieving closed-loop optimization control of the expansion process and improving the accuracy and efficiency of the expansion process.
[0078] Optionally, in the steps before performing the expansion action on the target expanding head through a preset simulation loading device and collecting the performance test data of the target expanding head in real time, the surface of the target expanding head can also be identified through a preset camera module to determine the oil film data on the surface of the target expanding head; determine the oil output and oil pressure of the lubricating oil; determine the lubrication degree of the target expanding head based on the oil output, oil pressure, oil film uniformity and oil film thickness of the lubricating oil; if the lubrication degree reaches the preset expansion condition, the expansion action is performed on the target expanding head through the preset simulation loading device.
[0079] In an embodiment of the present invention, the above-mentioned preset camera module can be a high-definition image acquisition device installed near the working area of the expanding head and used to obtain the surface image of the expanding head. Generally speaking, the preset camera module can be called during the lubrication detection stage and perform real-time imaging scanning on the surface of the expanding head to provide basic image information for subsequent oil film identification and image analysis.
[0080] In a possible embodiment, the above-mentioned multimodal mechanical performance test management system analyzes and processes the surface image of the expanding head captured by the preset camera module through image processing and analysis algorithms, and extracts the oil film distribution characteristic information therein, such as the information set about the lubricating oil layer on the surface of the expanding head obtained by image recognition, which is mainly used to measure the oil film data of the lubrication state, including but not limited to oil film uniformity and oil film thickness, etc., which are used to evaluate the existence, distribution range, thickness change and oil film quality data.
[0081] Specifically, the above-mentioned oil film uniformity refers to the overall consistency of the distribution of lubricating oil on the surface of the expansion head, which is usually obtained based on the analysis of image brightness distribution, color density or reflection difference. Generally speaking, the better the uniformity, the more consistent the oil film brightness.
[0082] The above-mentioned oil film thickness can be indirectly estimated by grayscale estimation or laser ranging through image analysis algorithms to determine the vertical thickness of the lubricating oil layer on the surface of the target expanding head.
[0083] The above-mentioned oil output refers to the volume or mass of lubricating oil delivered to each lubrication point of the expansion head by the lubrication system per unit time, usually measured in mL / min or g / min. The above-mentioned oil output pressure refers to the pressure value of the lubricating oil in the lubrication system during the delivery process, usually expressed in MPa or bar, and monitored in real time by a pressure sensor.
[0084] The above-mentioned lubrication degree can be a comprehensive evaluation result of the current lubrication state of the expanding head calculated by the above-mentioned multimodal mechanical performance test management system based on multiple parameters such as oil film data, oil output and oil output pressure. Generally speaking, the above-mentioned lubrication degree can be divided into multiple levels (such as sufficient, critical, insufficient), which is one of the control conditions used to determine whether the expansion action is allowed to start, and can provide feedback on the expansion of the target expanding head under the current expansion conditions.
[0085] The above-mentioned preset expansion conditions may refer to the lubrication state threshold conditions required by the above-mentioned multimodal mechanical performance test management system before performing the expansion action, which may generally include but are not limited to thresholds such as minimum oil film thickness, minimum oil output, minimum oil output pressure and oil film uniformity standards.
[0086] In a possible embodiment, the above-mentioned multimodal mechanical property test management system collects and identifies images of the target expanding head surface through a preset camera module before executing the expansion action, extracts oil film data such as oil film thickness and uniformity, and comprehensively judges the lubrication degree of the expanding head in combination with the oil output and oil output pressure of the lubrication system; only when the lubrication degree reaches the preset expansion condition, the simulation loading device is started to execute the expansion action.
[0087] The above method and steps can effectively simulate and avoid the expansion operation under insufficient lubrication state, reduce the risk of friction and wear, and improve the stability of the expansion process and the service life of the expansion head.
[0088] Optionally, in the step of performing an expanding action on the target expanding head through a preset simulation loading device and collecting performance test data of the target expanding head in real time, it also includes collecting pressure data of the target expanding head through a preset pressure sensor to determine the pressure data of the expanding action on the target expanding head; collecting displacement data of the target expanding head through a preset displacement sensor to determine the displacement data of the expanding action on the target expanding head; and analyzing the expanding thrust and displacement information according to the preset electric drive load to determine the corresponding current data.
[0089] In an embodiment of the present invention, the above-mentioned preset pressure sensor may refer to a pressure detection element installed in the hydraulic circuit of the expansion system, which is usually arranged at the hydraulic interface of the main oil cylinder and the preset simulation loading device, and is used to sense the oil pressure changes during the expansion process in real time. Its output signal can accurately reflect the axial thrust currently exerted on the expansion head.
[0090] Specifically, the hydraulic data generated during operation can be continuously sampled and recorded through the above-mentioned preset pressure sensor. It can be understood that it can be controlled by a PLC or data acquisition module, and the acquisition frequency can reach milliseconds, which is used to construct a time series of thrust changes during the expansion process.
[0091] The above-mentioned pressure data may refer to the working pressure value of the hydraulic system measured by the pressure sensor during the expansion action, reflecting the thrust strength borne by the expansion head at each moment.
[0092] The above-mentioned preset displacement sensor can refer to a displacement measuring element installed on the axial motion path of the expanding head. Common forms include LVDT linear displacement sensor, grating scale or magnetic encoder, which is used to record the linear displacement position of the expanding head in real time to form displacement trajectory data of the entire expanding action process.
[0093] Specifically, the preset displacement sensor can be used to monitor the movement process of the expanding head in real time and obtain its position change data, and monitor whether the expanding stroke is continuous and the speed is stable.
[0094] The above displacement data may be a set of values of the position of the expanding head at each moment during the expansion process, and is usually organized in a time series.
[0095] The above-mentioned preset electric drive load may refer to the target electric drive power or load state set during the test or operation of the expansion device, which is used to simulate actual working conditions or control experimental variables.
[0096] The above-mentioned expansion thrust can be the axial force applied by the target expanding head to the inner wall of the workpiece during the expansion process, which is usually obtained by converting the cylinder pressure through the piston area. Since excessive expansion action may cause structural damage, and excessive expansion action may result in insufficient expansion, the expansion thrust can be determined by the above-mentioned method steps.
[0097] The above-mentioned displacement information may refer to real-time position change data during the expansion action, including comprehensive parameters such as the current displacement value, movement direction, stroke start and end points, and movement speed.
[0098] In a possible embodiment, the above-mentioned multimodal mechanical performance test management system processes and judges the current expansion state based on the collected pressure data, displacement information and electric drive settings through a control algorithm or data model, which may include but is not limited to peak detection, fluctuation trend identification, power calculation and other detection items, which are used to deduce current data or identify abnormal conditions.
[0099] In another possible embodiment, the multimodal mechanical property test management system simulates the target expanding head to perform the expansion action, and collects the pressure data and displacement data generated during the expansion process through preset pressure sensors and displacement sensors respectively, and combines the set electric drive load to perform a comprehensive analysis of the expansion thrust and displacement information, and calculates the corresponding current data to reflect the load response of the drive system.
[0100] Through the above-mentioned method and steps, real-time monitoring and feedback of multimodal mechanical data during the diameter expansion process are achieved, which helps to accurately identify diameter expansion anomalies, optimize energy consumption control, and improve the reliability and accuracy of diameter expansion testing.
[0101] Optionally, in the step of analyzing the performance test data and determining at least one corresponding abnormal test data, the step also includes comparing the pressure data with a preset pressure threshold to determine the corresponding pressure abnormality test data; performing linear change detection on the displacement data, and if there is a linear change, determining the corresponding displacement abnormality test data; and performing real-time monitoring on the current data, and if an instantaneous fluctuation state or a continuous climbing state occurs, determining the corresponding current abnormality test data.
[0102] In an embodiment of the present invention, the above-mentioned preset pressure threshold may refer to the pressure upper limit value or interval threshold value set in advance by the above-mentioned multimodal mechanical performance test management system based on the structural design of the expansion equipment, historical test data, material properties and other data, which is used to determine whether the loading is abnormal during the expansion process. It can be understood that the above-mentioned preset pressure threshold can be stored in the system database, automatically called by the controller during the data acquisition process, and compared with the real-time acquired pressure data. The above-mentioned pressure data can be collected in real time by the pressure sensors installed at both ends of the expansion cylinder, and the output standard analog signal or digital signal is input into the data acquisition card or PLC module.
[0103] The aforementioned abnormal pressure test data may refer to pressure values collected by the aforementioned multimodal mechanical properties test management system during the expansion process that do not meet a preset pressure threshold. For example, when the pressure exceeds the upper threshold, it may indicate excessive expansion resistance, mechanical jamming, or other issues. It is understood that this data can be collected by the aforementioned pressure sensor, and the control system can determine in real time whether it falls within the abnormal range, automatically marking it as abnormal and recording it in a log or alarm module.
[0104] In one possible embodiment, trend analysis can be performed on the displacement data of the expanding head during the expansion process to determine whether it exhibits a stable linear increase over time, consistent with a normal expansion rhythm, thereby achieving the purpose of detecting linear changes in the target expanding head. Specifically, this can be achieved using time-series displacement data, using a sliding window or linear regression algorithm. Displacement sensors (such as LVDTs or magnetic scales) mounted on the expansion mechanism acquire the corresponding displacement data. The displacement signals output by the sensors are then collected and input into a higher-level control system for continuous trend analysis.
[0105] The above-mentioned displacement abnormality test data may refer to data showing a significant deviation between the actual running trajectory of the target expansion head and the expected trajectory of linear expansion. Common abnormal manifestations include displacement stagnation, regression, overshoot, etc. Generally speaking, displacement data can be collected by a displacement sensor and uploaded to the control system in real time. The built-in linear trend detection module will analyze and determine whether it constitutes an abnormality. Once identified, it will be automatically recorded and marked.
[0106] The above-mentioned transient fluctuation state may refer to the phenomenon that the current signal changes dramatically in an extremely short period of time (such as tens of milliseconds), which usually indicates that the drive system encounters sudden resistance or load changes. The current of the expansion drive motor can be collected in real time through a high-frequency current sensor (such as a Hall current sensor).
[0107] The above-mentioned continuous climbing state may refer to the current value continuously increasing during the expansion process and maintaining a trend without decreasing for a long time, reflecting problems such as the continuous increase in the expansion load or the increase in friction caused by lubrication failure. Specifically, the current can be collected and provided by the current sensor or inverter feedback module in the motor power supply circuit. The above-mentioned multimodal mechanical performance test management system records it at a certain sampling frequency and determines whether the climbing trend meets the abnormal conditions through moving average or gradient analysis. It is understandable that if the current collection results of instantaneous fluctuations or continuous climbing states appear during the expansion process, it means that the expansion system has load imbalance or unstable response of the electric drive system in a certain period of time. At this time, the current data is determined to be current abnormality test data.
[0108] In a possible embodiment, the above-mentioned multimodal mechanical performance test management system collects multimodal performance data such as pressure, displacement and current in real time during the expansion process, and performs intelligent analysis through a set abnormality recognition mechanism: including comparing the pressure data with a preset pressure threshold to identify abnormal loading conditions; performing linear change detection on the displacement data to determine whether there is displacement stagnation or offset; and identifying instantaneous fluctuations and continuous climbs in the current data to detect abnormal load or energy consumption conditions.
[0109] Through the above-mentioned method and steps, various types of anomalies in the expansion process can be accurately identified, the expansion fault warning capability and test response efficiency can be effectively improved, and the stability of the test system operation and the accuracy of data analysis can be ensured.
[0110] Optionally, in the step of determining the performance adjustment parameters corresponding to the target expanding head during the expansion work based on at least one abnormal test data, it also includes determining the corrected thrust data corresponding to the expansion adjustment when abnormal pressure test data is detected; determining the corrected stroke limit data corresponding to the expansion adjustment when abnormal displacement test data is detected; determining the corresponding lubrication correction parameter corresponding to the expansion adjustment when abnormal current test data is detected; and determining the performance adjustment parameters corresponding to the target expanding head during the expansion work based on at least one of the corrected thrust data, the corrected stroke limit data and the lubrication correction parameter.
[0111] In an embodiment of the present invention, the performance adjustment parameters can be used to correct abnormal expansion movements of the target expanding head during expansion work by correcting thrust data, correcting stroke limit data, and lubrication correction parameters.
[0112] Specifically, the corrected thrust data may be a corrected thrust value for controlling the loading device that is recalculated based on a deviation between a target thrust curve and actual data after identifying a pressure anomaly during the expansion process.
[0113] The above-mentioned corrected stroke limit data can be a new stroke end point or limit interval set according to the standard action range after identifying abnormal displacement of the expanding head (such as insufficient stroke, overshoot, etc.), which is used to adjust the maximum or minimum movable distance of the expanding head.
[0114] The above-mentioned lubrication correction parameter may refer to a lubrication strategy parameter adjustment value calculated in response to an abnormal current state (usually an abnormal load) occurring during the expansion process, such as adjusting the lubricating oil supply pressure, oil volume, injection interval, or viscosity selection.
[0115] In one possible embodiment, when the multimodal mechanical performance test management system identifies a pressure anomaly, it compares the current thrust curve with the target thrust curve and calculates a corrected loading curve. The servo hydraulic drive device controls the valve group and converts the corrected thrust data into an opening instruction for adjusting the hydraulic proportional valve, thereby dynamically adjusting the loading speed and pressure value of the expansion cylinder to achieve soft adjustment of the thrust.
[0116] When the multimodal mechanical properties test management system detects abnormal displacement (such as expansion head advancement not meeting standards or overshoot), it generates a corrected stroke boundary by analyzing the deviation between the real-time displacement and the expected curve. This data is sent to the expansion head control unit or PLC, which dynamically updates the upper limit of the displacement sensor or the stop position threshold, thereby adjusting the end stop position or the return starting point in the next expansion step.
[0117] When the above-mentioned multimodal mechanical performance test management system detects an abnormal current, it is judged that the expansion head drive mechanism has excessive friction or insufficient lubrication, and the lubrication coefficient is adjusted by correcting the parameters, which may include increasing the oil supply pressure, increasing the oil output frequency, or switching to a higher viscosity lubricant. Finally, the lubrication correction parameter is transmitted to the electric lubrication pump control unit linked to it to achieve dynamic adjustment of the lubrication status.
[0118] Through the above-mentioned dynamic correction execution mechanism of thrust, stroke and lubrication, the multimodal mechanical performance test management system not only realizes abnormal self-perception, self-correction and adaptive control during the diameter expansion test, but also improves the accuracy of the diameter expansion action and the stability of equipment operation.
[0119] Optionally, in the step of adjusting the performance parameters of the target expanding head during the expansion work based on the performance adjustment parameters, it also includes adjusting the thrust output and expansion speed of the target expanding head based on the corrected thrust data; adjusting the expansion stroke length of the target expanding head or determining the segmented expansion strategy based on the corrected stroke limit data; and adjusting the oil output, oil output pressure and lubrication mode of the lubricating oil based on the lubrication correction parameters.
[0120] In an embodiment of the present invention, the above-mentioned lubrication mode may include but is not limited to continuous lubrication and intermittent lubrication modes for adjusting the lubrication coefficient. Generally speaking, the lubrication coefficient can be changed by controlling the oil output and oil output pressure.
[0121] The above-mentioned thrust output may refer to the axial force applied to the expanding head by the expansion drive mechanism (such as a hydraulic cylinder, an electric servo device, etc.) during the expansion process, which is used to push the expanding head to radially deform the processed pipe or component. Its unit is usually kilonewton (kN), which is used to influence and feedback the expansion deformation effect and load matching control.
[0122] The expansion speed, typically measured in millimeters per second (mm / s), refers to the linear velocity of the expanding head's axial movement during the expansion process. This parameter determines the rhythm and deformation rate of the expansion process. Excessively fast expansion speeds can lead to stress concentration and material fracture, while excessively slow expansion speeds can affect test efficiency and equipment response. Specifically, controlling the expansion speed allows for optimal coordination of factors such as material rebound, stress release, and lubrication status.
[0123] The aforementioned segmented expansion strategy refers to a control method that divides the overall expansion stroke into multiple stages. Different thrust values, speeds, and stop positions are set for each stage to achieve step-by-step, segmented expansion process control. For example, when performing an expansion test on a stainless steel pipe with a total expansion stroke of 100mm, the system detects that a one-time expansion may result in uneven material wall thickness or stress concentration. Therefore, the segmented expansion strategy is activated, dividing the overall expansion process into three stages:
[0124] Stage 1: The propulsion stroke is 0–40 mm, the thrust is set to 80 kN, and the expansion speed is 2 mm / s to ensure uniform initial deformation;
[0125] Stage 2: Push the stroke to 40–70 mm, appropriately reduce the expansion speed to 1.5 mm / s, and increase the thrust to 90 kN to overcome the resistance in the middle of the material;
[0126] The third stage: the stroke is advanced to 70–100 mm, the speed is further reduced to 1 mm / s, and the continuous lubrication mode is enabled to reduce friction and heat, finally completing the entire diameter expansion process.
[0127] During the entire process, a pause of several seconds is performed after each stage to collect sensor data and determine whether to terminate the process early or dynamically adjust the parameters of the next stage.
[0128] The multi-stage progressive expansion strategy mentioned above reduces instantaneous load impact, improves forming accuracy, and effectively controls the risk of material rebound and cracks.
[0129] In a possible embodiment, after obtaining the performance adjustment parameters, the above-mentioned multimodal mechanical performance test management system performs corresponding dynamic correction control based on different types of abnormal test data: when a pressure abnormality is identified, the thrust output size and expansion speed of the expansion head are adjusted to achieve smooth loading; when a displacement abnormality is identified, the expansion stroke length is reset, or a segmented expansion strategy is enabled to reduce structural stress concentration; when a current abnormality is identified, the system adjusts the oil output, oil output pressure and lubrication mode (including continuous lubrication and intermittent lubrication) of the lubricating oil to optimize the friction state.
[0130] Through the above method and steps, automatic correction and real-time adjustment of the diameter expansion action parameters are achieved, thereby improving the safety and accuracy of the diameter expansion process.
