Description

Technical Field

[0001] The present invention relates to the technical field of structural impact dynamics tests, and particularly relates to an intelligent control device and method for the launch speed of an electromagnetic coil gun. Background Art

[0002] High-speed impact of projectiles is the key to studying high-speed collision dynamics problems. How to effectively increase and precisely control the impact speed of projectiles is the core of high-speed collision experiments. Currently, the commonly used projectile acceleration methods include explosive loading drive and light gas gun loading drive. Due to explosive control reasons, explosive loading drive has gradually been replaced by light gas gun loading drive. Light gas gun loading uses compressed light gas to drive the projectile to accelerate. The loading devices generally have characteristics such as large floor area and poor speed stability. In recent years, electromagnetic drive loading has been used to accelerate projectiles because it can control the stability of the launch speed. Electromagnetic drive loading is further divided into two methods: electromagnetic rail gun loading and electromagnetic coil gun loading. The launch speed of an electromagnetic rail gun depends on the energy of the power supply. When the launch speed reaches kilometers per second, the volume of the power supply will exceed 100 cubic meters, the portability of the equipment is poor, and the electromagnetic radiation intensity of the high-energy power supply is high, seriously affecting the light source detection test equipment. The electromagnetic rail gun cannot be combined with the light source detection test station. Therefore, the technical route of using electromagnetic rail gun loading technology to in-situ study high-speed collision dynamics problems is not mature. The electromagnetic coil gun uses multiple coils to gradually accelerate the projectile until the required test speed is reached. Each coil requires a small amount of power supply energy, the volume of the power supply is small, the portability of the entire equipment is high, and the electromagnetic radiation intensity is low, and it can be directly applied to the light source detection test station. However, the electromagnetic coil gun has extremely high requirements for the discharge timing sequence of each stage of the coil. If the discharge time window of each stage of the coil does not match the projectile acceleration time window, not only will there be no acceleration effect, but instead, an electromagnetic counter-tension will be generated on the projectile, even decelerating the projectile, and the launch speed of the projectile is low, not meeting the high-speed impact requirements of the experiment.

[0003] In summary, due to the lack of effective control technology, the electromagnetic coil gun cannot accurately control the discharge time nodes of each stage of the coil, severely restricting the projectile acceleration effect and unable to achieve higher and more accurate impact speeds. Therefore, developing the intelligent control technology of the electromagnetic coil gun and effectively increasing and precisely controlling the impact speed of the launched projectile is still an urgent problem to be solved in the field of electromagnetic coil gun-driven projectile loading.

[0038] Specific installation process of the intelligent control device for the launch speed of the electromagnetic coil gun of the present invention:

[0039] (1) According to the mass and launch speed of the designed magnetic bullet 2, calculate the number of copper coils 3 required, and arrange the barrel 1, copper coils 3, and diodes 4 according to the Figure 1 layout method. Wind the copper coils 3 around the barrel 1 at a certain distance, and connect the two ends of each copper coil 3 to the two ends of the diode 4 respectively;

[0040] (2) Install the laser speed measurement module 5. At the right end position of each copper coil 3, use a drill to machine a round hole on the barrel 1, and arrange the laser speed measurement module 5 perpendicular to the axis of the barrel 1 at the position of the round hole to ensure that the signal of the laser speed measurement module 5 can pass through the round hole smoothly, and connect the laser speed measurement control port to the laser speed measurement controller 9 with a signal wire;

[0041] (3) Install the electric control switch 8. Connect one end of the electric control switch 8 to the copper coil 3 with a wire and the other end to the positive electrode of the automatic regulating capacitor 6, and connect the control port of the electric control switch 8 to the electric control switch controller 10 with a signal wire;

[0042] (4) Install the automatic regulating capacitor 6. Connect one end of the automatic regulating capacitor 6 to one end of the electric control switch 8 with a wire and the other end to the positive electrode of the diode 4, and connect the control port of the automatic regulating capacitor 6 to the capacitance controller 11 with a signal wire;

[0043] (5) Install the intelligent transformer 7. Connect the positive electrode of the intelligent transformer 7 to the positive electrode of the automatic regulating capacitor 6 and the negative electrode of the intelligent transformer 7 to the negative electrode of the automatic regulating capacitor 6 with wires, and connect the control port of the intelligent transformer 7 to the intelligent transformer controller 12 with a signal wire;

[0044] (6) Install the computer main unit 13 and connect the four ports of the computer main unit 13 to the ports of the laser speed measurement controller 9, the electric control switch controller 10, the capacitance controller 11, and the intelligent transformer controller 12 respectively with signal wires;

[0045] (7) Place the magnetic bullet 2 used in the impact experiment on the electronic scale for weighing, and collect it after weighing for subsequent experiments;

[0046] (8) Input the speed required for the impact experiment into the computer main unit 13. The computer main unit 13 automatically outputs the charging voltage level of each automatically adjustable capacitor 6, the capacitance size of each automatically adjustable capacitor 6, and the on-time of each electric control switch 8. The computer main unit 13 sends the charging voltage level of each capacitor to the intelligent transformer controller 12 through the signal wire, sends the capacitance size of each automatically adjustable capacitor 6 to the capacitance controller 11, and sends the on-time of each electric control switch 8 to the electric control switch controller 10;

[0047] (9) After receiving the capacitance size signal of each automatically adjustable capacitor 6, the capacitance controller 11 adjusts the capacitance of each automatically adjustable capacitor 6 through the control signal wire until the capacitance of each automatically adjustable capacitor 6 reaches the required size;

[0048] (10) After receiving the charging voltage level signal of each one, the intelligent transformer controller 12 adjusts each intelligent transformer 7 through the control signal wire until each intelligent transformer 7 reaches the required voltage size;

[0049] (11) Place the magnetic bullet 2 at the left end of the gun barrel 1 and use the computer main unit 13 to send a signal to charge each automatically adjustable capacitor 6;

[0050] (12) Use the computer main unit 13 to send a signal to turn on each electric control switch 8 in sequence. Each copper coil 3 discharges in sequence to generate an electromagnetic field. Under the action of the electromagnetic force, the magnetic bullet 2 is accelerated once every time it passes through a copper coil 3 (as Figure 2 shown), and at the same time, the laser speed measurement module 5 records the speed of the magnetic bullet 2 at this position;

[0051] (13) The speed recorded by the laser speed measurement module 5 is sent to the computer main unit 13 through the laser speed measurement controller 9, and the computer main unit 13 outputs the speed of the magnetic bullet 2 emitted from the right end of the gun barrel 1;

[0052] (14) If the error between the speed of the magnetic bullet 2 output by the computer main unit 13 and the set impact experiment speed is within 1%, save all the control parameters for subsequent impact experiments;

[0054] (16) Repeat steps (11) to (15) until the magnetic bullet 2 reaches the speed required for the impact experiment.

[0055] Embodiment

[0056] The mass of the shell in this embodiment is in the order of 1 gram to 10 grams, and the launch speed is between 50 m / s and 70 m / s.

[0057] According to the above impact experiment technical parameters, the required number of copper coils 3 is calculated to be 5, and the gun barrel 1, copper coils 3, and diodes 4 are arranged according to the Figure 1 arrangement method. The copper coils 3 are wound around the gun barrel 1 at a certain distance, and the two ends of the copper coils 3 are respectively connected to the two ends of the diode 4.

[0058] According to the above steps (1) to (6), the experimental platform of this embodiment is built to provide a test platform for subsequent impact experiments.

[0059] A steel cylinder with a diameter of 6 mm and a length of 24.5 mm is placed on an electronic scale and weighed to be 5.386 grams. The cylindrical sample after weighing is collected for subsequent tests.

[0060] The impact speed of 61 m / s required for the impact experiment is input to the computer mainframe 13, and the computer mainframe 13 automatically outputs the following results: the charging voltages of the first to fifth automatic adjustment capacitors 6 are all 400 V, the capacitance values of the first to fifth automatic adjustment capacitors 6 are all 3000 μF, the on-time of the first electronic control switch 8 is 0 ms, the on-time of the second electronic control switch 8 is 1.931 ms, the on-time of the third electronic control switch 8 is 3.159 ms, the on-time of the fourth electronic control switch 8 is 4.079 ms, and the on-time of the fifth electronic control switch 8 is 4.723 ms.

[0061] The computer mainframe 13 sends the above parameters to the intelligent transformer controller 12, capacitance controller 11, and electronic control switch controller 10 through the signal line. After receiving the above signals, the capacitance controller 11 and the intelligent transformer controller 12 adjust the capacitance values of the first to fifth automatic adjustment capacitors 6 to be all 3000 μF, and adjust the output voltages of the first to fifth intelligent transformers 7 to be all 400 V.

[0062] Place the magnetic bullet 2 at the left end of the gun barrel 1. Use the computer mainframe 13 to send a signal to charge the first to fifth automatic adjustment capacitors 6 at a voltage of 400V.

[0063] Under the parameter control at the moment when the first to fifth electronic control switches 8 are turned on, sequentially turn on the first to fifth electronic control switches 8. Each copper coil 3 discharges in sequence to generate an electromagnetic field. Under the action of the electromagnetic force, the magnetic bullet 2 passes through 5 copper coils 3, achieving 5 times of acceleration.

[0064] The laser speed measurement module 5 automatically records the speed of the magnetic bullet 2 after each acceleration: the speed after the first acceleration is 24.03 m / s, the speed after the second acceleration is 40.09 m / s, the speed after the third acceleration is 49.33 m / s, the speed after the fourth acceleration is 57.94 m / s, and the speed after the fifth acceleration is 64.17 m / s.

[0065] The speed recorded by the laser speed measurement module 5 is sent to the computer mainframe 13 through the laser speed measurement controller 9. The computer mainframe 13 outputs the final speed of the magnetic bullet 2 fired from the right end of the gun barrel 1 as 64.17 m / s, which differs from the required impact speed of 61 m / s by 3.17 m / s, and the error reaches 5.2%.

[0066] Since the error exceeds 1%, it is necessary to fine-tune the on-time of each electronic control switch 8. Based on the speed of the magnetic bullet 2 recorded by each laser speed measurement module 5 and using the distance between adjacent two copper coils 3, the computer mainframe 13 calculates the new on-time of the electronic control switch 8: the on-time of the first electronic control switch 8 is 0 ms, the on-time of the second electronic control switch 8 is 2.1 ms, the on-time of the third electronic control switch 8 is 3.45 ms, the on-time of the fourth electronic control switch 8 is 4.49 ms, and the on-time of the fifth electronic control switch 8 is 5.12 ms. Then output these on-times to the electronic control switch controller 10 through the signal line.

[0067] Under the control of the on-time of the first to fifth electronic control switches 8 after fine-tuning, sequentially turn on the first to fifth electronic control switches 8. The laser speed measurement module 5 automatically records the speed of the magnetic bullet 2 after each acceleration: the speed after the first acceleration is 24.03 m / s, the speed after the second acceleration is 36.5 m / s, the speed after the third acceleration is 47.11 m / s, the speed after the fourth acceleration is 54.44 m / s, and the speed after the fifth acceleration is 61.25 m / s.

[0068] The speed recorded by the laser speed measurement module 5 is sent to the computer mainframe 13 through the laser speed measurement controller 9. The computer mainframe 13 outputs that the final speed of the magnetic bullet 2 fired from the right end of the gun barrel 1 is 61.25 m / s, with a difference of 0.25 m / s from the required impact speed of 61 m / s in the experiment, and the error reaches 0.4%, which is lower than the error requirement of 1%. All control parameters are saved for subsequent impact experiments.

[0069] The present invention is convenient for loading and unloading, precisely controllable, intelligent in operation, safe and reliable, and can automatically adjust to accelerate the projectile to the order of kilometers per second intelligently, laying an experimental foundation for the research on high-speed collision dynamics problems.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
