Description

Technical Field

[0001] This invention relates to the field of materials performance technology, specifically to a multidimensional high-energy sound beam stress control device. Background Technology

[0002] After the installation of metal components, the residual stress is dynamically redistributed due to changes in structural form, ambient temperature, and external loads, which can easily lead to stress concentration. Stress concentration can cause deformation, cracking, and corrosion at the welded joints of metal components, and may even seriously affect the stability, mechanical properties, and lifespan of the metal components during subsequent use. Therefore, timely and effective residual stress control must be carried out during the service of metal components to avoid safety accidents.

[0003] High-energy acoustic beam manipulation technology can quickly and effectively eliminate and homogenize residual stress in in-service components. It offers advantages such as low surface requirements, ease of generating various waveforms, short processing time, low energy consumption, and no damage to components. Therefore, it can be widely applied to the elimination and homogenization of in-service and residual stresses in metal components such as railway rails, oil and gas pipelines, castings and forgings, and additive welded parts. Therefore, there is an urgent need for a multi-dimensional high-energy acoustic beam stress manipulation device that can be easily installed on in-service components to quickly and effectively reduce and homogenize residual stress, allowing for on-site residual stress control without damaging the rails. Summary of the Invention

[0004] This invention provides a multi-dimensional high-energy acoustic beam stress control device for residual stress inside service metal components. The aim is to enable the device to be easily installed on service components to quickly and effectively reduce and homogenize the residual stress in service components, and to control the residual stress in the field without damaging the service components.

[0005] To achieve the above objectives, this invention proposes a multidimensional high-energy sound beam stress control device, employing the following technical solution:

[0006] The multidimensional high-energy acoustic beam stress control device includes a main fixed base and a side fixed base. The side fixed base is located below the side of the main fixed base and is hinged to the main fixed base via a convex rod. Both the main fixed base and the side fixed base are equipped with ultrasonic exciters via exciter fixing flanges. Magnetic switches are installed at both ends of the main fixed base and the side fixed base.

[0007] As described above, there is one main fixed base and at least one side fixed base. The multiple side fixed bases are respectively hinged to both sides of the main fixed base via convex rods. At least one ultrasonic exciter is provided on each of the main fixed base and the side fixed base. The residual stress inside the component to be regulated is reduced by ultrasonic exciters with different incident angles without damaging the component. The two ends of the main fixed base and the side fixed base are respectively attached to the surface of the component to be regulated by magnetic switches, which facilitates stress regulation of the component.

[0008] Optionally, the number and installation angle of the ultrasonic exciters mounted on the main fixed base and the side fixed base are set according to the residual stress distribution state of the component to be controlled.

[0009] As described above, the residual stress distribution inside the component to be controlled is detected in advance. Based on the concentrated area of ​​residual stress, at least two ultrasonic exciters are set on the main fixed base. The ultrasonic exciters on the main fixed base are set with different installation angles. The extended angle of the sound beam emitted by each ultrasonic exciter intersects the same stress concentration area. At least one ultrasonic exciter is set on each side fixed base. The extended angle of the sound beam emitted by each ultrasonic exciter on the side fixed base intersects the same stress concentration area. This makes the efficiency of controlling the residual stress inside the component in service higher.

[0010] Optionally, the main fixed base and the side fixed base are provided with an exciter through hole in the middle that matches the shape of the ultrasonic exciter, and multiple exciter fixing holes parallel to the central axis of the exciter through hole are provided around the exciter through hole; the two ends of the main fixed base and the side fixed base are provided with switch through holes that match the shape of the magnetic switch, and the magnetic switch is fastened to the switch through hole by bolts; one side of the main fixed base and the side fixed base is provided with a curved surface structure that fits against the surface of the component to be controlled.

[0011] As described above, the inclination angles of the exciter through holes in the middle of the main fixed base and the side fixed base are different. After the ultrasonic exciter is installed in the exciter through holes with different inclination angles, the angle of the ultrasonic exciter's emitted sound beam is also different. The ultrasonic exciter is fastened through the exciter fixing hole. The switch through holes at both ends of the main fixed base and the side fixed base are fastened with bolts to the magnetic switch. One side of the main fixed base and the side fixed base is provided with a curved surface structure, which is used to fit the surface of the component to be adjusted and complete the non-destructive reduction of residual stress.

[0012] Optionally, the lower end face of the ultrasonic exciter is in close contact with one end face of the sound-guiding curvature wedge by bolts, and the sound-guiding curvature wedge is respectively set in the exciter through hole of the main fixed base and the side fixed base.

[0013] As shown above, an exciter through hole is provided between the main fixed base and the side fixed base. The lower part of the ultrasonic exciter is installed at the upper end of the exciter through hole, and a sound-guiding curvature wedge is installed at the lower end of the exciter through hole. The high-energy ultrasonic waves emitted by the ultrasonic exciter are transmitted to the inside of the component through the sound-guiding curvature wedge to reduce the residual stress inside.

[0014] Optionally, the other end face of the sound-guiding curvature wedge is configured to conform to the curvature shape of the component to be adjusted; both ends of the sound-guiding curvature wedge are coated with a coupling medium.

[0015] As described above, the side of the acoustic curvature wedge that contacts the surface of the component to be controlled is provided with a curvature structure and is also coated with a coupling medium. The side of the acoustic curvature wedge that contacts the ultrasonic exciter is also coated with a coupling medium. The acoustic curvature wedge can reduce the loss of ultrasonic energy and allow as much ultrasonic energy as possible to be input into the component.

[0016] Optionally, the actuator fixing flange has a flange through hole at its center that matches the shape of the ultrasonic actuator, and a plurality of flange fixing holes parallel to the central axis of the flange through hole are provided around the flange through hole; the outer side wall of the actuator fixing flange has a plurality of flange thread holes that are perpendicular to the central axis of the flange through hole.

[0017] As described above, the actuator fixing flange and the ultrasonic actuator located at the flange through hole are fastened together as one unit through the flange thread hole, and the actuator fixing flange and the ultrasonic actuator are fastened to the main fixing base and the side fixing base through the flange fixing hole.

[0018] Optionally, flange fastening bolts are fitted at the flange fixing holes, and a spring is wrapped around the flange fastening bolts.

[0019] As shown above, the flange fastening bolts are fixed to the flange fixing holes by the surrounding springs, providing a certain adjustable preload for the ultrasonic exciter.

[0020] Optionally, the number of magnetic switches can be determined based on the dimensions of the main fixing base and the side fixing base.

[0021] As mentioned above, the main fixing base is generally designed to be larger than the side fixing base, and the main fixing base has more magnetic switches at both ends. Based on the dimensions of the main fixing base and the side fixing base, the number of magnetic switches on each fixing base is set to achieve a secure installation of the main fixing base and the side fixing base.

[0022] Optionally, the actuator mounting hole matches the flange mounting hole.

[0023] As described above, the exciter fixing holes are provided on the main fixing base and the side fixing base to fix the ultrasonic exciter on the main fixing base and the side fixing base. The flange fixing holes are provided on the exciter fixing flange to fix the exciter fixing flange on the main fixing base and the side fixing base. The ultrasonic exciter and the exciter fixing flange are fastened together as one unit. The two are fixed to the exciter fixing holes on the main fixing base and the side fixing base through the flange fixing holes on the exciter fixing flange. Therefore, the exciter fixing holes and the flange fixing holes are matched.

[0024] Optionally, a lifting handle is fitted on the main fixed base.

[0025] As shown above, a lifting handle is mounted on the main fixed base. The lifting handle may be provided with a threaded hole to connect with an external motion mechanism so as to remove the multidimensional high-energy sound beam stress control device from the surface of the component.

[0026] In summary, the multidimensional high-energy acoustic beam stress control device designed in this invention has a simple structure and is easy to use. It enables convenient, quick, and reliable clamping and installation of high-energy ultrasonic exciters and effective non-destructive reduction of residual stress. It ensures that the ultrasonic exciter is stably and firmly installed on the surface of the component to be treated with a certain preload, and the preload is adjustable to ensure that ultrasonic energy is effectively transmitted into the stress concentration area of ​​the component weld, thereby achieving residual stress control and reduction. The device is small in size and light in weight, and uses a magnetic switch to adsorb the device onto the surface of the rail, which can effectively achieve firm installation on the surface of ferromagnetic materials such as metal components without causing secondary damage such as indentations and deformation to the surface of the metal components.

[0027] The various technical features of the present invention and their relationships will be further explained below with reference to the accompanying drawings. The drawings are exemplary; some technical features are not shown to scale, and some drawings may omit technical features commonly used in the art to which this invention pertains that are not essential for understanding and implementing the invention, or may additionally show technical features that are not essential for understanding and implementing the invention. In other words, the combination of various technical features shown in the drawings is not intended to limit the invention. Furthermore, throughout this invention, the same reference numerals refer to the same things. Specific descriptions of the drawings are as follows:

[0029] Figure 2 This is a cross-sectional view of an example of a multidimensional high-energy acoustic beam stress control device.

[0032] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this application can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this application.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0036] This application uses in-service rails as the components to be controlled. During the rail welding process, local heating and uneven cooling inevitably lead to an unevenly distributed residual stress field after welding. After the rail is installed, the residual stress is dynamically redistributed due to changes in structural form, ambient temperature, and external loads, which easily leads to stress concentration. Stress concentration can cause deformation, cracking, and corrosion at the rail weld joints, and may even seriously affect the stability, mechanical properties, and lifespan of the rail during subsequent use. Therefore, timely and effective residual stress control must be carried out during the service of the rail to avoid safety accidents.

[0037] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. The specific embodiments described below can be combined with each other to form new embodiments. The same or similar ideas or processes described in one embodiment may not be repeated in other embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] Figure 1 The specific structure of a multidimensional high-energy sound beam controlled stress device is shown, such as... Figure 1 As shown, a multidimensional high-energy sound beam stress control device includes:

[0039] The multidimensional high-energy acoustic beam stress control device includes a main fixed base 1 and a side fixed base 2. The side fixed base 2 is located on the lower side of the main fixed base 1 and is hinged to the main fixed base 1 by a convex rod 3. Both the main fixed base 1 and the side fixed base 2 are equipped with ultrasonic exciters 4 through exciter fixing flanges 5. Both ends of the main fixed base 1 and the side fixed base 2 are equipped with magnetic switches 6.

[0040] Specifically, there is one main fixing base 1 and at least one side fixing base 2. The multiple side fixing bases 2 are respectively hinged to both sides of the main fixing base 1 by a convex rod 3. At least one ultrasonic exciter 4 is provided on the main fixing base 1 and the side fixing base 2 respectively. The residual stress inside the component 9 to be regulated is reduced by the ultrasonic exciter 4 with different incident angles without damaging the component 9. The two ends of the main fixing base 1 and the side fixing base 2 are respectively attached to the surface of the component 9 to be regulated by magnetic switches 6, which facilitates stress regulation of the component 9 to be regulated.

[0041] Optionally, the number and installation angle of the ultrasonic exciters 4 mounted on the main fixed base 1 and the side fixed base 2 are set according to the residual stress distribution state of the component 9 to be adjusted.

[0042] Specifically, the residual stress distribution inside the component 9 to be controlled is detected in advance. Based on the concentrated area of ​​residual stress, at least two ultrasonic exciters 4 are set on the main fixed base 1. The ultrasonic exciters 4 on the main fixed base 1 are set with different installation angles. The extended angle of the sound beam emitted by each ultrasonic exciter 4 intersects the same stress concentration area. At least one ultrasonic exciter 4 is set on each side fixed base 2. The extended angle of the sound beam emitted by each ultrasonic exciter 4 on the side fixed base 2 intersects the same stress concentration area. This makes the efficiency of controlling the residual stress inside the component in service higher.

[0043] In one specific embodiment, the high-energy ultrasonic waves (i.e., the control signal) emitted by the ultrasonic exciter 4 can be transverse waves and, or longitudinal waves. The parameters of the control signal emitted by the ultrasonic exciter 4 are adjustable and can be adjusted according to different materials and, or, different wall thicknesses, of the rail to adapt to different rails to be controlled. The adjustable parameters include at least frequency, amplitude, phase, waveform, and, or incident angle. By adjusting the parameters of the control signal, optimal residual stress elimination and homogenization effects can be achieved, improving the accuracy of residual stress control.

[0044] The ultrasonic exciter 4 can communicate with the controller (either via a signal line or wirelessly). The controller sends a control signal to the ultrasonic exciter 4, and after receiving the control signal, the ultrasonic exciter 4 performs residual stress ultrasonic control processing with corresponding waveform, frequency, amplitude, phase, etc.

[0045] Because high-energy ultrasound has a certain beam directivity, the multi-dimensional high-energy ultrasound beam stress control device provided in this embodiment uses an ultrasonic exciter 4 to emit multiple high-energy ultrasound beams within a certain angle range. By effectively controlling the parameters of these high-energy ultrasound beams, they are injected into a designated location within the rail material to be controlled. This achieves the purpose of reducing and homogenizing residual stress without altering the original material's lattice texture and mechanical properties. Furthermore, since the parameters of the high-energy ultrasound are adjustable in real time, the problem of material performance degradation caused by excessive energy in the focused area of ​​the high-energy ultrasound beam can be avoided, ensuring material performance. Adjusting residual stress using high-energy ultrasound has many advantages, including short time consumption, low energy, and no damage to components.

[0046] Optionally, the main fixed base 1 and the side fixed base 2 are provided with an exciter through hole that matches the shape of the ultrasonic exciter 4 in the middle, and a plurality of exciter fixing holes parallel to the central axis of the exciter through hole are provided around the exciter through hole; the main fixed base 1 and the side fixed base 2 are provided with switch through holes that match the shape of the magnetic switch 6 at both ends, and the magnetic switch 6 is fastened to the switch through hole by bolts; one side of the main fixed base 1 and the side fixed base 2 is provided with a curved surface structure that fits against the surface of the component 9 to be adjusted.

[0047] Specifically, the inclination angles of the exciter through holes provided between the main fixed base 1 and the side fixed base 2 are different. After the ultrasonic exciter 4 is installed in the exciter through holes with different inclination angles, the angle at which the ultrasonic exciter 4 emits the sound beam is also different. The ultrasonic exciter 4 is fastened through the exciter fixing hole. The switch through holes provided at both ends of the main fixed base 1 and the side fixed base 2 are fastened with bolts to the magnetic switch 6. One side of the main fixed base 1 and the side fixed base 2 is provided with a curved structure to fit the surface of the component 9 to be adjusted, so as to complete the non-destructive reduction of residual stress.

[0048] In one specific embodiment, one side of the main fixed base 1 and the side fixed base 2 is provided with a curved surface structure, which is used to conform to the rail to be adjusted. For ease of description, this application defines the side with the curved surface structure as the lower surface of the main fixed base 1 and the side fixed base 2, and the side opposite to this surface as the upper surface. It should be understood that the concepts of upper and lower surfaces are only defined for ease of description and do not constitute a limitation on the technical solution of this application.

[0049] Figure 2 This is a cross-sectional view of an example of a multidimensional high-energy acoustic beam stress control device, such as... Figure 2 As shown, the lower end face of the ultrasonic exciter 4 is in close contact with one end face of the sound-guiding curvature wedge 7 by bolts, and the sound-guiding curvature wedge 7 is respectively set in the exciter through hole of the main fixed base 1 and the side fixed base 2.

[0050] Specifically, an exciter through hole is provided between the main fixed base 1 and the side fixed base 2. The lower part of the ultrasonic exciter 4 is installed at the upper end of the exciter through hole, and a sound-guiding curvature wedge 7 is installed at the lower end of the exciter through hole. The high-energy ultrasonic waves emitted by the ultrasonic exciter 4 are transmitted to the inside of the component through the sound-guiding curvature wedge 7 to reduce the residual stress inside.

[0051] Optionally, the other end face of the sound-guiding curvature wedge 7 is configured to conform to the curvature shape of the component 9 to be adjusted; both ends of the sound-guiding curvature wedge 7 are coated with a coupling medium.

[0052] Specifically, the side of the acoustic curvature wedge 7 that contacts the surface of the component 9 to be adjusted is provided with a curvature structure and is also coated with a coupling medium. The side of the acoustic curvature wedge 7 that contacts the ultrasonic exciter 4 is also coated with a coupling medium. The acoustic curvature wedge 7 can reduce the loss of ultrasonic energy and allow as much ultrasonic energy as possible to be input into the component.

[0053] In some embodiments, one end face of the acoustic guide curvature wedge 7 is connected to the end of the ultrasonic exciter 4 via bolts or double-ended studs. The end of the ultrasonic exciter 4 is located on the lower surface of the main fixed base 1 and the side fixed base 2. The other end face of the acoustic guide curvature wedge 7 matches the shape of the rail to conform to the surface of the rail to be adjusted. A coupling medium can be applied to the contact surfaces of the ultrasonic exciter 4 and the acoustic guide curvature wedge 7, and also to the contact surfaces of the acoustic guide curvature wedge 7 and the rail to be adjusted. This allows the high-energy ultrasonic waves generated by the ultrasonic exciter 4 to be injected into the acoustic guide curvature wedge 7 through the coupling medium. The acoustic guide curvature wedge 7 then inputs the high-energy ultrasonic waves through the coupling medium to the weld of the rail to be adjusted to reduce and homogenize residual stress.

[0054] Optionally, the center of the exciter fixing flange 5 is provided with a flange through hole that matches the shape of the ultrasonic exciter 4, and a plurality of flange fixing holes parallel to the central axis of the flange through hole are provided around the flange through hole; the outer side wall of the exciter fixing flange 5 is provided with a plurality of flange thread holes that are perpendicular to the central axis of the flange through hole.

[0055] Specifically, the actuator fixing flange 5 and the ultrasonic actuator 4 located at the flange through hole are fastened together by the flange thread hole, and the actuator fixing flange 5 and the ultrasonic actuator 4 are fastened to the main fixing base 1 and the side fixing base 2 by the flange fixing hole.

[0056] In some embodiments, the outer wall of the exciter fixing flange 5 may also be provided with a horizontal flange threaded hole, which intersects perpendicularly with the flange through hole in the center of the exciter fixing flange 5, for fastening the ultrasonic exciter 4 to the exciter fixing flange 5 by screwing a set screw into the flange threaded hole.

[0057] It should be noted that the number of threaded holes on the flange can be set arbitrarily according to actual needs, as long as the ultrasonic exciter 4 can be fastened to the exciter fixing flange 5.

[0058] Optionally, a flange fastening bolt 5.1 is installed at the flange fixing hole, and a spring 5.2 is wrapped around the flange fastening bolt 5.1.

[0059] Specifically, the flange fastening bolts 5.1 are fixed to the flange fixing holes by a surrounding spring 5.2, providing a certain adjustable preload for the ultrasonic exciter 4.

[0060] In one specific embodiment, the outer wall of the actuator fixing flange 5 is provided with a horizontal flange threaded hole. The flange threaded hole intersects perpendicularly with the flange through hole at the center of the actuator fixing flange 5. The flange threaded hole is used to fasten the ultrasonic actuator 4 to the actuator fixing flange 5 with screws. By cooperating with the screws and the flange threaded hole, the ultrasonic actuator 4 can be fastened to the actuator fixing flange 5.

[0061] In one specific embodiment, by having a spring 5.2 wrapped around the flange fastening bolt 5.1, one end face of the sound-guiding curvature wedge 7 is in close contact with the stress concentration area of ​​the rail to be controlled with a certain preload, so that ultrasonic energy can be input into the interior of the rail as much as possible, thereby improving the control effect.

[0062] In some embodiments, the ultrasonic exciter 4 passes through the flange through hole on the exciter fixing flange 5 and the exciter through hole on the main fixing base 1 and the side fixing base 2. The ultrasonic exciter 4 is fixed to the main fixing base 1 and the side fixing base 2 by the exciter fixing flange 5 with a certain preload (the preload is generated by the flange fastening bolt 5.1 and the spring 5.2 that press the exciter fixing flange 5 against the main fixing base 1 and the side fixing base 2).

[0063] Optionally, the number of magnetic switches 6 can be determined according to the dimensions of the main fixed base 1 and the side fixed base 2.

[0064] Specifically, the main fixing base 1 is generally designed to be larger than the side fixing base 2, and the number of magnetic switches 6 at both ends of the main fixing base 1 is also larger. Based on the respective dimensions of the main fixing base 1 and the side fixing base 2, the number of magnetic switches 6 on each fixing base is set to achieve a secure installation of the main fixing base 1 and the side fixing base 2.

[0065] In one specific embodiment, multiple magnetic switches 6 are provided, symmetrically arranged at both ends of the main fixed base 1 and the side fixed base 2. The magnetic switches 6 can magnetically attract the main fixed base 1 and the side fixed base 2 to the rail, thereby improving the stability of the installation of the main fixed base 1 and the side fixed base 2 with the rail.

[0066] In some embodiments, the number of magnetic switches 6 can be one or more. The more magnetic switches 6 there are, the stronger the magnetic attraction, thus more firmly fixing the multidimensional high-energy sound beam stress control device to the surface of the rail to be controlled. The number of switch through holes can be determined based on the number of magnetic switches 6; that is, the main fixing base 1 and the side fixing base 2 are provided with a corresponding number of switch through holes depending on how many magnetic switches 6 are included in the multidimensional high-energy sound beam stress control device. In this embodiment, as... Figure 1 The structural diagram shown indicates that the number of magnetic switches 6 can be set to 6, and correspondingly, the number of switch through holes is also 6.

[0067] The end of the magnetic switch 6 is located on the lower surface of the main fixed base 1 and the side fixed base 2, and the corresponding switch end of the magnetic switch 6 is located on the upper surface of the main fixed base 1 and the side fixed base 2.

[0068] The magnetic switch 6 can control its own magnetism through its switch state. That is, when the work starts, the magnetic switch 6 is turned on to generate a strong magnetism to attract the rail to be adjusted. When the work ends, the magnetic switch 6 is turned off to make its magnetic attraction disappear, thereby removing the rail to be adjusted.

[0069] Optionally, the actuator mounting hole matches the flange mounting hole.

[0070] Specifically, the exciter fixing holes are provided on the main fixing base 1 and the side fixing base 2 to fix the ultrasonic exciter 4 on the main fixing base 1 and the side fixing base 2. The flange fixing holes are provided on the exciter fixing flange 5 to fix the exciter fixing flange 5 on the main fixing base 1 and the side fixing base 2. The ultrasonic exciter 4 and the exciter fixing flange 5 are fastened together as one unit. The two are fixed to the exciter fixing holes on the main fixing base 1 and the side fixing base 2 through the flange fixing holes on the exciter fixing flange 5. Therefore, the exciter fixing holes and the flange fixing holes are matched.

[0071] In some embodiments, the actuator fixing flange 5 has an actuator through hole at its center that matches the shape of the ultrasonic actuator 4. Around this actuator through hole, longitudinal flange fixing holes are provided on the actuator fixing flange 5. These flange fixing holes match the actuator fixing holes on the main fixing base 1 and the side fixing base 2, and are used to press the actuator fixing flange 5 against the main fixing base 1 and the side fixing base 2 using flange fastening bolts 5.1 and springs 5.2. The number of actuator fixing holes and flange fixing holes is generally matched, such as... Figure 1 In the illustrated embodiment, the number of actuator mounting holes and flange mounting holes is set to 6; in other embodiments, this number may vary.

[0072] Optionally, a lifting handle 8 is fitted on the main fixed base 1.

[0073] Specifically, the main fixed base 1 is equipped with a lifting handle 8, which may be provided with a threaded hole to connect with an external motion mechanism so as to remove the multidimensional high-energy sound beam stress control device from the surface of the component.

[0074] In a specific embodiment where the rail is the adjustable component 9, such as Figure 1As shown, the present invention provides a multidimensional high-energy sound beam stress control device for fixing an ultrasonic exciter 4, so that the ultrasonic exciter 4 is in close contact with the area to be controlled on the rail through the sound-guiding curvature wedge 7.

The actuator fixing holes on seat 2 are matched to fix the actuator fixing flange 5 to the main fixing base 1 and the side fixing base 2. The flange fixing holes are provided with pre-tightening force for the ultrasonic actuator by flange fastening bolts 5.1 surrounding the spring 5.2. The ultrasonic actuator 4 passes through the actuator through hole in the main fixing base 1 and the flange through hole of the actuator fixing flange 5, and is fixed to the main fixing base 1 through the actuator fixing flange 5. The ultrasonic actuator 4 passes through the actuator through hole in the side fixing base 2 and the flange through hole of the actuator fixing flange 5, and is fixed to the side fixing base 2 through the actuator fixing flange 5. The end of the ultrasonic actuator 4 is connected to the upper contact surface of the sound guiding curvature wedge 7, and the lower contact surface of the sound guiding curvature wedge 7 is the curvature shape of the rail to be adjusted.

[0075] In the above specific embodiment, the multidimensional high-energy acoustic beam stress control device is fixed to the rail by a magnetic switch 6. Then, high-energy ultrasonic waves are injected into the stress concentration area through the cooperation of the ultrasonic exciter 4 and the sound-guiding curvature wedge 7, thereby reducing and homogenizing the residual stress at the welded part of the rail. This multidimensional high-energy acoustic beam stress control device can reduce and homogenize residual stress without changing the existing rail welding process. It is small in size, lightweight, and easy to use. The magnetic switch 6 adheres to the rail, effectively ensuring a secure installation without causing secondary damage such as indentations or deformation to the rail. Furthermore, when the ultrasonic exciter 4 is fixed to the main and side fixing bases via the exciter fixing flange 5, the preload is adjustable, ensuring that the control signal can be effectively transmitted to the interior of the residual stress concentration area of ​​the rail, thus improving the control effect.
