Description

Technical Field

[0001] This invention relates to the field of structural impact dynamics and material micromechanics testing technology, specifically to an intelligent testing device and method for the impact life of filaments suitable for synchrotron radiation sources. Background Technology

[0002] High-strength wires, due to their superior mechanical properties and durability, play an irreplaceable role in various impact-resistant safety protection systems. They are widely used in transportation, construction, and aviation, with typical applications including highway guardrails, building explosion-proof netting, and aircraft carrier arresting gear. Compared to complex structures such as cables or wire meshes, single-wire studies allow for more precise control of experimental variables (such as impact angle, strain rate, and surface contact), thereby eliminating the coupling effects of multiple factors and focusing on the dynamic mechanical behavior of the material itself. Furthermore, the microstructural evolution of the wire during impact (such as grain orientation and dislocation density) has a significant impact on its dynamic mechanical properties. Using synchrotron radiation sources, real-time, in-situ monitoring of microstructural changes during wire impact can be achieved, providing advanced experimental methods for a deeper understanding of the dynamic failure mechanisms of wires.

[0003] Currently, the mechanical property testing of filaments mainly focuses on static or axial impact loads, making it difficult to effectively simulate and measure the dynamic response of filaments under transverse impact loads. Microstructure characterization largely relies on post-analysis methods such as fracture surface observation and CT scans, which cannot achieve real-time dynamic monitoring of the filament impact process, resulting in incomplete data acquisition. To observe the evolution of microstructures in real time using synchrotron radiation sources, the problem of experimental repeatability needs to be solved (requiring bullet velocity error of less than 0.10 m / s and high-speed camera synchronization error of less than 100 microseconds). At the same time, existing devices generally lack automatic cyclic impact and intelligent fracture detection functions, making it difficult to meet the needs of efficient and accurate filament impact life dynamic testing.

[0004] In summary, current methods for testing the mechanical properties of wires and for characterizing their microstructures are insufficient to meet the requirements for efficient and accurate dynamic testing of the impact life of wires, and cannot be linked with synchrotron radiation sources to achieve real-time dynamic monitoring of microstructures.

[0024] The technical solution of the present invention 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 the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The present invention will be further explained below with reference to specific embodiments.

[0026] like Figure 1As shown in the figure, this embodiment provides an intelligent testing device for the impact life of filaments suitable for synchrotron radiation sources, including a filament fixing system, an intelligent prestress control system, an intelligent bullet position control system, an intelligent electromagnetic drive control system, a high-precision laser velocity measurement control system, a high-speed imaging control system suitable for synchrotron radiation sources, and a computer host control system.

[0027] This filament fixing system provides fixing components and a filament sample for stress-free filament fixing. The fixing components include an aluminum alloy drive wheel 11, an optical axis 12, an optical axis cross clamp 13, an optical breadboard 14, a PCA10 optical support rod 15, a ribbed vertical support plate 16, a horizontal support plate 17, and a filament sample 18. The ribbed vertical support plate 16 is vertically fixed to the upper part of an external optical platform, with a pair of horizontal support plates 17 arranged vertically on one side of its middle section. Both the head and root of the pair of horizontal support plates 17 are equipped with pulleys, and the distance between the pair of horizontal support plates 17 is the effective length of the filament sample 18. The optical breadboard 14 is horizontally positioned on one side of the horizontal support plate 17 above the ribbed vertical support plate 16, with a pair of optical axis cross clamps 13 symmetrically mounted on its upper part. A PCA10 optical support rod 15 is vertically fixed to the upper part of each optical axis cross clamp 13.

[0028] The optical axis 12 has a pair, with one optical axis 12 horizontally located on one side of a horizontal support plate 17 above the ribbed vertical support plate 16. One end of the optical axis 12 is clamped and fixed by a pair of optical axis cross clamps 13, and the other end extends horizontally towards one side of the middle section of the ribbed vertical support plate 16, with a drive wheel 11 installed at the end. The other optical axis 12 is matched and horizontally positioned below the horizontal support plate 17 located below the ribbed vertical support plate 16. Another pair of optical axis cross clamps 13 are symmetrically fixed at both ends of the optical axis 12, and a PCA10 optical support rod 15 is vertically installed on each optical axis cross clamp 13. Another aluminum alloy drive wheel 11 is installed in the middle section. The lower end of each optical axis cross clamp 13 extends downwards and is connected to the measuring component of the intelligent prestressed control system.

[0029] The drive wheel 11, optical axis 12, and optical axis cross clamp 13 need to fit tightly to ensure the stability and accuracy of the filament sample 18 during the testing process. The drive wheel 11 has a threaded hole running through it along the axial direction for fixing the filament sample 18 to the drive wheel 11 and fixing the drive wheel 11 to the optical axis 12. The filament sample 18 is wound around the drive wheel 11 after passing over the pulleys on the pair of horizontal support plates 17, in order to eliminate unnecessary stress concentration. The optical axis 12 and the PCA10 optical support rod 15 are both fixed with the cross clamp 13. The PCA10 optical support rod 15 is connected to the electric servo motor component of the intelligent prestress control system through the optical breadboard 14.

[0030] The intelligent prestress control system provides an electric servo motor component for precisely controlling the prestress of the wire sample 18 and a measuring component for measuring the prestress, and provides a prestress controller 23 for real-time control of the automatic servo motor component; wherein, the electric servo motor component is a DC stroke electric push rod 21, the upper end of which is fixedly connected to the bottom of the optical breadboard 14; the measuring component is an S-shaped force gauge 22; the S-shaped force gauge 22 is used as a force sensor to capture the analog signal of the prestress of the steel wire and is usually connected to a digital transmitter for integrated use. The digital transmitter converts the analog signal of the prestress into a digital signal and sends it to the prestress controller 23; the S-shaped force gauge 22 is set on the upper part of the optical platform, and its upper end is fixedly connected to the lower end of the PCA10 optical support rod 15 located below the horizontal support plate 17 on the lower side of the ribbed vertical support plate 16. The prestress controller 23 is located on the upper part of the optical platform. The DC stroke motor push rod 21 and the S-shaped force gauge 22 are connected to the prestress controller 23 through signal lines. When the prestress controller 23 receives the program command issued by the computer host 71, it can automatically adjust the prestress to the set value.

[0031] The intelligent bullet position control system provides a one-way valve component and a linear module component for controlling the initial position of the bullet, and provides a bullet position controller 35 for controlling the one-way valve component and the linear module component. The one-way valve component includes a one-way valve 31 and a bullet blocking baffle 32. The one-way valve 31 is fitted above the barrel 41, ensuring that its head can fall into the barrel 41 under gravity, preventing the bullet 46 from passing through. Simultaneously, it ensures that when the one-way valve 31 is energized and lifted, it can completely leave the barrel, allowing the bullet 46 to pass through. The bullet blocking baffle 32 is installed at the rear of the barrel 41, near the linear module 33. Its function is that during cyclic impact, after the square ferromagnetic bullet is rebounded by the taut wire sample 18, it can remain between the bullet blocking baffle 32 and the one-way valve 31, preventing it from impacting the linear module 33. The linear module component includes a linear module 33 and a horizontal slender rod 34. The linear module 33 is fitted onto the upper part of an optical platform located on one side of the bullet arresting baffle 32. One end of the horizontal slender rod 34 is fixed to the upper part of the linear module 33, and is pressed together with a slide (which generally has a threaded hole) on the linear module 33 by screws and a standard pressure plate. The other end extends horizontally outward from the outside of the linear module 33, passes through the bullet arresting baffle 32, and is connected to the drive component of the intelligent electromagnetic drive control system. The bullet position controller 35 is also located on the upper part of the optical platform. When a bullet is placed between the one-way valve 31 and the bullet arresting baffle 32, the bullet position controller 35 automatically adjusts the bullet position to the set value after receiving a program command from the computer host 71.

[0032] This intelligent electromagnetic drive control system provides the drive and launching components required for electromagnetic drive loading, and provides an electromagnetic drive controller 45 for controlling the drive components. The drive components include a square barrel 41, a copper coil 42, a capacitor 43, and a programmable high-voltage power supply 44. The square barrel 41 is connected to a bullet-stopping baffle 32, which is in turn connected to an optical platform via a support column. The copper coil 42 is wound around the outer wall of the square barrel 41 at specific intervals. The capacitor 43 is located on the upper part of the optical platform and is used to provide pulsed current to the copper coil 42. The programmable high-voltage power supply 44 is located on the upper part of the optical platform and is used to charge the capacitor 43. The launching component is a square ferromagnetic bullet, placed inside the square barrel 41. The size of the square ferromagnetic bullet matches the inner diameter of the square barrel 41 to ensure that the square ferromagnetic bullet does not rotate. The electromagnetic drive controller 45 is located on one side of the programmable high-voltage power supply 44 and is connected to both the capacitor 43 and the programmable high-voltage power supply 44. The copper coil 42 uses electromagnetic energy to drive the square ferromagnetic bullet to accelerate along the inner wall of the square cannon barrel 41, and after reaching the set speed, it impacts the wire sample 18; when the electromagnetic drive controller 45 receives the program instruction issued by the computer host 71, it can automatically adjust the voltage of the capacitor 43 to the set value and drive the square ferromagnetic bullet to impact the wire sample 18.

[0033] This high-precision laser velocity measurement control system provides a velocity sensor for measuring the velocity of a square ferromagnetic bullet and a velocity data acquisition device for collecting velocity data. The velocity sensor is a laser velocity measurement module 51, which is matched and positioned below the square cannon barrel 41 to measure the velocity of the square ferromagnetic bullet. The velocity data acquisition device is an oscilloscope 52, mounted on the upper part of the optical platform. The oscilloscope 52 is electrically connected to a computer host 71 via a network cable. After receiving program instructions from the computer host 71, the oscilloscope 52 automatically adjusts its parameters and enters a ready state. The oscilloscope 52 is electrically connected to the laser velocity measurement module 51. When the square ferromagnetic bullet reaches the location of the laser velocity measurement module 51, the laser velocity measurement module 51 sends an upward signal to the oscilloscope 52. The velocity of the square ferromagnetic bullet is obtained by dividing the length of the square ferromagnetic bullet by the light-blocking time measured in the oscilloscope 52. After each trigger, the computer host 71 sends program instructions to the oscilloscope 52 to save the waveform data.

[0034] This high-speed imaging control system for synchrotron radiation sources provides a light source control component for controlling the synchrotron radiation source, a high-speed camera component for recording the impact process, and a high-speed imaging controller for controlling the light source control component and the high-speed camera component. The light source control component is a shutter 61 that can be controlled by a voltage signal, used to control the opening and closing of the synchrotron radiation source. It is located on the outer side of the square barrel 41 of the high-precision laser velocimetry control system near the end of the filament sample 18. The high-speed camera component includes a high-speed camera 62, a high-speed camera lens 63, and a reflector 64 containing a scintillator. The reflector 64 has a pair and is respectively disposed on one side of the ribbed vertical support plate 16 of the filament fixing system. The high-speed camera 62 is matched and located on the outer side of one side of the ribbed vertical support plate 16 and distributed on opposite sides of the shutter 61 on the outer side of the ribbed vertical support plate 16. A high-speed camera lens 63 is mounted on its head to convert X-rays passing through the filament sample 18 into visible light, which is then reflected by the reflector 64, imaged by the high-speed camera lens 63, and focused onto the high-speed camera 62. The signal synchronization component is a synchronization signal generator 65, which is located on the upper part of the optical platform. It is used to generate a delay signal to trigger the shutter 61 and the high-speed camera 62. The synchronization signal generator 65 is connected to the computer host 71 via a network cable. After receiving the program instructions from the computer host 71, it can automatically adjust the delay time of the synchronization signal generator 65 to the set value and enter the standby state. The synchronization signal generator 65 is connected to the laser speed measurement module 51. When the square ferromagnetic bullet reaches the location of the laser speed measurement module 51, it sends a rising edge signal to the synchronization signal generator 65 as an external trigger signal. After each trigger, the computer host 71 sends a program instruction to the high-speed camera 62 to save the image data.

[0035] The computer host control system provides a computer host 71, which programs the system to send instructions to the intelligent prestressed control system, intelligent bullet position control system, intelligent electromagnetic drive control rod system, high-precision laser velocity measurement control system, and high-speed imaging control system suitable for synchrotron radiation sources. The prestressed controller 23, bullet position controller 35, and electromagnetic drive controller 46 are all connected to the computer host 71 via signal lines. The computer host 71 programs and sends instructions to the prestressed controller 23, bullet position controller 35, and electromagnetic drive controller 46, thereby automatically controlling the intelligent prestressed control system, intelligent bullet position control system, and intelligent electromagnetic drive control system. The oscilloscope 52, high-speed camera 62, and synchronization signal generator 65 are all connected to the computer host 71 via network cables. Before each impact, corresponding software is used to control the oscilloscope 52, high-speed camera 62, and synchronization signal generator 65 to enter a signal waiting state. After each impact, the computer host 71 sends program instructions to the oscilloscope 52 and high-speed camera 62 to save the data.

[0036] This invention relates to a cyclic impact life testing method for filaments used in synchrotron radiation light sources, specifically as follows: Step 1: First, place the square ferromagnetic bullet 46 into the barrel and adjust its position between the one-way valve 31 and the bullet blocking baffle 32. Then, fix one end of the wire sample 18 to the aluminum alloy drive wheel 11 and rotate the aluminum alloy drive wheel 11 to wind the wire sample 18 around it, thus eliminating stress concentration. After completion, fix the aluminum alloy drive wheel 11 to the corresponding optical axis 12. Then fix the other end of the wire sample 18 to another aluminum alloy drive wheel 11 and fix it to the corresponding optical axis 12. Subsequently, rotate the optical axis 12 until the tension of the wire sample 18 is close to the set value, and then fix the optical axis 12 and the optical axis cross clamp 13. Throughout the process, ensure that the wire sample 18 is completely fixed.

[0037] Step 2: Using automation software on the computer host 71, control the corresponding software of the oscilloscope 52, high-speed camera 62, and synchronization signal generator 65 to ensure that the oscilloscope 52, high-speed camera 62, and synchronization signal generator 65 are in standby mode. Subsequently, through the computer host 71, with the help of the prestress controller 23, bullet position controller 35, and electromagnetic drive controller 46, adjust the prestress of the wire sample 18, the initial position of the square ferromagnetic bullet, and the driving current of the copper coil 42, thereby ensuring that the square ferromagnetic bullet impacts the wire sample 18 with the set prestress at the set speed; through the automation software on the computer host 71, control the oscilloscope 52 and high-speed camera 62 to record the high-speed photographic impact image and the waveform of the oscilloscope 52 to the computer host 71.

[0038] Step 3: Repeat step 2, cyclically impacting the wire sample 18 until the wire sample 18 breaks; when the prestress controller 23 detects that the tension is zero, it sends a signal to the computer host 71, and the computer host 71 records and saves the number of impacts and then stops the test.

[0039] The present invention will be further described below with reference to specific embodiments.

[0040] A square ferromagnetic bullet, 26.00 mm in length and weighing 6.10 g, is placed inside a square cannon barrel 41, between a bullet-stopping baffle 32 and a one-way valve 31. The spacing of the horizontal support plates 17 with pulleys is adjusted to 110.00 mm, meaning the effective length of the wire sample 18 is 110.00 mm. A 0.20 mm diameter 71A wire sample 18 is fixed to an aluminum alloy drive wheel 11, wound, and then the optical shaft 12 is rotated until the tension of the wire sample 18 is close to the set value of 22.0 N. The initial position of the square ferromagnetic bullet (305 mm from the bullet-stopping baffle) and the voltage (300.0 V) have been pre-measured to ensure that the velocity of the square ferromagnetic bullet is between 5.75 m / s and 5.85 m / s.

[0041] High-speed photography impact images such as Figure 2 As shown. The oscilloscope 52 measured the light-blocking time as follows. Figure 3 As shown, the shading time is 4.48 ms, from which the velocity can be calculated as 26.00 mm / 4.48 ms = 5.80 m / s. Three wire samples 18 were subjected to repeated impacts, and the number of impacts at breakage was 790, 810, and 802, respectively.

[0042] As an extension, using bullets as the research object, this invention can also be applied to the repeatability testing of electromagnetic railgun velocities. Current electromagnetic railgun repeatability testing either involves manual retrieval of bullets after they miss the target or the use of magazines; the former is extremely inefficient, and the latter cannot guarantee the uniformity of bullet samples. By using flexible wire to deflect the bullet, it is possible to automatically reset the bullet, ensuring that the bullet is undamaged and that its uniformity is guaranteed.

[0043] This invention is simple to operate, safe and reliable, and highly repeatable. It can realize transverse impact cyclic loading of a single filament under different impact velocities and different preloads, and supports in-situ observation of microstructures in conjunction with synchrotron radiation sources, providing an advanced experimental platform for the study of dynamic damage and failure mechanisms of filaments under impact loads.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
