Description

Technical Field

[0001] This utility model relates to the field of environmental and vibration testing equipment, and specifically to a multi-purpose integrated testing system. Background Technology

[0002] In deep-sea oil and gas exploration and development, directional drilling equipment is a key piece of equipment, and its performance and reliability directly affect the safety and efficiency of exploration operations. However, the deep-sea environment is extremely complex and harsh, and the equipment must withstand the combined effects of various extreme factors such as high temperature, high pressure, high-intensity vibration, and corrosive media for extended periods during actual operations. High temperatures may originate from geothermal gradients or heat generated during equipment operation, while vibrations are often caused by mechanical motion, hydrodynamic impacts, and geological instability. These complex environmental factors can easily lead to material fatigue, structural deformation, seal failure, performance drift of electronic components, and even system malfunctions, severely impacting the working accuracy and service life of the directional drilling equipment.

[0003] Therefore, conducting high-temperature vibration tests to simulate extreme working conditions in actual deep-sea operations is of great significance for ensuring the reliable operation of directional drilling equipment. Through these tests, researchers can systematically study the dynamic response characteristics, performance evolution patterns, and failure mechanisms of equipment under combined high-temperature and vibration environments, identify design weaknesses and manufacturing defects, and clarify its adaptability boundaries in practical applications. The data obtained from these tests can not only provide a basis for optimizing and improving existing products but also provide direction and technical support for the development of next-generation high-performance directional drilling equipment, thereby promoting technological progress and innovation throughout the industry.

[0004] It is worth noting that due to significant differences in the structural dimensions of drilling rigs in practical applications, their lengths can range from several meters to tens of meters. Specimens of different lengths exhibit considerably different dynamic response characteristics under vibration excitation. Therefore, when conducting high-temperature vibration tests, it is essential to select an appropriate test method based on the specific structural form and dimensional characteristics of the specimen. For example, for shorter drilling rig components, a conventional single vibration test bench combined with a high-temperature environmental chamber can be used for individual high-temperature vibration tests. However, for ultra-long drilling rig systems, a dual-bench parallel-excitation vibration test system is required. By coordinating the phase and amplitude of the two vibration test benches, uniform excitation of the long specimen can be achieved, avoiding vibration transmission distortion and inconsistent response problems caused by excessive specimen length.

[0005] However, current high-temperature vibration comprehensive testing equipment on the market is still mainly composed of standard and general-purpose environmental simulation chambers, with relatively simple structural forms and functional configurations. Most products can only support a single vibration test bench excitation mode, or can only complete tests within a limited size range, lacking a systematic consideration of the testing needs of drilling equipment of different lengths. This technical bottleneck not only limits the effective conduct of full-scale testing of drilling equipment, but also restricts the standardization and accuracy improvement of related testing methods, further affecting the improvement of the independent research and development and quality assurance system for high-end deep-sea equipment.

[0006] In conclusion, developing a comprehensive high-temperature vibration testing system that can adapt to multiple testing modes and support drilling equipment of different sizes has become an urgent need for the development of testing technology for deep-sea oil and gas exploration equipment. Utility Model Content

[0007] The purpose of this invention is to provide a multi-purpose integrated testing system.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-purpose integrated testing system includes an environmental simulation chamber and at least one vibration test bench; The operating modes of the test system include vibration test mode, environmental test mode, and combined vibration and environmental test mode; The vibration test mode and the vibration and environment composite test mode include single-unit excitation vibration test and multi-unit parallel excitation vibration test.

[0010] A further technical solution is that the top of the environmental simulation chamber is provided with a specimen loading and unloading port, the length of which corresponds to the length of the specimen, and the specimen loading and unloading port is sealed by a sealing door panel.

[0011] A further technical solution also includes a specimen hoisting frame, which is suspended above the environmental simulation box and / or the vibration test bench; The specimen hoisting frame has multiple hoisting points arranged at intervals along the X-axis, which are used to hoist the specimen onto the vibration test bench or into the environmental simulation chamber via the specimen pick-up and drop-off port.

[0012] A further technical solution is that the vibration test bench is equipped with a thermal insulation support assembly for positioning and supporting the specimen; The bottom plate of the environmental simulation chamber has clearance holes corresponding to the thermal insulation support assembly, and the thermal insulation support assembly is sealed and thermally insulated from the bottom plate of the environmental simulation chamber.

[0013] A further technical solution is that, during multiple parallel vibration tests, the thermal insulation support assembly is provided in multiple sets, and is set one-to-one with the vibration test bench. Each of the thermal insulation support assemblies is arranged in a straight line in the X-axis direction for positioning support of the specimen. Each thermal insulation support assembly includes, in order from bottom to top, a ball bearing, a water-cooled adapter, a flexible thermal insulation structure, and a clamp for clamping the specimen; The ball bearing is fixed to the top of the moving ring of the platform. It also includes a thermal insulation cover, which is at least placed around the periphery of the ball bearing, and is sealed and fixed to the upper surface of the base plate below it, and is sealed and fitted with the flexible thermal insulation structure above it.

[0014] A further technical solution is that the thermal insulation support assembly includes a water-cooled adapter, a tooling fixture, a flexible thermal insulation structure, and at least one fixture for clamping the specimen, which are connected in sequence from bottom to top. The water-cooled adapter is fixed to the top of the moving ring of the platform. It also includes a heat insulation cover, which is installed around the tooling fixture, and is sealed and fixed to the upper surface of the base plate below, and is sealed and fitted with the flexible heat insulation structure above.

[0015] A further technical solution is that the thermal insulation support assembly includes a water-cooled adapter, an additional platform, and a flexible thermal insulation structure connected sequentially from bottom to top; The water-cooled adapter is fixed to the top of the moving ring of the platform. It also includes a heat insulation cover, which is installed around the water-cooled adapter, and is sealed and fixed to the upper surface of the base plate below it, and is sealed and fitted with the flexible heat insulation structure above it.

[0017] A further technical solution is that at least one of the vibration test benches is driven and its position is adjustable along the X-axis.

[0018] A further technical solution is that the flexible thermal insulation structure includes a thermal insulation board and a thermal insulation film positioned on the thermal insulation board.

[0019] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0020] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0021] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0022] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0023] The working principle and advantages of this utility model are as follows: 1. Multiple vibration test benches are arranged in a straight line along the X-axis, achieving full-size compatibility and efficient collaboration. The system arranges multiple vertical vibration test benches in a straight line along the X-axis. This layout allows the system to flexibly adapt to drilling equipment of different lengths: for short specimens, a single excitation unit is sufficient; for ultra-long specimens, multiple units can be used in parallel excitation mode, with the system collaboratively controlling each vibration test bench to output synchronized vertical vibration signals, jointly supporting and exciting the specimen, effectively simulating distributed vibration loads under real-world working conditions. This design fundamentally solves the problem of difficulty in conducting effective and accurate vibration testing due to differences in specimen size, providing a crucial platform for the reliability verification of full-size products.

[0024] 2. The Y-axis of the environmental simulation chamber is movable, significantly improving resource utilization and testing flexibility. The environmental simulation chamber is designed to move along the Y-axis, enabling high system flexibility and efficiency. During combined vertical vibration and environmental tests, the chamber can be moved to the working position, sealing the vibration test bench surface to form a large, enclosed environmental simulation chamber. When only a single vertical vibration test or an independent environmental test is required, the chamber can be moved to one side. This design allows different types of tests to be performed in parallel or quickly switched, avoiding the waiting time and repeated disassembly and reassembly of equipment in traditional serial testing processes, thus significantly shortening the overall testing cycle and improving the utilization of time and space resources.

[0025] 3. Precise integration of vibration and environment to realistically simulate extreme deep-sea conditions. The system can simulate combined environmental factors such as vibration and temperature (and humidity). In the combined testing mode, the system can precisely control the temperature (and humidity) within the environmental simulation chamber while simultaneously superimposing vibration stresses, such as those in the vertical direction. Therefore, it can highly reproduce the extreme working conditions of the deep-sea environment under the combined effects of high temperature / high humidity and mechanical vibration, helping to expose potential defects and coupled failure modes (e.g., fatigue failure of materials under the combined effects of thermal expansion and contraction and continuous vertical vibration) that cannot be detected by single stress testing. This provides extremely realistic and accurate experimental data for the technical improvement of drilling equipment.

[0026] 4. Modular and highly reliable design ensures long-term stable operation of the system. The system adopts a modular design, with clearly defined functions and interfaces for core components such as the vibration test bench and the movable environmental simulation chamber. This facilitates daily maintenance and allows for future functional expansion. Meanwhile, the system's key structures utilize robust and durable designs and components, ensuring stability and reliability under long-term, high-intensity, and complex environmental testing, thus reducing equipment failure rates and overall lifecycle maintenance costs.

[0027] In summary, this invention, by simultaneously applying environmental simulation and multiple coordinated vibrations, can realistically reproduce extreme working conditions in the deep sea, such as the coupling of high temperature and vibration. It can uncover potential failure modes that cannot be revealed by a single stress test, such as fatigue failure of materials under the combined effects of thermal expansion and contraction and mechanical vibration. By arranging multiple vibration test benches coaxially along the X-axis and coordinating their control, uniform and distributed excitation of long specimens is achieved, resulting in a load distribution that more closely resembles reality. This avoids localized overload or insufficient excitation, making the overall response of the specimen more realistic and the test results more valuable for reference. The integrated design supports rapid switching between test modes; the movable environmental simulation chamber allows for parallel environmental simulation and vibration testing, significantly saving time and space. This shortens the test cycle, reduces labor and equipment costs, and minimizes errors and risks introduced by multiple clamping operations. In summary, the movable environmental chamber and modular multi-unit vibration test bench layout of this invention enable the system to flexibly adapt to testing needs ranging from short to ultra-long specimens. A single system solves the testing challenges of specimens of various sizes, improving equipment and site utilization and expanding its application scope.

[0028] Through further technical solutions, this utility model can also bring about the following superior technical effects: 1) This utility model allows for the installation of partitions within the environmental simulation chamber, dividing the chamber into independent sub-chambers. This design enables: It can significantly improve testing efficiency, enabling the parallel execution of various environmental-vibration combination tests and greatly shortening the test cycle; it can optimize resources and energy consumption, sharing core environmental simulation systems (such as cooling / heating units) to reduce equipment costs and operating energy consumption; it can enhance space utilization, achieving "one box for multiple uses"; it can ensure the independence and precision of the test chamber, with independent control of environmental parameters in each sub-chamber to avoid mutual interference and ensure the purity of test conditions and the accuracy of results; it can improve system flexibility and scalability, with modular partition design that allows for easy adjustment of the number and layout of chambers according to needs, adapting to future changes in testing requirements.

[0029] 2) This utility model allows for the creation of a specimen loading / unloading port at the top of the environmental simulation chamber. A specimen lifting rack is then used to directly lower long specimens into the chamber from the top, ensuring a high level of airtightness when the loading / unloading port is closed. This design achieves the following: By utilizing vertical space, specimens are directly hoisted in from above, with a direct trajectory, simplifying the positioning and alignment process, making the operation faster and safer; the clamping process is modularized, allowing specimens to be positioned on the hoisting frame outside the chamber before being quickly hoisted into the environmental simulation chamber, shortening the test preparation cycle; the use of specialized hoisting equipment enables controllable and stable transfer and placement, significantly reducing the risk of specimen damage; The flexible design of the hoisting frame can easily accommodate specimens of different lengths. Precise vertical positioning helps ensure the consistency of the connection between the specimen and the vibration test bench, improving the accuracy of test results and the repeatability of the test.

[0030] 3) This utility model can be equipped with a thermal insulation support assembly for positioning and supporting the test specimen on the vibration test bench. On the one hand, it supports the test specimen, and on the other hand, it isolates the environment inside the environmental simulation chamber, avoiding adverse effects of environmental factors on the vibration test bench.

[0031] The thermal insulation support assembly includes a water-cooled adapter, a flexible thermal insulation structure, and a thermal insulation cover. Through the combined design of these three components, it achieves the following unique technical effects under combined vibration and environmental testing modes: First, the thermal insulation cover directly faces the test temperature (especially extreme temperatures) inside the environmental simulation chamber, and through its thermal insulation properties, it blocks most of the heat from the outside, significantly reducing the temperature load transferred to the supporting structure below.

[0032] Then, the water-cooled adapter handles the residual heat from breaking through the insulation cover and the heat generated by the vibration table itself. It actively removes heat via external circulating water, ensuring that the moving coil of the vibration table remains within a safe temperature range. This not only prevents equipment damage due to overheating but also ensures that the temperature field within the environmental simulation chamber is not affected by the table's temperature, thereby improving the accuracy of the test data.

[0033] Finally, the flexible thermal insulation structure, as a key component connecting the two, not only achieves a reliable seal at the bottom of the environmental simulation chamber, ensuring the stability of the temperature and humidity environment, but its flexibility also ensures that the mechanical vibrations generated by the vibration table can be transmitted to the specimen with almost no loss. It perfectly balances the contradiction between "static sealing" and "dynamic vibration," which is a prerequisite for the effective operation of the other two components.

[0034] In summary, the design of the thermal insulation support component brings the following synergistic value: Comprehensive protection: From isolating the high-temperature source to heat dissipation through the conduction path, and then to temperature control of core components, a multi-layered and three-dimensional temperature protection system has been formed.

[0035] Ensuring test accuracy: It not only protects the equipment but also ensures the purity of vibration excitation and the stability of the temperature field, laying a solid foundation for obtaining real and reliable test data.

[0036] Improved system reliability: Through division of labor and cooperation, the adverse effects of high-temperature environment on precision vibration table are minimized, greatly enhancing the robustness and service life of the entire composite test system. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0040] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0041] See appendix Figures 1-3 As shown, this embodiment discloses a multi-purpose integrated testing system, including a horizontal base 1, an environmental simulation chamber 2 and two vibration test benches 3 set on the horizontal base 1.

[0042] The operating modes of this test system include vibration test mode (vibration only), environmental test mode (environment only), and combined vibration and environmental test mode. Among them, the vibration test in the vibration test mode and the combined vibration and environmental test mode includes single-unit (vibration test bench 3) excitation vibration test and multi-unit (vibration test bench 3) parallel excitation vibration test (in this embodiment, it is a dual-unit test bench).

[0043] During multiple parallel vibration tests, the moving coils 31 of each vibration test bench 3 are arranged in a straight line along an X-axis.

[0044] In the combined vibration and environmental test mode, the environmental simulation chamber 2 is sealed on the moving coil 31 of the vibration test bench 3, forming a closed environmental simulation cavity 21; in the parallel vibration test of multiple benches, the length of the environmental simulation cavity 21 is greater than the length of the specimen 4 simultaneously positioned on the moving coil 31 of each vibration test bench 3.

[0045] The environmental simulation box 2 is movable along a Y-axis direction via a first guide rail 11 (or a ceiling rail). Figure 4 As shown, in the vibration test mode, the environmental simulation chamber 2 is moved to one side of the Y-axis direction of each of the vibration test benches 3. Figure 5 As shown, the environmental simulation chamber 2 can also be moved to one side of the Y-axis direction of each of the vibration test benches 3 in the environmental test mode, and the specimen 4 is positioned by the specimen hoisting frame 5. In the environmental test mode (environment only), the environmental simulation chamber 2 can also remain combined with the vibration test bench 3, using the vibration test bench as the platform for the specimen 4.

[0046] Preferred, such as Figures 6-8 As shown, the top of the environmental simulation chamber 2 has a specimen loading / unloading port 23, the length of which corresponds to the length of the specimen 4, and the specimen loading / unloading port 23 is sealed by a sealing door plate 24. The sealing door plates 24 are arranged in pairs, and a sealing element 25 (such as silicone rubber) is provided at the joint to ensure that the sealing door plate 24 effectively seals the specimen loading / unloading port 23 when closed, thereby ensuring the airtightness of the environmental simulation chamber 21.

[0047] Preferred, such as Figure 2As shown, it also includes a specimen hoisting frame 5, which is suspended from the top of the environmental simulation chamber 2 and / or the vibration test bench 3. The specimen hoisting frame 5 has multiple hoisting points 51 arranged at intervals along the X-axis, which are used to hoist the specimen 4 into the environmental simulation chamber 2 or onto the vibration test bench 3 via the specimen loading and unloading port 23 through the hoisting rope 52.

[0048] During the parallel vibration test of multiple units, the suspension rope 52 does not detach from the specimen 4. In the composite test mode, the suspension rope 52 passes through the joint between the sealing door panels 24, such as... Figure 9 As shown, a seal is achieved by sealing element 25, thereby keeping the top of the environmental simulation chamber 2 sealed.

[0049] Preferred, such as Figure 10 , Figure 11 As shown, a partition 22 is vertically installed in the environmental simulation chamber 2. By setting the horizontal position of the partition 22 within the environmental simulation chamber 2, the environmental simulation cavity 21 is divided into two isolated sub-chambers 211. Each sub-chamber 211 can be used for environmental simulation tests independently, or each sub-chamber 211 can be used for combined vibration and environmental tests independently. This "compartmental" design improves the utilization rate of the environmental simulation cavity 21 per unit time.

[0050] Preferred, such as Figure 14 As shown, the vibration test bench 3 is equipped with a thermal insulation support assembly 6 for positioning and supporting the specimen 4. The bottom plate 26 of the environmental simulation chamber 2 has a circular clearance hole 27a corresponding to the thermal insulation support assembly, or it is equipped with a detachable movable plate 29 with a circular clearance hole 27a. The thermal insulation support assembly 6 and the circular clearance hole 27a of the environmental simulation chamber 2 are sealed and thermally insulated together.

[0051] The movable plate 29 is made of a pressure-bearing plate with an insulation layer, possessing heat insulation, pressure resistance, and load-bearing capacity. The diameter of the circular clearance hole 27a can be flexibly configured according to requirements. Figure 12 The diagram shown is a schematic of the movable plate 29.

[0052] The bottom of the environmental simulation chamber 2 is provided with a rectangular clearance hole 27b. The rectangular clearance hole 27b is configured to have a length, and the length direction corresponds to the length direction of the chamber body, so as to adapt to the combination requirements of the bottom of different sub-chambers 211 and different vibration test benches 3. More importantly, the rectangular clearance hole 27b can realize the specimen clamping and positioning requirements after the vibration test bench 3 is moved horizontally on one side.

[0053] like Figure 13 As shown, it also includes at least one sealing plate 28, which is spliced ​​and combined with the movable plate 29 to jointly seal the rectangular clearance hole 27b, so as to achieve the sealing of the environmental simulation box 2.

[0054] like Figures 14-16 As shown, in one embodiment, during multiple parallel vibration tests, the thermal insulation support assembly 6 is provided in multiple sets and is set one-to-one with the vibration test bench 3. Each of the thermal insulation support assemblies 6 is arranged in a straight line in the X-axis direction for positioning support of the specimen 4 (long specimen).

Figure 17 ), Conical water-cooled adapter 62a (see Figure 18 ), flexible thermal insulation structure 63 and clamp 64 (see) Figure 19 ), used to clamp rod-shaped specimen 4.

[0056] The ball bearing 61 is fixed to the moving ring 31 of the test bench and is used for mechanical decoupling when multiple (dual) vibration test benches are tested in parallel.

[0057] Also includes the 65a ball-head thermal insulation cover (see Figure 20 The ball head insulation cover 65a is installed around the conical water-cooled adapter 62a and the ball head bearing 61, and is sealed and fixed to the upper surface of the base plate 26 below, and is sealed and fitted with the flexible thermal insulation structure 63 above. The ball head insulation cover 65a is used to isolate the temperature (such as high temperature) in the environmental simulation chamber 2 to avoid adverse effects on the ball head bearing 61.

[0058] The flexible thermal insulation structure 63 includes a thermal insulation plate 631 and a thermal insulation film 632 positioned on the thermal insulation plate 631. Figure 15 , Figure 16 As shown, the insulation plate 631 is fixed to the top of the conical water-cooled adapter 62a, and the outer edge of the insulation film 632 is positioned at the upper part of the ball-shaped insulation cover 65a. This design can achieve both thermal insulation and sealing of the gap between the insulation plate 631 and the ball-shaped insulation cover 65a, and flexible connection between the insulation plate 631 and the ball-shaped insulation cover 65a.

[0059] like Figures 21-23 As shown, in another embodiment, the thermal insulation support assembly 6 includes cylindrical water-cooled adapters 62b connected sequentially from bottom to top (see...). Figure 24 ), tooling fixtures 60 (see) Figure 25 Its length corresponds to the length of specimen 4), flexible thermal insulation structure 63, and multiple clamps 64 (see Figure 19 In this embodiment, each clamp 64 is equidistantly spaced along the length of the tooling fixture 60 to clamp the specimen 4 of a certain length.

[0060] The cylindrical water-cooled adapter 62b is fixed to the moving coil 31 of the platform.

[0061] Also includes clamp insulation cover 65b (see Figure 26 The heat insulation cover 65b is installed around the tooling fixture 60, and is sealed and fixed to the upper surface of the base plate 26 below. It is sealed and fitted with the flexible heat insulation structure 63 above. The heat insulation cover 65b is used to isolate the temperature (such as high temperature) in the environmental simulation chamber 2 to avoid adverse effects on the tooling fixture 60.

[0062] The flexible thermal insulation structure 63 includes a thermal insulation plate 631 and a thermal insulation film 632 positioned on the thermal insulation plate 631. Figure 22 , Figure 23 As shown, the insulation plate 631 is fixed to the top of the tooling fixture 60, and the outer edge of the insulation film 632 is positioned on the upper part of the fixture insulation cover 65b. This design can achieve both thermal insulation and sealing of the gap between the insulation plate 631 and the fixture insulation cover 65b, and flexible connection between the insulation plate 631 and the fixture insulation cover 65b.

[0063] like Figures 27-29 As shown, in another embodiment, the thermal insulation support assembly 6 includes cylindrical water-cooled adapters 62b connected sequentially from bottom to top (see...). Figure 24 Additional countertop 66 (see) Figure 30 The additional platform 66 is used to place the small specimen 4.

[0064] The cylindrical water-cooled adapter 62b is fixed to the moving coil 31 of the platform.

[0065] Also includes a 65°C countertop heat shield (see Figure 31 The additional platform 65c is installed around the periphery of the additional platform 66, and is sealed and fixed to the upper surface of the base plate 26 below, and is sealed and fitted with the flexible thermal insulation structure 63 above. The platform thermal insulation cover 65c is used to isolate the temperature (such as high temperature) in the environmental simulation chamber 2 to avoid adverse effects on the additional platform 66.

[0066] The flexible thermal insulation structure 63 includes a thermal insulation plate 631 and a thermal insulation film 632 positioned on the thermal insulation plate 631. Figure 28 , Figure 29 As shown, the insulation plate 631 is fixed to the top of the additional tabletop 66, and the outer edge of the insulation film 632 is positioned on the upper part of the tabletop insulation cover 65c. This design can achieve both thermal insulation and sealing of the gap between the insulation plate 631 and the tabletop insulation cover 65c, and flexible connection between the insulation plate 631 and the tabletop insulation cover 65c.

[0067] Preferably, in the above embodiments, the heat insulation film 632 can be made of heat-resistant silicone rubber, which is a prior art material and will not be described in detail here.

[0068] Preferably, in the above embodiments, the water-cooled adapter has an inlet and an outlet on its side, and has a water flow channel inside for cooling the water-cooled adapter (not shown in the figure).

[0069] Preferably, the side of the tapered water-cooling adapter 62a can be provided with multiple heat dissipation fins to increase the heat dissipation area of ​​air cooling, and the superimposed water cooling can further ensure the heat dissipation effect.

[0070] In practice, the temperature and flow rate of the circulating water can be adjusted according to design requirements or the real-time detected temperature at the bottom of the water-cooled adapter. During operation, the water-cooled adapter is connected to external circulating water. Both the temperature inside the upper environmental simulation chamber 21 and the temperature of the moving coil 31 of the lower vibration test bench 3 can be carried away by the external circulating water through the water-cooled adapter. This prevents temperature transfer to the moving coil 31 during high-temperature testing, thus avoiding overheating of the vibration test bench 3 and potential malfunctions or damage. It also ensures that the temperature inside the environmental simulation chamber 21 is not affected by the temperature of the moving coil 31.

[0071] The water-cooling adapter can be configured to be wider at the top and narrower at the bottom (see...). Figure 18 (See Embodiment 1) or equal width at the top and bottom (see Figure 24 Specifications such as those in Embodiment 2 and Embodiment 3 are used to ensure effective support for specimen 4.

[0072] Preferred, such as Figure 32 As shown, at least one of the vibration test benches 3 is driven and its position is adjustable along the X-axis via the second guide rail 12. This design is intended to accommodate the requirements of parallel vibration tests on specimens 4 of different lengths.

[0073] In implementation, the movable vibration test bench 3 is positioned corresponding to the rectangular clearance hole 27b. After each adjustment of the horizontal position of the vibration test bench in the X-axis direction, the movable plate 29 is moved within the rectangular clearance hole 27b, allowing the thermal insulation support assembly 6 on the vibration test bench 3 to align vertically with the circular clearance hole 27a of the movable plate 29. Simultaneously, one or more sealing plates 28 seal the rectangular clearance hole 27b. This design enables the test chamber to have flexible compatibility when clamping specimens of different lengths for parallel vibration testing, thereby effectively improving the system's versatility.

[0074] Preferably, a heating device (such as a heating wire) can be directly installed inside the environmental simulation chamber 2 of this invention. Since the heating device is relatively conventional and its placement is not particularly important, it is not shown in the diagram of the chamber. Furthermore, in addition to high-temperature testing, this invention can also simulate other environmental tests such as low-temperature and humidity tests by setting up other corresponding equipment; therefore, this invention is not limited to the type of environmental test. Figure 33 , Figure 34 As shown, in this embodiment, an equipment placement room 7 is provided on one side of the insulated box 20. The equipment placement room 7 is equipped with a refrigeration unit 71 and a humidity device 72, thereby providing low temperature simulation or humidity simulation for the environmental simulation chamber 21 inside the insulated box 20.

[0075] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
