[0029] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

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

[0034] According to one embodiment of the present application, an acoustic test model of a conformally attached acoustic material is provided, and the acoustic test model of the conformally attached acoustic material includes a sealing assembly 1; the sealing assembly 1 includes a first shell 11 and a second shell 12, the first shell 11 is connected to the second shell 12, and one of the first shell 11 and the second shell 12 is provided with an acoustic material 2. During the acoustic test, the sealing assembly 1 is connected to a driving device, and the driving device drives the sealing assembly 1 to rotate around its own axis.

[0035] like Figures 1 to 5 As shown, the device is used to test the acoustic performance of acoustic materials. The acoustic test is performed by placing the device in a tank simulating an acoustic scene.

[0036] The acoustic test model of the conformally attached acoustic material includes a sealing component 1, and the sealing component 1 includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 are steel plates, and the side walls of the first shell 11 and the second shell 12 are arc-shaped. The first shell 11 and the second shell 12 are connected to form an elliptical cylinder-shaped acoustic test model. By setting the acoustic test model to an elliptical cylinder, the pressure resistance of the acoustic test model during the acoustic test process can be effectively improved.

[0037] An acoustic material 2 to be tested is arranged on the outside of the first shell 11 or the second shell 12. The elliptical cylindrical acoustic test model is arranged to have the acoustic material 2 on one side and no acoustic material 2 on the other side. The acoustic test model is placed in a water tank for acoustic testing. The acoustic test model only needs to be rotated to detect test data in two states, with and without the acoustic material 2. This effectively shortens the test time, simplifies the test steps, and improves the test efficiency. Furthermore, since there is no need to take out the acoustic test model midway, the scenes on the two sides with the acoustic material 2 and without the acoustic material 2 do not change during the test state, which effectively improves the accuracy of the two test data.

[0038] The first shell 11 and the second shell 12 are connected to form an elliptical acoustic test model. The top and bottom of the elliptical cylinder are both flat, with the top being the first end 13 and the bottom being the second end 14. By arranging an adjustment device at the top of the elliptical cylinder, the elliptical acoustic test model can be rotated during the acoustic test process, so that the side without the acoustic material 2 can be rotated, so that the side with the acoustic material 2 can be tested, and there is no need to take out and put in the acoustic test model, which effectively simplifies the test steps and improves the test efficiency.

[0039] In an embodiment of the present application, by disposing acoustic material 2 on one of the first shell 11 and the second shell 12, the acoustic test model has acoustic material 2 on one side and no acoustic material 2 on the other side. During the acoustic test, the sealing assembly is driven to rotate by a driving device to change the positions of the first shell and the second shell, so as to test the acoustic test model in two states, with and without acoustic material 2. This reduces the number of times the acoustic test model is taken out and placed during the test, which not only simplifies the operating steps, but also effectively shortens the total test time, thereby improving the test efficiency.

[0040] In addition, by reducing the number of times the acoustic test model is invested and the number of times the acoustic test scene is taken out, the probability of changes in the acoustic test scene environment can be reduced and the accuracy of the test results can be improved.

[0041] Furthermore, an elliptical cylindrical sealing assembly is formed by the first shell and the second shell having arc-shaped side walls, so that the size of the acoustic test model is not limited to the size required by the test scenario.

[0042] In an example, both the first shell 11 and the second shell 12 have arc-shaped side walls, and the acoustic material 2 is conformally attached to the arc-shaped side walls of the first shell 11 and / or the second shell 12 .

[0043] like Figures 1 to 5 As shown, the acoustic material 2 is conformally attached to the first shell 11 and / or the second shell 12, that is, the shape of the acoustic material 2 matches the shape of the first shell 11 and / or the second shell 12, so as to improve the fit between the acoustic material 2 and the first shell 11 and / or the second shell 12, and the acoustic material 2 can fit tightly with the first shell 11 and / or the second shell 12.

[0044] like Figures 1 to 5 As shown, the first shell 11 and the second shell 12 form an elliptical cylinder, the top of the elliptical cylinder is the first end 13, the bottom is the second end 14, and the first end 13 and the second end 14 of the elliptical cylinder are both elliptical. The side walls of the first shell 11 and the second shell 12 are bent along the outer periphery of the ellipse to form an arc shape.

[0045] The opening of the existing acoustic test simulation scene for placing the acoustic test model has a limited size. By setting the acoustic test model to an elliptical cylinder, the size requirements of the acoustic test simulation scene equipment are adapted while ensuring the curvature of the acoustic test model.

[0046] In the embodiment of the present application, the acoustic material 2 adopts a conformal design, that is, the side walls of the acoustic material 2 and the first shell 11 and / or the second shell 12 are all arc-shaped, so that the acoustic material 2 matches the side wall shape of the first shell 11 or the second shell 12, so as to facilitate the acoustic material 2 to be bonded to the first shell 11 and the second shell 12, strengthen the degree of fit between the acoustic material 2 and the first shell 11 or the second shell 12, effectively avoid the bending rebound force of the acoustic material 2 when it is bonded to the sealing assembly 1, weaken the possible influence of the internal bending prestress of the acoustic material on its acoustic performance, and improve the test accuracy.

[0047] The acoustic material 2 is processed by conformal design. Compared with the traditional flat-plate acoustic material bending and lamination, the conformal-designed acoustic material 2 can effectively avoid the bending rebound force of the material, weaken the possible influence of the internal bending prestress of the acoustic material 2 on its acoustic performance, and improve the accuracy of the acoustic performance test.

[0048] Of course, in the embodiment of the present application, the acoustic material 2 and the acoustic test model are not limited to the above structure, and those skilled in the art can set them according to actual needs. For example, the first shell 11 and the second shell 12 adopt a conformal design of curved side walls, which maintains the curvature of the acoustic material 2 on the actual equipment, so that the acoustic test scene in the tank is closer to the actual application conditions, and the test results can more accurately reflect the actual application effect.

[0049] In an example, when the first shell 11 and the second shell 12 are in a connected state, the sealing assembly 1 is in an elliptical column shape, and the first shell 11 and the second shell 11 are symmetrically arranged with the long axis of the sealing assembly 1 as the center.

[0050] like Figures 1 to 5 As shown, the first shell 11 is semi-elliptical with the top and bottom both along the long axis direction. The side wall of the first shell 11 is an arc-shaped steel plate, the top of the arc-shaped steel plate is connected to the arc-shaped edge of the semi-ellipse at the top of the first shell 11, and the bottom of the arc-shaped steel plate is connected to the arc-shaped edge of the semi-ellipse at the bottom of the first shell 11.

[0051] Of course, in the embodiment of the present application, the first housing 11 and the second housing 12 are not limited to the above structure, and those skilled in the art can configure them according to actual needs. For example, the first housing 11 and the second housing 12 can be integrally formed.

[0052] like Figures 1 to 5As shown, the sealing assembly 1 is in the shape of an elliptical cylinder. By obtaining the size of the required test acoustic material 2, the first shell 11 and the second shell 12 with the same diameter arc segment are intercepted, and the first shell 11 and the second shell 12 are spliced ​​to form an elliptical cylinder acoustic test model, so as to avoid the acoustic test model with a cylindrical structure from being unable to enter the acoustic test scene due to size limitations. By setting the acoustic test model to an elliptical cylinder, the adaptability of the acoustic test model to the acoustic scene is effectively improved.

[0053] For example, the diameter of the tank used in the existing acoustic test scene is six meters, and the opening diameter of the tank for placing the acoustic test model is two meters. Some necessary installation accessories are also provided at the mouth of the pipe. To facilitate the hoisting of the test model, the tank is usually limited to a cylindrical acoustic test model with a diameter of less than 1.8 meters. In this application, by obtaining the diameter of the acoustic material to be tested, intercepting a local arc segment of this size, and splicing it to form an elliptical acoustic test model, not only can a model of the required test size be obtained, but it is also easy to enter the size limited by the acoustic test scene, effectively improving the adaptability of the acoustic test model.

[0054] The first shell 11 and the second shell 12 are semi-elliptical cylinder structures cut along the axial direction of the elliptical cylinder. The first shell 11 and the second shell 12 are symmetrically spliced ​​along the long axis of the elliptical cylinder, or the first shell 11 and the second shell 12 are integrally formed.

[0055] Acoustic material 2 is set on the curved side wall of the first shell 11, and there is no acoustic material 2 on the curved side wall of the second shell 12, so that the elliptical cylindrical acoustic test model has two states to be tested, so as to reduce the number of times the acoustic test model is taken out and put into the acoustic test scene during the test process, simplify the operation steps, and improve the test efficiency.

[0056] Of course, in the embodiment of the present application, the acoustic material 1 and the sealing assembly 1 are not limited to the above structure, and those skilled in the art can set them according to actual needs. For example, the acoustic material 2 can also be set in the second shell 12, and the first shell 11 has no acoustic material 2.

[0057] The first shell 11 and the second shell 12 are of the same shape and size. The first shell 11 and the second shell 12 are symmetrically arranged and connected to form a sealing assembly 1. That is, when the first shell 11 and the second shell 12 are connected, the cross section of the sealing assembly 1 is elliptical.

[0058] Of course, in the embodiment of the present application, the sealing assembly 1 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the sealing assembly 1 is prismatic, and the cross-sections of the first shell 11 and the second shell 12 are trapezoidal.

[0059] In an example, a sealed cavity 15 is defined between the first shell 11 and the second shell 12 . A support assembly is disposed in the sealed cavity 15 . A plurality of the support assemblies are arranged along the axial direction of the sealed cavity 15 .

[0060] like Figures 1 to 5 As shown, there is a sealed cavity 15 between the first shell 11 and the second shell 12. By setting the sealing component 1 as a cavity, the overall weight of the acoustic test model is effectively reduced. By setting a supporting component in the sealed cavity 15, the pressure resistance of the first shell 11 and the second shell 12 is effectively improved.

[0061] The sealing assembly 1 is in the shape of an elliptical cylinder, and the sealing cavity 15 is in the shape of an elliptical cylinder. Multiple support assemblies are evenly arranged along the axial direction of the sealing cavity 15, effectively improving the pressure resistance of the first shell 11 and the second shell 12. By evenly distributing multiple support assemblies, deformation of the sealing assembly 1 caused by uneven local force is avoided, which affects the test results.

[0062] In one example, the support assembly includes a first reinforcing rib 151 and a second reinforcing rib 152, the first reinforcing ribs 151 are respectively provided at the opposite ends of the sealing cavity 15 along the axial direction, a plurality of the second reinforcing ribs 152 are provided between the two first reinforcing ribs 151, and the plurality of the second reinforcing ribs 152 are arranged along the axial direction of the sealing cavity 15.

[0063] like Figures 1 to 5 As shown, the two opposite ends of the sealed cavity 15 along the axial direction, namely the top and the bottom of the sealed cavity 15 , the top of the sealed cavity 15 is the first end, and the bottom of the sealed cavity 15 is the second end.

[0064] Two groups of first reinforcing ribs 151 are arranged in the sealed cavity 15 , one group is arranged at the top of the sealed cavity 15 , and the other group of first reinforcing ribs 151 is arranged at the bottom of the sealed cavity 15 .

[0065] A plurality of second reinforcing ribs 152 are disposed in the sealing cavity 15 . The plurality of second reinforcing ribs 152 are disposed between the two groups of first reinforcing ribs 151 , and the plurality of second reinforcing ribs 152 are evenly distributed along the axial direction of the sealing cavity 15 .

[0066] The cross section of the second reinforcing rib 152 is an elliptical ring, and two support plates are arranged inside the elliptical ring. The support plates are parallel to the short axis of the elliptical ring, that is, the opposite ends of the support plates are respectively against the arc-shaped side walls of the first shell 11 and the second shell 12.

[0067] The first reinforcing rib 151 is provided to effectively improve the pressure resistance of the first end 13 and the second end 14 of the sealing assembly 1 , and the second reinforcing rib 152 is provided to effectively improve the pressure resistance of the outer wall of the sealing assembly 1 .

[0068] In one example, the acoustic test model of the conformally attached acoustic material also includes an adjustment component 3, which is disposed on the sealing component 1, and the adjustment component 3 is connected to a driving device, and the driving device drives the adjustment component 3 to rotate around the axis of the sealing component 1.

[0069] like Figures 1 to 5 As shown, the adjustment component 3 is fixedly arranged on the sealing component 1, and is connected to the driving device through the adjustment component 3, so that the driving device can drive the sealing component 1 to move through the adjustment component 3. The driving device can extract and / or put the acoustic test model into the acoustic test scene, and the driving device can also drive the acoustic test model to rotate around the axis of the sealing component 1 to exchange the positions of the first shell 11 and the second shell 12.

[0070] In one example, the sealing assembly 1 has a first end 13 and a second end 14 that are relatively arranged, and the adjustment assembly 3 is arranged at the first end 13, wherein the adjustment assembly 3 includes an adjustment member 31, and an adjustment hole 32 is opened on the adjustment member 31, and the plurality of adjustment holes 32 are distributed in a circular array with the axis of the sealing assembly 1 as the array center.

[0071] like Figures 1 to 5 As shown, the sealing component 1 is in the shape of an elliptical cylinder, and the top of the elliptical cylinder is a first end 13. An adjustment component 3 is provided at the first end 13, and is connected to an external device through the adjustment component 3 to drive the elliptical cylinder-shaped acoustic test model to rotate, so that the end faces without acoustic material 2 and with acoustic material 2 are converted, so as to perform acoustic tests on the acoustic test models in the two states, reduce the number of times the acoustic test model is taken out and put into the test scene, and improve the test efficiency.

[0072] In an example, the extending direction of the adjustment hole 32 extends from the first shell 11 to the second shell 12 .

[0073] like Figures 1 to 5 As shown, the adjusting member 31 is fixed to the first end 13 of the sealing assembly 1, and an adjusting hole 32 is provided on the adjusting member 31. The external device is connected to the adjusting member 31 through the adjusting hole 32. The adjusting member 31 is driven to rotate by the external device, and then the sealing assembly 1 rotates accordingly, so that the first shell 11 and the second shell 12 are switched, that is, the side with the acoustic material 2 and the side without the acoustic material 2 are switched.

[0074] Of course, in the embodiment of the present application, the adjusting member 31 is not limited to the above structure, and those skilled in the art can configure it according to actual needs.

[0075] like Figures 1 to 5As shown, the sealing component 1 is an elliptical column structure, and the adjustment hole 32 is a waist-shaped hole. The extension direction of the waist-shaped hole is parallel to the short axis direction of the sealing component 1. By setting the waist-shaped hole, it is convenient to adjust the connection position between the external device and the sealing component 1, so as to avoid the sealing component 1 being skewed during connection, resulting in inaccurate test results.

[0076] In one example, the adjustment assembly 3 includes a connecting member 33 , and two connecting members 33 are arranged along the radial direction of the sealing assembly 1 .

[0077] like Figures 1 to 5 As shown, two connecting members 33 are provided at the first end 13 of the sealing assembly 1, the two connecting members 33 are arranged along the long axis direction of the elliptical cylinder, and the two connecting members 33 are respectively located at opposite ends of the adjusting member 31. The connecting members 33 are connected to an external device so that the sealing assembly 1 can be driven to rotate by the external device.

[0078] By respectively arranging connecting members 33 at the opposite ends of the adjusting member 31, not only can the acoustic test model be suspended by a lifting rope during the lifting process so as to place the acoustic test model into the tank body for acoustic testing, but also the stability of the sealing assembly 1 during rotation in the tank body can be improved.

[0079] According to another embodiment of the present application, an acoustic testing system is provided, which includes a tank body and an acoustic testing model of the conformally attached acoustic material as described above. During the acoustic testing process, the acoustic testing model of the conformally attached acoustic material is located in the tank body.

[0080] In an embodiment of the present application, the acoustic test model needs to be placed into a tank of an acoustic test simulation scenario during the test.

[0081] For example, the diameter of the tank is six meters, and the opening for placing the acoustic test model is two meters. Since some necessary installation accessories are also provided at the pipe mouth, in order to facilitate the lifting of the test model, the tank is usually limited to the acoustic test model with a diameter of less than 1.8 meters.

[0082] The first shell 11 and the second shell 12 of the acoustic test model in the embodiment of the present application are arc segments cut from a cylindrical structure with a diameter of two meters. The elliptical acoustic test model in the embodiment of the present application is formed by splicing the local arc segments according to the diameter size of the device to be tested. The acoustic test model is a sealed structure. Acoustic material 2 is arranged on the outer wall of one side of the acoustic test model, i.e., the first shell 11 or the second shell 12. The adjustment component 3 on 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 the test on one side is completed, the acoustic test model is driven to rotate in the tank by an external device, and the other side of the acoustic test model is tested. After the test is completed, the two test data and other information are compared to obtain the acoustic performance of the acoustic material 2.

[0083] Of course, in the embodiment of the present application, the acoustic testing system is not limited to the above structure, and those skilled in the art can configure it according to actual needs.

[0084] In one example, the acoustic testing system further includes a driving device connected to the sealing assembly 1 .

[0085] In the embodiment of the present application, the driving device is connected to the adjusting member 31 and the connecting member 33 on the sealing assembly 1. The driving device drives the elliptical cylindrical sealing assembly 1 to rotate through the connecting member 33, and the connection with the adjusting member 31 can enhance the stability of the sealing assembly 1 during the rotation process.

[0086] Of course, in the embodiment of the present application, the driving device and the sealing assembly 1 are not limited to the above structure, and those skilled in the art can make configurations according to actual needs. For example, the driving device can also be directly connected to the sealing assembly 1 .

[0087] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
