Description

Technical Field

[0001] This utility model relates to the field of vibration testing equipment, and in particular to a multi-mode vibration testing device. Background Technology

[0002] During operation, new energy vehicles are subjected to vibration loads of varying frequencies and amplitudes due to factors such as road bumps or collisions. Specifically, the chips, electronic components, vehicle systems, and electrical components contained in the vehicle are more sensitive to high-frequency vibrations, typically requiring electromagnetic vibration tables to simulate vibration environments ranging from hundreds to thousands of hertz. Components such as battery packs, car seats, wiring harnesses, and lights are more susceptible to low-frequency, large-displacement vibrations, which often require the use of hydraulic vibration tables for reproduction. The frequency range is generally below 1 Hz to tens of hertz, with displacements reaching 200 mm to 300 mm.

[0003] Currently, when undertaking vibration testing services, testing organizations often need to cover a wide range of vibration conditions, from low-frequency large displacement to high-frequency vibration. Electromagnetic vibration tables typically feature light loads, a wide frequency range, and small displacements; while hydraulic vibration tables are suitable for vibration environments with large loads, low frequencies, and large displacements.

[0004] In practical applications, if the product under test has a complex structure containing multiple components, and each component corresponds to different frequencies of vibration excitation under actual working conditions, a single type of vibration table is often insufficient to fully meet the test requirements. Currently, the common solution is to configure both electromagnetic and hydraulic vibration table systems simultaneously. However, this approach involves high equipment investment costs, large space requirements, and high complexity in use and maintenance. Therefore, there is an urgent need for a composite vibration test solution that can integrate high and low frequency vibration excitation and cover a wide frequency band and a large displacement range.

[0005] In view of this, it is necessary to improve the existing vibration testing equipment to solve the above problems. Utility Model Content

The second flipping component is connected to the electromagnetic vibration table to drive the electromagnetic vibration table to rotate. The multi-mode vibration test device has a fifth mode in which the electromagnetic vibration table is connected to the electromagnetic vertical vibration table surface to drive the electromagnetic vertical vibration table surface to vibrate in the vertical direction.

Detailed Implementation

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1 to 8 As shown, the multi-mode vibration testing device 100 of this utility model includes a slide table component 1, a horizontal platform surface 2 disposed on the slide table component 1 and slidable along the slide table component 1, a hydraulic vibration table 3 located at one end of the horizontal platform surface 2 along the sliding direction of the horizontal platform surface 2, and an electromagnetic vibration table 4 located at the other end of the horizontal platform surface 2 along the sliding direction of the horizontal platform surface 2.

[0022] The slide plate component 1 is provided with multiple slide rails and a slider that can slide relative to the slide rails. The horizontal platform surface 2 is fixedly connected to the slider and is slidably arranged relative to the guide rail.

[0023] The vibration frequency of the hydraulic vibration table 3 is between 0.1Hz and 200Hz, which is defined as low frequency. The vibration displacement is far greater than 100mm, and the displacement exceeding 100mm is defined as large displacement. The vibration frequency of the electromagnetic vibration table 4 is between 2Hz and 2000Hz, and the frequency above 200Hz is defined as high frequency. The vibration displacement is within 100mm.

[0024] The hydraulic vibration table 3 and the electromagnetic vibration table 4 are respectively located at opposite ends of the horizontal platform 2.

[0025] The multi-mode vibration testing device 100 has a first mode in which the hydraulic vibration table 3 is connected to the horizontal platform 2, a second mode in which the electromagnetic vibration table 4 is connected to the horizontal platform 2, and a third mode in which the hydraulic vibration table 3 and the electromagnetic vibration table 4 are simultaneously connected to the horizontal platform 2.

[0026] like Figure 2 As shown, when the multi-mode vibration test device 100 is in the first mode, only the hydraulic vibration table 3 is connected to the horizontal platform 2, while the electromagnetic vibration table 4 is connected to the horizontal platform 2. The first mode is suitable for the test piece to be subjected to ultra-low frequency excitation in the horizontal direction. The hydraulic vibration table 3 is connected to the horizontal platform 2 in the horizontal direction, which can realize the test requirements of low frequency large displacement vibration.

[0027] like Figure 3 As shown, when the multi-mode vibration testing device 100 is in the second mode, only the electromagnetic vibration table 4 is connected to the horizontal platform 2, while the hydraulic vibration table 3 is also connected to the horizontal platform 2. This second mode is suitable for situations where the test piece requires high-frequency excitation in a horizontal direction. The electromagnetic vibration table 4 is connected to the horizontal platform 2 in a horizontal direction, thus fulfilling the testing requirements for high-frequency vibration. It should be noted that if the vibration test does not require large displacements, low-frequency tests can also be performed when the multi-mode vibration testing device 100 is in the second mode.

[0028] like Figure 4 As shown, when the multi-mode vibration test device 100 is in the third mode, the hydraulic vibration table 3 and the electromagnetic vibration table 4 are simultaneously connected to the horizontal platform 2. The third mode is suitable for the test piece when it is subjected to mid-frequency excitation in the horizontal direction. Mid-frequency refers to 2 to 200 Hz. The electromagnetic vibration table 4 and the electro-hydraulic vibration table can simultaneously meet the vibration requirements of this frequency. The third mode can realize the superposition of the thrust of the electromagnetic vibration table 4 and the hydraulic vibration table 3, and can realize a larger scale of vibration test.

[0029] The multi-mode vibration testing device 100 of this invention, by setting up a hydraulic vibration table 3 and an electromagnetic vibration table 4 that can be selectively connected to the horizontal platform 2, allows for the selection of the appropriate vibration table according to the frequency range of the test conditions, and can also be used simultaneously to conduct a large number of vibration tests. This multi-mode vibration testing device 100 integrates electromagnetic and hydraulic systems, has multiple operating modes, is suitable for different vibration tests, has low investment cost, occupies little space, is simple to use and maintain, and can integrate high and low frequency vibration excitation, covering a wide frequency band and a large displacement range for composite vibration tests.

[0030] like Figures 1 to 4 As shown, in order to connect the horizontal platform 2 and the hydraulic vibration table 3, in this embodiment, the multi-mode vibration testing device 100 further includes a hydraulic connector 5. When the multi-mode vibration testing device 100 is in the first mode and the third mode, the hydraulic connector 5 connects the hydraulic vibration table 3 and the horizontal platform 2. In other embodiments, the hydraulic connector 5 may also be part of the hydraulic vibration table 3.

[0031] To connect the horizontal platform 2 and the electromagnetic vibration table 4, in this embodiment, the multi-mode vibration testing device 100 further includes an electromagnetic connector 6. When the multi-mode vibration testing device 100 is in the second and third modes, the electromagnetic connector 6 connects the electromagnetic vibration table 4 and the horizontal platform 2. In other embodiments, the electromagnetic connector 6 may also be part of the electromagnetic vibration table 4.

[0032] The hydraulic connector 5 and the electromagnetic connector 6 can be fixed to the horizontal platform 2 by means of bolt connection, quick clamp or other connection methods.

[0033] like Figure 5 As shown, to achieve more modes of functionality, in this embodiment, the multi-mode vibration testing device 100 further includes a first tilting component 7 connected to the hydraulic vibration table 3 and a hydraulic vertical vibration table 8. The first tilting component 7 is connected to the hydraulic vibration table 3 to drive the hydraulic vibration table 3 to rotate. The multi-mode vibration testing device 100 has a fourth mode in which the hydraulic vibration table 3 is connected to the hydraulic vertical vibration table 8 to drive the hydraulic vertical vibration table 8 to vibrate in the vertical direction. In the fourth mode, the hydraulic vibration table 3 can drive the hydraulic vertical vibration table 8 to vibrate in the vertical direction, thereby enabling low-frequency, large-displacement vertical vibration testing.

[0034] The first tilting assembly 7 can tilt the hydraulic vibration table 3 by 90 degrees, allowing the hydraulic vibration table 3 to output vibration excitation in the vertical direction. The first tilting assembly 7 includes a motor and a transmission component to drive the hydraulic vibration table 3 to rotate. However, in other embodiments, the first tilting assembly 7 can also rotate the hydraulic vibration table 3 by more than 90 degrees to achieve vibration tests at more angles.

[0035] like Figures 1 to 7 As shown, the multi-mode vibration test device 100 also includes a base 9, on which a first flip trunnion seat 91 is provided, and on which a hydraulic flip trunnion 31 is provided on the hydraulic vibration table 3. The hydraulic flip trunnion 31 is rotatably disposed relative to the first flip trunnion seat 91. When the first flip component 7 drives the hydraulic vibration table 3 to rotate, the hydraulic flip trunnion 31 rotates relative to the first flip trunnion seat 91.

[0036] like Figure 5 As shown, to achieve more modes of functionality, in this embodiment, the multi-mode vibration testing device 100 further includes a second flipping assembly 10 connected to the electromagnetic vibration table 4 and an electromagnetic vertical vibration table 11. The second flipping assembly 10 is connected to the electromagnetic vibration table 4 to drive the electromagnetic vibration table 4 to rotate. The multi-mode vibration testing device 100 has a fifth mode in which the electromagnetic vibration table 4 is connected to the electromagnetic vertical vibration table 11 to drive the electromagnetic vertical vibration table 11 to vibrate in the vertical direction. In the fifth mode, the electromagnetic vibration table 4 can drive the electromagnetic vertical vibration table 11 to vibrate in the vertical direction, thereby enabling high-frequency vertical vibration testing.

[0037] The second flipping assembly 10 can flip the electromagnetic vibration table 4 by 90 degrees, allowing the electromagnetic vibration table 4 to output vibration excitation in the vertical direction. The second flipping assembly 10 includes a motor and a transmission component to drive the electromagnetic vibration table 4 to rotate. However, in other embodiments, the second flipping assembly 10 can also drive the electromagnetic vibration table 4 to rotate by more than 90 degrees to achieve vibration tests at more angles.

[0038] The base 9 is provided with a second flip trunnion seat 92, and the electromagnetic vibration table 4 is provided with an electromagnetic flip trunnion 41. The electromagnetic flip trunnion 41 is rotatably arranged relative to the second flip trunnion seat 92. When the second flip assembly 10 drives the electromagnetic vibration table 4 to rotate, the electromagnetic flip trunnion 41 rotates relative to the second flip trunnion seat 92.

[0039] When the test piece is in a vertical position, the electromagnetic vibration table 4 or hydraulic vibration table 3 can be flipped to a vertical position according to the test type, and then the corresponding electromagnetic vertical vibration table surface 11 or hydraulic vertical vibration table surface 8 can be connected. Of course, in some embodiments, the multi-mode vibration test device 100 can be connected to the corresponding electromagnetic vertical vibration table surface 11 or hydraulic vertical vibration table surface 8 simultaneously.

[0040] Referring to the third mode of the multi-mode vibration testing device 100, if a larger-scale vertical vibration test at medium frequencies is required, the multi-mode vibration testing device 100 also includes a first tilting assembly 7 connected to the hydraulic vibration table 3, a second tilting assembly 10 connected to the electromagnetic vibration table 4, and a large-scale vertical vibration table surface connected to both the hydraulic vibration table 3 and the electromagnetic vibration table 4. The multi-mode vibration testing device 100 also has a sixth mode in which the electromagnetic vibration table 4 and the hydraulic vibration table 3 are simultaneously connected to the large-scale vertical vibration table surface to drive the large-scale vertical vibration table surface to vibrate in the vertical direction.

[0041] The multi-mode vibration testing device 100 of this utility model can not only realize horizontal vibration at different frequencies, but also realize vertical vibration tests at different frequencies.

[0042] To achieve automated control, the multi-mode vibration test device 100 also includes a control unit, which is electrically connected to the hydraulic vibration table 3 and the electromagnetic vibration table 4, thereby enabling the hydraulic vibration table 3 and the electromagnetic vibration table 4 to work independently or in concert. Of course, in some embodiments, the control unit is also electrically connected to the first flipping component 7 and the second flipping component 10, etc.

[0043] The hydraulic vibration table 3 and the electromagnetic vibration table 4 are selectively connected to the horizontal platform 2, the hydraulic vertical vibration table 8, the electromagnetic vertical vibration table 11, or a large number of vertical vibration tables. The connection can be performed by workers or by automated equipment.

[0044] The multi-mode vibration testing device 100 of this utility model integrates electromagnetic and hydraulic systems, has multiple working modes, is suitable for different vibration tests, has low investment cost, occupies little space, is simple to use and maintain, and can integrate high and low frequency vibration excitation and composite vibration tests covering a wide frequency band and a large displacement range.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
