Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figures 1 to 6 As shown, this embodiment provides a large-scale, multi-functional experimental device with multi-field coupling transparency, including:

[0039] The frame 1 is equipped with a loading component, which is used to perform multi-directional coupling loading on the material 5 to be tested.

[0040] Loading box 2 is a split design. Loading box 2 is clamped and fixed on frame 1 by a fixed frame 14 that is movably set on frame 1. Loading box 2 is provided with clamping components for clamping the test material 5 from multiple angles. The clamping components are connected to the loading components by transmission.

[0041] Environment coupling component 3 is installed on loading box 2 and is used to couple different environmental conditions in loading box 2.

[0042] Monitoring component 4 is configured to correspond with loading box 2 and is used to monitor the state of the material 5 to be tested.

[0043] This invention discloses a large-scale, multi-functional experimental device with multi-field coupling transparency. The device mainly consists of a frame 1, a loading chamber 2, an environmental coupling component 3, and a monitoring component 4. It integrates multiple functions such as loading, environmental simulation, and monitoring into a complete experimental system, improving experimental efficiency and reducing experimental costs. The frame 1 serves as the main supporting structure of the device, and the loading component is mounted on it. This component can perform multi-directional coupling loading on the test material 5, allowing the test material 5 to be subjected to forces simultaneously or sequentially in multiple dimensions to simulate stress conditions under complex environments. The loading chamber 2 adopts a split design, facilitating installation, disassembly, and maintenance, and making it convenient to place and remove the test material 5 from the loading chamber 2. The loading chamber 2 is clamped and fixed to the frame 1 by a movable bracket 14, improving the flexibility and adaptability of the device. The clamping assembly on loading chamber 2 clamps the test material 5 from multiple angles, ensuring the stability of the material during the experiment. It is also connected to the loading assembly via a transmission mechanism, enabling precise transmission and control of the loading force. The split-type loading chamber 2 and the multi-angle clamping capability of the clamping assembly allow the equipment to adapt to the testing needs of large-scale materials, broadening the applicability of the experimental equipment. The environmental coupling assembly 3 is located on loading chamber 2, creating and coupling different environmental conditions inside loading chamber 2, such as temperature, humidity, pressure, and electromagnetic fields, to simulate various environments that the material may encounter in practical applications, thereby providing a more comprehensive evaluation of the material's performance. The monitoring assembly 4 is located outside loading chamber 2 and corresponds to it. It can monitor the state changes of the test material 5 in real time during the experiment, realizing real-time monitoring of the material's state, such as stress distribution, deformation, and damage development. This provides important evidence for the collection and analysis of experimental data, enabling immediate analysis of experimental data and helping researchers quickly obtain experimental results, adjust experimental parameters, and optimize experimental plans. The test material 5 inside the loading chamber 2 is subjected to multi-directional coupling loading by the loading component and environmental condition simulation by the environmental coupling component 3. This enables performance testing of the material under multi-field coupling conditions, more closely resembling the complex stress and environmental states of the material in actual applications, thus improving the accuracy and reliability of experimental results. This invention integrates loading, environmental simulation, and monitoring functions into a complete experimental system, improving experimental efficiency and reducing costs; it can simulate complex stress environments, improving the accuracy and reliability of experimental results; and it is suitable for large-scale material testing, broadening its applicability.

[0044] In one embodiment of the present invention, the frame 1 includes a base 11 fixed to the ground to provide a stable foundation for the device; two parallel columns 12 are provided on the base 11, and a movable beam 13 that can be adjusted longitudinally is provided between the two columns 12; the loading components at the upper and lower ends are respectively installed on the two movable beams 13, which can be adapted to different loading boxes 2.

[0045] In one embodiment of the present invention, an adjustment motor 15 is provided on the movable beam 13, and the adjustment motor 15 can provide power for the adjustment of the movable beam 13.

[0046] The design is further optimized. The loading chamber 2 includes an upper chamber 21 and a lower chamber 22, which are detachably connected. A cooling component for temperature regulation is designed between the upper chamber 21 and the lower chamber 22. The detachable connection of the upper chamber 21 and the lower chamber 22 forms the loading chamber 2. When loading the material 5 to be tested, the upper chamber 21 and the lower chamber 22 are disassembled, the material is placed in, and then they are reassembled. This facilitates the loading and unloading of the material 5 to be tested and the maintenance of the equipment. The loading chamber 2 is sealed and independent. The cooling component can effectively regulate the temperature inside the loading chamber 2, improving the control capability of the temperature environment, enhancing the equipment's ability to simulate complex environments, and enriching the types of environmental simulations.

[0047] In one embodiment of the present invention, the loading box 2 is made of a material with good heat insulation effect to avoid the influence between the internal and external temperatures.

[0048] The cooling system is further optimized by including a cooling inlet 23 and a cooling outlet 24. The cooling inlet 23 is located on the lower housing 22 and communicates with the lower cooling chamber 25 on the lower housing 22. The cooling outlet 24 is located on the upper housing 21 and communicates with the upper cooling chamber 26 on the upper housing 21. The upper cooling chamber 26 communicates with the lower cooling chamber 25. When it is necessary to adjust the temperature inside the loading chamber 2, especially when it is necessary to cool the environment inside the loading chamber 2, the cooling medium enters the lower cooling chamber 25 from the cooling inlet 23, then flows into the upper cooling chamber 26, and finally flows out from the cooling outlet 24, flowing from low to high. This cycle achieves temperature regulation of the loading chamber 2, improving temperature regulation efficiency and uniformity.

[0049] Further optimization of the design involves an insertion slot 27 at the top of the lower housing 22 and a connector 28 at the bottom of the upper housing 21 that matches the insertion slot 27. The connector 28 is sealed and inserted into the insertion slot 27. The upper cooling chamber 26 passes through the connector 28, and the insertion slot 27 communicates with the lower cooling chamber 25. When the connector 28 is inserted into the insertion slot 27, the upper cooling chamber 26 and the lower cooling chamber 25 are connected. When installing the loading box 2, the connector 28 of the upper housing 21 is inserted into the insertion slot 27 of the lower housing 22, facilitating installation and disassembly and improving equipment flexibility. The inserted connector 28 and insertion slot 27 connect the upper cooling chamber 26 and the lower cooling chamber 25, preventing cooling medium leakage and ensuring smooth communication of the cooling chambers, guaranteeing smooth circulation of the cooling medium. Simultaneously, a sealed connection between the upper and lower housings 22 is achieved, preventing the loading box 2 from interacting with the external environment and ensuring an independent environment within the loading box 2.

[0050] In one embodiment of the present invention, a sealing gasket 29 is provided on the contact surface between the upper box 21 and the lower box 22. The sealing gasket 29 can work normally under the selected experimental environment, ensuring the sealed connection between the upper box 21 and the lower box 22.

[0051] In one embodiment of the present invention, a drain port 34 is provided at the bottom of the inner cavity of the lower box 22 for draining accumulated sewage, which facilitates cleaning of the loading box 2 before and after the experiment.

[0052] The design is further optimized. The clamping assembly includes several clamping rods 210 that slide and seal on each side of the loading box 2. One end of each clamping rod 210 extends out of the loading box 2 and is detachably driven by the loading assembly. A replaceable clamping head 212 is provided at the end of the clamping rod 210 furthest from the loading assembly. Several clamping heads 212 load the material 5 to be tested. The clamping rods 210 are connected to the loading box 2 via sealed bearings 211, allowing the clamping rods 210 to apply tension, compression, and torsion to the material 5 to be tested via the clamping heads 212. One end of the clamping rod 210 is driven by the loading assembly, driving the clamping heads 212 to load the material 5 to be tested, ensuring the sealing of the loading box 2. The clamping heads 212 at the ends of the clamping rods 210 can be quickly and flexibly replaced according to experimental needs, allowing for flexible adjustment of the loading method and clamping form based on different experimental requirements, thus improving the versatility and flexibility of the equipment.

[0053] The scheme is further optimized. The loading component includes a loading hydraulic cylinder 16 fixedly mounted on the frame 1. The output end of the loading hydraulic cylinder 16 faces through the frame 1 and towards the loading box 2. The output end of the loading hydraulic cylinder 16 is connected to the clamping rod 210 via a quick connector 17. When the loading hydraulic cylinder 16 is working, its output end drives the clamping rod 210 to move via the quick connector 17. The clamping head 212 then applies a loading force to the material 5 to be tested, making the loading force stable and controllable. The quick connector 17 facilitates the connection and disconnection of the output end of the loading hydraulic cylinder 16 and the clamping rod 210, improving the ease of operation and the reliability of loading.

[0054] The design was further optimized by providing an observation hole 213 through the lower housing 22. A transparent observation glass 214 was embedded within the observation hole 213, corresponding to both the monitoring component 4 and the test material 5. During the experiment, the monitoring component 4 observed the state of the test material 5 inside the loading chamber 2 through the observation glass 214. Simultaneously, the observation glass 214 ensured the sealing of the loading chamber 2, achieving visualized monitoring of the experimental process without affecting the sealing performance of the equipment and ensuring the stability of the experimental environment.

[0055] Further optimizing the design, monitoring component 4 includes a movable monitoring base 41 on the ground. A height-adjustable monitoring frame 42 is mounted on the monitoring base 41, and a monitoring head 43 is installed at the top of the monitoring frame 42. The monitoring head 43 monitors environmental data and deformation data of the test material 5 within the loading chamber 2 through an observation glass 214. The monitoring base 41 allows monitoring component 4 to be fixed to the ground, while the movement of the monitoring base 41 and the height adjustment of the monitoring frame 42 enable flexible adjustment of the monitoring head 43, allowing it to monitor through the observation glass 214, ensuring the accuracy and comprehensiveness of the monitoring and enhancing the equipment's ability to monitor the experimental process.

[0056] In one embodiment of the present invention, the monitoring head 43 is preferably a video extensometer. The video extensometer is a non-contact deformation measurement instrument based on optical imaging and digital image processing technology. Its core function is to accurately capture the displacement, strain and other mechanical deformation parameters of the material under test 5 during the stress process. It is widely used in the field of material mechanical property testing, and will not be described in detail here.

[0057] In one embodiment of the present invention, the monitoring component 4 further includes a plurality of monitoring sensors disposed in the loading chamber 2 for monitoring conditions such as temperature, humidity, pressure, and light in the loading chamber 2. Those skilled in the art can select appropriate monitoring sensors according to experimental requirements, which will not be elaborated here.

[0058] Further optimization of the design includes an environmental coupling component 3 comprising a heating head 31, a pressure regulating head 32, and a circulation fan 33 mounted on the loading chamber 2. The function of the environmental coupling component 3 is to provide a suitable environment for the experiment. This includes, but is not limited to, the heating head 31, the pressure regulating head 32, and the circulation fan 33. The heating head 31 regulates the temperature, the pressure regulating head 32 regulates the pressure, and the circulation fan 33 promotes environmental uniformity. Together, they couple different environmental conditions for the loading chamber 2, enabling a more comprehensive and accurate simulation of various environmental conditions and improving the realism of the experiment. Those skilled in the art can adjust the environmental parameters appropriately according to their needs; details will not be elaborated here.

[0059] This invention also discloses an experimental method for a large-scale, multifunctional experimental device with multi-field coupling transparency, comprising the following steps:

[0060] Open loading chamber 2, select the material to be tested 5 and place it into loading chamber 2, then install and fix it using the clamping assembly. When clamping the material to be tested 5, first disassemble the upper chamber 21 and the lower chamber 22. At this time, the material to be tested 5 can be placed stably in the corresponding position of the lower chamber 22. The lower chamber 22 has a specially designed placement area adapted to the shape and size of the material to be tested 5 to ensure the accuracy of material placement. Then, assemble the upper chamber 21 and the lower chamber 22. During the assembly process, ensure that the connector 28 of the upper chamber 21 is accurately inserted into the connector slot 27 of the lower chamber 22, so that the upper cooling chamber 26 and the lower cooling chamber 25 are connected to prevent the cooling medium from leaking. At the same time, achieve a sealed connection between the upper chamber 21 and the lower chamber 22 to prevent the loading chamber 2 from interacting with the external environment and ensure the independent environment in the loading chamber 2. The loading head at the end of the loading rod can be quickly and flexibly replaced according to experimental needs, and the loading method and clamping form can be flexibly adjusted according to different experimental needs, improving the versatility and flexibility of the equipment. Then, the clamping assembly clamps the test material 5 from multiple angles. The contact area between the clamping head 212 and the test material 5 is provided with anti-slip texture to enhance the stability of the clamping and prevent the material from sliding during loading.

[0061] Reassemble the loading box 2 and mount it on the frame 1. Secure the loading box 2 to the frame 1 using the fixing bracket 14. The loading box 2 is clamped and fixed to the frame 1 using the fixing bracket 14 that is movably mounted on the frame 1. The fixing bracket 14 has a certain degree of elasticity, which can reduce the rigid constraint on the loading box 2 while ensuring a firm fixation, thereby improving the flexibility and adaptability of the equipment.

[0062] Adjust the loading component so that its output end is connected to the clamping component, and test the stability of operation; the output end of the loading hydraulic cylinder 16 is connected to the clamping rod 210 through the quick connector 17. After the connection is completed, perform an operation stability test, start the loading component to perform a small range of loading action, observe the movement of the clamping component and the test material 5, and check for abnormal vibration, loosening or jamming, etc., to ensure the stability and reliability of the loading process;

[0063] The position of the monitoring component 4 is adjusted so that it can observe the parameters of the test material 5 in the loading chamber 2. The monitoring component 4 is fixed to the ground by the monitoring base 41, and the height of the monitoring frame 42 is adjusted to allow the monitoring head 43 to be flexibly adjusted in position, ensuring that the monitoring head 43 monitors through the observation glass 214. In addition, the monitoring component 4 also includes several monitoring sensors installed in the loading chamber 2 to monitor the temperature, humidity, pressure, light and other conditions in the loading chamber 2, which need to be calibrated before operation.

[0064] Activate the environmental coupling component 3 and adjust the environmental coupling parameters in the loading chamber 2 according to experimental requirements. Simultaneously, load the test material 5 and observe its changes under different environmental parameters. Adjust the environmental coupling parameters in the loading chamber 2 according to experimental requirements. For example, when it is necessary to adjust the temperature inside the loading chamber 2, especially when it is necessary to cool the environment inside the loading chamber 2, the cooling medium enters from the cooling inlet 23 into the lower cooling chamber 25, then flows into the upper cooling chamber 26, and finally flows out from the cooling outlet 24, with the medium entering from the lower end and exiting from the higher end. This cycle achieves temperature regulation of the loading chamber 2, improving temperature regulation efficiency and uniformity. At the same time, load the test material 5 and observe its changes under different environmental parameters, such as stress distribution, deformation, and damage development.

[0065] Record environmental coupling data and the data parameters of the material under test 5 to obtain the required experimental data. The environmental coupling data includes the change values ​​of parameters such as temperature, humidity, and pressure. The data parameters of the material under test 5 include mechanical parameters such as displacement, strain, and stress. These data are collected in real time by the monitoring component 4 and transmitted to the data recording system for storage and analysis to obtain the required experimental data.

[0066] After a set of experiments is completed, a new test material 5 can be quickly replaced, the environmental parameters can be readjusted, and loading and data recording can be performed to test data under different coupling environments. When replacing, the above steps of opening the loading box 2, loading the material, and fixing it should be repeated, and the environmental parameters should be readjusted. Loading and data recording should be performed again to test data under different coupling environments in order to comprehensively evaluate the performance of the material under different conditions.
