Description

Technical Field

[0001] This application relates to the field of acoustic testing technology, and more specifically, to an acoustic testing model and acoustic testing system for conformally attached acoustic materials. Background Technology

[0002] Acoustic testing of underwater acoustic materials primarily examines their acoustic properties, including sound absorption, reflection, and transmission. These tests aim to evaluate the acoustic characteristics of acoustic materials in underwater environments, providing a basis for the design of underwater engineering and equipment.

[0003] Currently, acoustic testing often involves simulating a scenario using a water tank. First, an acoustic test model without any acoustic material is placed in the water tank for testing. After the test, the model is removed, and the acoustic material to be tested is attached to it. Then, the model with the material attached is placed back into the water tank for another acoustic test. The results of the two tests are compared to obtain the acoustic performance of the material.

[0004] The testing process involves repeatedly taking out and putting in the acoustic test model, making the operation cumbersome and inefficient.

[0005] Therefore, a new technical solution is needed to address the technical problem of low testing efficiency of acoustic materials in acoustic testing. Utility Model Content

[0006] One objective of this application is to provide a new technical solution for an acoustic testing model of conformally attached acoustic materials.

[0007] According to a first aspect of this application, an acoustic test model for conformally attached acoustic materials is provided. The acoustic test model for conformally attached acoustic materials includes a sealing assembly; the sealing assembly includes multiple housings connected sequentially and enclosing a sealed cavity, at least one of the housings having acoustic material disposed on its outer wall; during acoustic testing, the sealing assembly is connected to a driving device, which drives the sealing assembly to rotate about its own axis.

[0008] Optionally, the housing has an arcuate sidewall, and the acoustic material has an attachment surface that conforms to the arcuate sidewall, the attachment surface being conformally attached to the arcuate sidewall.

[0009] Optionally, the projection of the arcuate sidewall onto a plane perpendicular to its axis is a minor arc.

[0010] Optionally, a support assembly is provided inside the sealing cavity, and multiple support assemblies are arranged along the axial direction of the sealing cavity.

[0011] Optionally, the acoustic test model of the conformally attached acoustic material further includes an adjustment component, which is disposed on the sealing component and connected to a driving device. The driving device drives the adjustment component to rotate about the axis of the sealing component.

[0012] Optionally, the sealing assembly has a first end and a second end disposed opposite to each other, and the adjusting assembly is disposed at the first end; wherein, the adjusting assembly includes an adjusting member, the adjusting member having an adjusting hole, and a plurality of the adjusting holes are distributed in a circular array with the axis of the sealing assembly as the array center.

[0013] Optionally, the adjustment hole extends from the arcuate sidewall toward the axis of the sealing assembly.

[0014] Optionally, the adjustment assembly includes two lifting rings arranged radially along the sealing cavity and located at opposite ends of the adjustment member.

[0015] According to a second aspect of this application, an acoustic testing system is provided, the acoustic testing system comprising a tank and an acoustic test model with conformally attached acoustic material as described above, wherein the acoustic test model with conformally attached acoustic material is located inside the tank during acoustic testing.

[0016] Optionally, the acoustic testing system further includes a driving device connected to the sealing assembly.

[0017] In this embodiment, by arranging acoustic material on the sidewalls of one or more housings of the sealing assembly, the acoustic test model simultaneously has sidewalls with and without acoustic material. During the acoustic test, the sealing assembly is driven to rotate by a driving device, causing the positions of the housings with and without acoustic material to change.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] According to one embodiment of this application, an acoustic test model for conformally attached acoustic material is provided. The acoustic test model for conformally attached acoustic material includes a sealing component 1. The sealing component 1 includes a plurality of housings 11, which are sequentially connected and enclosed to form a sealing cavity 12. At least one of the housings 11 has an acoustic material 2 disposed on its outer wall. During the acoustic test, the sealing component 1 is connected to a driving device, which drives the sealing component 1 to rotate around its own axis.

[0035] like Figures 1 to 5 As shown, this device is used to test the acoustic performance of acoustic material 2. The acoustic test is conducted by placing the device in a tank that simulates an acoustic environment.

[0036] The sealing assembly 1 is prismatic in shape, and acoustic material 2 is attached to at least one outer wall of the sealing assembly 1. Of course, acoustic materials 2 of different materials, thicknesses, or sizes can also be attached to multiple outer walls of the sealing assembly 1. The sealing assembly 1 is rotated by a driving device to test the acoustic performance of acoustic materials 2 of different materials, thicknesses, or sizes.

[0037] The acoustic test model of the conformally attached acoustic material includes a sealing assembly 1, which comprises multiple housings 11. The multiple housings 11 are integrally formed.

[0038] Of course, the sealing assembly 1 in this embodiment is not limited to the structure described above, and those skilled in the art can configure it according to actual needs. For example, multiple housings 11 can also be spliced ​​together to form the sealing assembly 1.

[0039] like Figures 1 to 5 As shown, the housing 11 is a steel structure, and the sidewalls of the housing 11 are arc-shaped. The housing 11 is connected to form an elliptical cylindrical acoustic test model. By setting the acoustic test model to an elliptical cylindrical shape, the pressure resistance of the acoustic test model during the acoustic testing process can be effectively improved.

[0040] The acoustic material 2 to be tested is set on the outside of the housing 11. The elliptical cylindrical acoustic test model is set with acoustic material 2 on one side and no acoustic material 2 on the other side. The acoustic test model is immersed in a water tank for acoustic testing. The test data of the two states with and without acoustic material 2 can be detected by simply rotating the acoustic test model. This effectively shortens the test time, simplifies the test steps, and improves the test efficiency. Moreover, since the acoustic test model does not need to be removed in the middle, the scene on the two sides with and without acoustic material 2 does not change during the test state, which effectively improves the accuracy of the two test data.

[0041] The housing 11 forms an elliptical cylindrical acoustic test model. The top and bottom of this elliptical cylinder are both planar, with the top being the first end 13 and the bottom the second end 14. An adjustment device is provided at the top of the elliptical cylinder to allow rotation of the model during acoustic testing. This allows the side without the acoustic material 2 to rotate, facilitating testing of the side with the material 2 attached. This eliminates the need to remove and reinsert the acoustic test model, effectively simplifying the testing process and improving efficiency.

[0042] In this embodiment, by arranging acoustic material 2 on the sidewalls of one or more housings 11 of the sealing assembly 1, the acoustic test model simultaneously has sidewalls with and without acoustic material 2. During the acoustic test, the sealing assembly 1 is driven to rotate by a driving device, causing the positions of the housings 11 with and without acoustic material 2 to change, so as to test the acoustic test model in two and / or more states with and without acoustic material 2. This improves the testing efficiency and reduces the number of times the acoustic test model is taken out and put in during the test, which not only simplifies the operation steps but also effectively shortens the total test time.

[0043] Furthermore, by reducing the investment in acoustic test models and the number of times acoustic test scenarios are removed, the probability of changes in the acoustic test scenario environment can be reduced, thereby improving the accuracy of test results.

[0044] Furthermore, the elliptical cylindrical sealing assembly 1 is formed by the shell 11 with arc-shaped sidewalls 111, so that the size of the acoustic test model is not limited by the size required by the test scenario.

[0045] In one example, the housing 11 has an arcuate sidewall 111, and the acoustic material 2 has an attachment surface conformally to the arcuate sidewall 111, the attachment surface being conformally attached to the arcuate sidewall 111.

[0046] like Figures 1 to 5 As shown, the acoustic material 2 is conformally attached to the side wall of the housing 11, that is, the shape of the acoustic material 2 matches that of the housing 11, so as to improve the fit between the acoustic material 2 and the housing 11 and enable the acoustic material 2 and the housing 11 to fit tightly together.

[0047] For example, such as Figures 1 to 5 As shown, the housing 11 of the sealing assembly 1 has an arc-shaped sidewall 111. By providing the arc-shaped sidewall 111, the pressure resistance of the sealing assembly 1 during acoustic testing can be effectively enhanced.

[0048] The sealing assembly 1 is elliptical cylindrical, with the top of the elliptical cylinder being the first end 13 and the bottom being the second end 14. Both the first end 13 and the second end 14 of the elliptical cylinder are elliptical. The sealing assembly 1 includes a plurality of housings 11. The top of the sidewall of the housing 11 is connected to the arcuate outer periphery of the first end 13, and the bottom of the sidewall of the housing 11 is connected to the arcuate outer periphery of the second end 14. The sidewall is bent along the arcuate outer periphery to form an arcuate sidewall 111.

[0049] The acoustic material 2 matches the shape of the side wall of the housing 11, so that the bonding surface of the acoustic material 2 can be attached to the arc-shaped side wall 111, which improves the connection strength between the acoustic material 2 and the housing 11 and prevents the acoustic material 2 from detaching from the side wall of the housing 11 due to material strength or other reasons during the acoustic test, thus affecting the acoustic test results.

[0050] In this embodiment, the acoustic material 2 adopts a conformal design, that is, both the acoustic material 2 and the sidewall of the housing 11 are arc-shaped, so that the acoustic material 2 matches the shape of the sidewall of the housing 11, so as to attach the acoustic material 2 to the arc-shaped sidewall 111 of the housing 11, enhance the adhesion between the acoustic material 2 and the housing 11, effectively reduce the rebound force of the acoustic material 2 when it is attached to the sealing component 1, and improve the test accuracy.

[0051] In one example, the projection of the arcuate sidewall 111 onto a plane perpendicular to its axis is a minor arc.

[0052] like Figures 1 to 5 As shown, the shell 11 is a semi-ellipse with both the top and bottom along the major axis. The sidewalls of the shell 11 are arc-shaped steel plates, the top of which is connected to the arc-shaped edge of the semi-ellipse at the top of the shell 11, and the bottom of which is connected to the arc-shaped edge of the semi-ellipse at the bottom of the shell 11.

[0053] Of course, the housing 11 in this embodiment is not limited to the structure described above, and those skilled in the art can make it according to actual needs. For example, multiple housings 11 can be integrally formed.

[0054] like Figures 1 to 5 As shown, the sealing component 1 is elliptical cylindrical. By obtaining the dimensions of the required acoustic material 2 for testing, arc-shaped segments of the same diameter are cut, and multiple arc-shaped shell segments 11 are spliced ​​together to form an elliptical cylindrical acoustic test model. This ensures that the dimensions of the acoustic test model are consistent with those of the structure under test. Compared to a cylindrical acoustic test model, the elliptical cylindrical acoustic test model can adapt to the size requirements of the acoustic test simulation scene equipment while maintaining the curvature of the acoustic test model, effectively improving the adaptability of the acoustic test model to the acoustic scene.

[0055] For example, in existing acoustic testing simulation scenarios, the diameter of the tank used is six meters, and the diameter of the opening in the tank for placing the acoustic test model is two meters. The opening of the tank limits the placement of acoustic test models with a diameter of less than 1.8 meters.

[0056] In this application, by obtaining the diameter of the acoustic material 2 to be tested and cutting a local arc segment of that size, and the cross-section of the local arc segment being a minor arc, the arc segment is spliced ​​together to form an elliptical cylinder and / or a sealing component 1 with arc-shaped sidewalls 111. This allows the acoustic test model to not only have a model of the required test size, but also to be easily accessible within the size limits of the acoustic test scenario, effectively improving the adaptability of the acoustic test model.

[0057] The shell 11 is a semi-elliptical cylindrical structure cut along the axial direction of the elliptical cylinder. Multiple shells 11 are symmetrically spliced ​​along the major axis of the elliptical cylinder, or multiple shells 11 are integrally formed.

[0058] Acoustic material 2 is provided on the arc-shaped sidewalls 111 of one or more of the housings 11, while acoustic material 2 is not provided on the arc-shaped sidewalls 111 of another portion of the housings 11. This allows the elliptical cylindrical acoustic test model to have two test states, thereby reducing the number of times the acoustic test model is taken out and put into the acoustic test scene during the test process, simplifying the operation steps, and improving the test efficiency.

[0059] Of course, the acoustic material 2 and sealing assembly 1 in this embodiment are not limited to the above structure, and those skilled in the art can make settings according to actual needs. For example, acoustic materials 2 of different materials and sizes can be provided on multiple housings 11.

[0060] When multiple housings 11 are connected, the cross-section of the sealing assembly 1 is elliptical.

[0061] Of course, the sealing component 1 in this embodiment is not limited to the structure described above, and those skilled in the art can configure it according to actual needs. For example, the sealing component 1 is prismatic in shape.

[0062] In one example, a support assembly is provided inside the sealing cavity 12, and a plurality of the support assemblies are arranged along the axial direction of the sealing cavity 12.

[0063] like Figures 1 to 5 As shown, multiple housings 11 are connected in sequence and enclosed to form a sealed cavity 12. By setting the cavity inside the sealing assembly 1, the overall weight of the acoustic test model is effectively reduced. By setting a support assembly inside the sealed cavity 12, the pressure resistance of the sealing assembly 1 is effectively improved.

[0064] The sealing assembly 1 is elliptical cylindrical in shape, and the sealing cavity 12 is also elliptical cylindrical in shape. Multiple support components are evenly distributed along the axial direction of the sealing cavity 12, which effectively improves the pressure resistance of the sealing assembly 1. By evenly distributing multiple support components, uneven local stress is avoided, which could cause deformation of the sealing assembly 1 and affect the test results.

[0065] In one example, the support assembly includes a first reinforcing rib 121 and a second reinforcing rib 122. The first reinforcing rib 121 is respectively provided at opposite ends of the sealing cavity 12 along the axial direction, and a plurality of second reinforcing ribs 122 are provided between the two first reinforcing ribs 121. The plurality of second reinforcing ribs 122 are arranged along the axial direction of the sealing cavity 12.

[0066] like Figures 1 to 5 As shown, the two opposite ends of the sealing cavity 12 along the axial direction, namely the top and bottom of the sealing cavity 12, are the first end 13 at the top and the second end 14 at the bottom.

[0067] Two sets of first reinforcing ribs 121 are provided inside the sealing cavity 12. One set is provided at the top of the sealing cavity 12, and the other set of first reinforcing ribs 121 is provided at the bottom of the sealing cavity 12.

[0068] A plurality of second reinforcing ribs 122 are provided inside the sealing cavity 12. The plurality of second reinforcing ribs 122 are disposed between two sets of first reinforcing ribs 121, and the plurality of second reinforcing ribs 122 are evenly distributed along the axial direction of the sealing cavity 12.

[0069] The cross-section of the second reinforcing rib 122 is elliptical, and two support plates are provided inside the elliptical ring. The support plates are parallel to the minor axis of the elliptical ring. That is, the opposite ends of the support plates abut against the arc-shaped sidewalls 111 of the sealing assembly 1.

[0070] By setting the first reinforcing rib 121, the pressure resistance of the first end 13 and the second end 14 of the sealing assembly 1 is effectively improved, and by setting the second reinforcing rib 122, the pressure resistance of the outer wall of the sealing assembly 1 is effectively improved.

[0071] In one example, the acoustic test model of the conformally attached acoustic material further includes an adjustment component 3, which is disposed on the sealing component 1 and connected to a driving device. The driving device drives the adjustment component 3 to rotate about the axis of the sealing component 1.

[0072] like Figures 1 to 5As shown, the adjustment component 3 is fixedly mounted on the sealing component 1. The adjustment component 3 is connected to the driving device, which can then drive the sealing component 1 to move via the adjustment component 3. The driving device can extract and / or deploy an acoustic test model to the acoustic test scene, or it can drive the acoustic test model to rotate around the axis of the sealing component 1 to swap the positions of the shell 11 with the acoustic material 2 and the shell 11 without the acoustic material 2.

[0073] In one example, the sealing assembly 1 has a first end 13 and a second end 14 disposed opposite to each other, and the adjusting assembly 3 is disposed at the first end 13. The adjusting assembly 3 includes an adjusting member 31, and the adjusting member 31 has an adjusting hole 32. A plurality of the adjusting holes 32 are arranged in a circular array with the axis of the sealing assembly 1 as the array center.

[0074] like Figures 1 to 5 As shown, the sealing component 1 is elliptical cylindrical, with the top of the elliptical cylinder being the first end 13. An adjustment component 3 is provided at the first end 13. The adjustment component 3 is connected to an external device to rotate the elliptical cylindrical acoustic test model, thereby switching the end face with and without acoustic material 2. This allows for acoustic testing of the acoustic test model in both states, reducing the number of times the acoustic test model is removed and placed into the test scene, and improving testing efficiency.

[0075] In one example, the adjustment hole 32 extends from the arcuate sidewall 111 toward its axial direction.

[0076] like Figures 1 to 5 As shown, the adjusting member 31 is fixed to the first end 13 of the sealing assembly 1. The adjusting member 31 is provided with an adjusting hole 32. An external device is connected to the adjusting member 31 through the adjusting hole 32. The external device drives the adjusting member 31 to rotate, thereby causing the sealing assembly 1 to rotate accordingly, so that the shell 11 with the acoustic material 2 is converted to the shell 11 without the acoustic material 2.

[0077] Of course, the adjustment element 31 in this embodiment is not limited to the above structure, and those skilled in the art can make settings according to actual needs.

[0078] like Figures 1 to 5 As shown, the sealing assembly 1 has an elliptical cylindrical structure, and the adjusting hole 32 is an oblong hole. The extending direction of the oblong hole is parallel to the minor axis direction of the sealing assembly 1. The adjusting hole 32 is an oblong hole, for example, as... Figures 1 to 5As shown, the sealing assembly 1 includes a first housing and a second housing. The first housing and the second housing are elliptical cylinders in the connected state, and the first housing and the second housing are symmetrically arranged along the major axis of the elliptical cylinder. The waist-shaped hole extends from the arc-shaped sidewall 111 towards the axial direction to facilitate adjustment of the connection position between the external device and the sealing assembly 1, and to prevent the sealing assembly 1 from becoming misaligned during connection, which would lead to inaccurate test results.

[0079] In one example, the adjustment assembly 3 includes two lifting rings 33 arranged radially along the sealing cavity 12 and located at opposite ends of the adjustment member 31.

[0080] like Figures 1 to 5 As shown, two lifting rings 33 are provided at the first end 13 of the sealing assembly 1. The two lifting rings 33 are arranged along the major axis of the elliptical cylinder and are located at opposite ends of the adjusting member 31. The lifting rings 33 are connected to external equipment so that the sealing assembly 1 can be rotated by the external equipment.

[0081] By providing lifting rings 33 at opposite ends of the adjusting member 31, the stability of the sealing assembly 1 during rotation can be maintained.

[0082] According to another embodiment of this application, an acoustic testing system is provided, which includes a tank and an acoustic test model with conformally attached acoustic material as described above. During the acoustic testing process, the acoustic test model with conformally attached acoustic material is located inside the tank.

[0083] In this embodiment of the application, the acoustic test model needs to be placed inside a tank in the acoustic test simulation scenario during the test process.

[0084] For example, the tank has a diameter of six meters, and the opening for placing the acoustic test model is two meters wide. The acoustic test model in this embodiment has a first shell and a second shell, both with a diameter of two meters. An elliptical acoustic test model in this embodiment is formed by splicing together local arc segments according to the diameter of the device to be tested. This acoustic test model is a sealed structure. Acoustic material 2 is laid on the outer wall of either the first or second shell on one side of the acoustic test model. The adjustment component 3 at the top of the acoustic test model is connected to an external device, and the acoustic test model is lifted and placed into the tank for testing. After testing one side, the acoustic test model is rotated within the tank by the external device to test the other side. After the test is completed, the data from the two tests are compared to obtain the acoustic performance of the acoustic material 2.

[0085] Of course, the acoustic testing system in this application is not limited to the above structure, and those skilled in the art can set it up according to actual needs.

[0086] In one example, the acoustic testing system further includes a drive device connected to the sealing assembly 1.

[0087] In this embodiment, the drive device is connected to the adjusting member 31 and the lifting ring 33 on the sealing assembly 1. The drive device drives the elliptical cylindrical sealing assembly 1 to rotate via the lifting ring 33, and its connection with the adjusting member 31 enhances the stability of the sealing assembly 1 during rotation.

[0088] Of course, the drive device and sealing assembly 1 in this embodiment are not limited to the above-described structure, and those skilled in the art can configure them according to actual needs. For example, the drive device can also be directly connected to the sealing assembly 1.

[0089] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
