Description

Technical Field

[0001] This invention relates to the field of aerodynamic testing technology, and in particular to a launching device and its operating method that can quantitatively control translational and rotational speeds. Background Technology

[0002] In physics teaching and research experiments, it is often necessary to study the trajectory of a rotating flying object and the relationship between its initial motion parameters. These initial motion parameters include, but are not limited to, translational velocity, rotational angular velocity, and launch angle. Research experiments typically require single-variable control, necessitating quantitative control of each initial motion parameter.

[0003] Existing launching devices mostly rely on manual operation, making it difficult to achieve quantitative control of parameters and repeatable launches, thus affecting the accuracy and comparability of experimental data. In response, some researchers have proposed using commercially available flight launch devices such as frisbee launchers, which can quantitatively control launch speed and launch angle, thereby meeting the needs of some experimental scenarios.

[0004] However, this type of frisbee launcher also has its limitations. Because it typically uses a rotating wheel drive, when the outer edge of the frisbee contacts the high-speed rotating wheel, the frisbee gains a certain translational speed and rotational angular velocity through friction, causing it to be launched from the launcher. Firstly, this drive method makes the translational speed and rotational angular velocity of the projectile interdependent, making it difficult to quantitatively control either parameter alone, which is not conducive to detailed research experiments. Secondly, this drive method requires the projectile to be disc-shaped; it cannot be used when the projectile is of other shapes (such as a boomerang), further limiting the application scenarios of this type of projectile launcher. Summary of the Invention

[0005] The present invention aims to at least solve one of the aforementioned technical problems existing in the prior art. To this end, this application proposes a launching device that can quantitatively control translational and rotational speeds, capable of quantitatively controlling the translational speed and rotational angular velocity of the launching object, and without limiting the shape of the launching object, thus making it applicable to a variety of experimental scenarios.

[0006] This application also proposes a method for operating the aforementioned launching device with quantitatively controllable translational and rotational speeds.

[0007] A launching device according to a first aspect embodiment of the present application, capable of quantitatively controlling translational and rotational speeds, includes:

[0008] A translation drive system includes a guide rail, a slider, and an elastic element. The slider slides on the guide rail, and the elastic element is detachably connected to the slider and is used to drive the slider to move.

[0009] A rotary drive system includes a rotary platform and a motor, the motor being fixed to the slider, and the rotary platform being connected to the rotary output shaft of the motor;

[0010] A clamping mechanism includes a clamping member and a clamping release device, wherein the clamping member is mounted to the rotating platform and the clamping release device drives the clamping member to open or close;

[0011] The clamping member can clamp the flying component. The moving speed of the flying component can be changed by replacing the elastic member with one that has a different elastic strength. The rotational angular velocity of the flying component can be changed by changing the rotational speed of the motor.

[0012] The launching device according to the embodiments of this application, which can quantitatively control translational and rotational speeds, has at least the following beneficial effects: This launching device independently controls the translational speed of the flight component through a translational drive system and independently controls the rotational angular velocity of the flight component through a rotational drive system, thereby enabling the two speeds to be quantified separately without affecting each other. Furthermore, the drive method of clamping the flight component with a clamping member and driving rotation through a motor eliminates the need to restrict the shape of the flight component, thus providing greater versatility.

[0013] According to some embodiments of this application, the translation drive system further includes a release mechanism that can engage with the slider, and triggering the release mechanism can release the slider.

[0014] According to some embodiments of this application, the release mechanism includes a fixed plate, a first trigger rod, and a first electromagnet. The first trigger rod is hinged to the fixed plate, and the end of the first trigger rod can engage with the slider. The first electromagnet drives the first trigger rod to flip. When the first electromagnet drives the first trigger rod to flip, the end of the first trigger rod disengages from the slider, and the slider is released.

[0015] According to some embodiments of this application, the release mechanism further includes a reset elastic element, the two ends of which are respectively connected to the first trigger rod and the fixed plate. The function of the reset elastic element is to restore the first trigger rod to its initial state.

[0016] According to some embodiments of this application, the translation drive system further includes two speed sensors, which are respectively disposed at both ends of the guide rail. When the slider moves to the position corresponding to the speed sensor, the corresponding speed sensor can be triggered.

[0017] According to some embodiments of this application, the translation drive system further includes a limiting member installed at the end of the guide rail, the limiting member being able to contact the slider to prevent the slider from rushing out of the guide rail.

[0018] According to some embodiments of this application, the limiting member includes a buffer elastic member, which is capable of directly contacting the slider and converting the slider's kinetic energy into elastic potential energy.

[0019] According to some embodiments of this application, the rotary drive system further includes a counterweight block, which is detachably mounted on the rotary platform and is used to adjust the dynamic balance of the rotary platform.

[0020] According to some embodiments of this application, the clamping release device includes a second trigger rod and a second electromagnet. The second trigger rod is hinged to the rotating platform. One end of the second trigger rod contacts the clamping member, and the other end of the second trigger rod contacts the output end of the second electromagnet. The output end of the second electromagnet can be displaced along its axial direction, thereby triggering the clamping member through the second trigger rod.

[0021] The working method according to the second aspect of this application, which is based on the above-described launching device capable of quantitatively controlling translational and rotational speeds, includes the following steps:

[0022] Select the elastic element and connect it to the slider so that the elastic element stores elastic potential energy.

[0023] The flight component to be tested is mounted onto the clamping component;

[0024] Set the rotational speed of the motor in preparation for the launch experiment;

[0025] The motor is turned on, and the rotating platform drives the flying component to rotate.

[0026] Once the flying component reaches the set angular velocity requirement, the slider is released;

[0027] The elastic potential energy in the elastic element is converted into the kinetic energy of the slider, and the slider moves rapidly along the guide rail;

[0028] The clamping release device is triggered during the translation of the slider, causing the clamping member to release the flying component;

[0029] The flying component flies out of the clamping component with a set translational speed and rotational angular velocity.

[0030] The working method according to the embodiments of this application has at least the following beneficial effects: by selecting a suitable elastic element, the translational speed of the flying component can be changed, and by adjusting the rotational speed of the motor, the rotational angular velocity of the flying component can be changed, thereby enabling individual control of the translational speed and rotational angular velocity of the flying component.

[0044] In physics teaching and research experiments, it is often necessary to study the trajectory of a rotating flying object and the relationship between its initial motion parameters. These initial motion parameters include, but are not limited to, translational velocity, rotational angular velocity, and launch angle. Research experiments typically require single-variable control, necessitating quantitative control of each initial motion parameter.

[0045] Existing launching devices mostly rely on manual operation, making it difficult to achieve quantitative control of parameters and repeatable launches, thus affecting the accuracy and comparability of experimental data. In response, some researchers have proposed using commercially available flight launch devices such as frisbee launchers, which can quantitatively control launch speed and launch angle, thereby meeting the needs of some experimental scenarios.

[0046] However, this type of frisbee launcher also has its limitations. Because it typically uses a rotating wheel drive, when the outer edge of the frisbee contacts the high-speed rotating wheel, the frisbee gains a certain translational speed and rotational angular velocity through friction, causing it to be launched from the launcher. Firstly, this drive method makes the translational speed and rotational angular velocity of the projectile interdependent, making it difficult to quantitatively control either parameter alone, which is not conducive to detailed research experiments. Secondly, this drive method requires the projectile to be disc-shaped; it cannot be used when the projectile is of other shapes (such as a boomerang), further limiting the application scenarios of this type of projectile launcher.

[0047] In response, this application proposes a launching device that can quantitatively control translational and rotational speeds. It independently controls the translational speed of the launcher through a translational drive system and independently controls the rotational angular velocity of the launcher through a rotational drive system, thus allowing the two speeds to be quantified separately without interfering with each other. Furthermore, the drive method, which uses a clamping device to hold the launcher and a motor to drive its rotation, eliminates restrictions on the shape of the launcher, thereby achieving greater versatility.

[0048] In addition, this application also proposes a working method for the above-mentioned launch device with quantitatively controllable translational and rotational speeds. By selecting a suitable elastic element, the translational speed of the flight component can be changed, and by adjusting the speed of the motor, the rotational angular velocity of the flight component can be changed, thereby enabling individual control of the translational speed and rotational angular velocity of the flight component.

[0049] Reference Figure 1 and Figure 2 The launching device with quantitatively controllable translational and rotational speeds according to the first aspect of this application includes a translational drive system 100, a rotational drive system 200, and a clamping mechanism 300. The translational drive system 100 drives the flight component to translate; the rotational drive system 200 drives the flight component to rotate; and the clamping mechanism 300 clamps the flight component and releases it promptly after it reaches a preset initial translational velocity and rotational angular velocity, thus launching the flight component. Since the translational drive system 100 and the rotational drive system 200 operate independently, the initial translational velocity and rotational angular velocity of the flight component can be controlled separately, avoiding mutual interference. Furthermore, using the clamping mechanism 300 to clamp the flight component does not impose any requirements on the shape of the flight component, allowing for experiments with a wider variety of flight components.

[0050] Specifically, the translation drive system 100 includes a guide rail 110, a slider 120, and an elastic element 130. The slider 120 slides on the guide rail 110, and the elastic element 130 is detachably connected to the slider 120 and is used to drive the slider 120 to move. It is worth noting that the elastic element 130 can be replaced, thereby allowing the movement speed of the slider 120 to be adjusted by replacing the elastic element 130 with one of different elastic strengths.

[0051] Reference Figure 4 and Figure 5 The rotary drive system 200 includes a rotary platform 210 and a motor 220. The motor 220 is fixed to the slider 120, and the rotary platform 210 is connected to the rotary output shaft of the motor 220, so that the rotary platform 210 can rotate under the drive of the motor 220. The rotational angular velocity of the rotary platform 210 can be adjusted by adjusting the output power of the motor 220.

[0052] The clamping mechanism 300 includes a clamping member 310 and a clamping release device 320. The clamping member 310 is mounted to the rotating platform 210, and the clamping release device 320 drives the clamping member 310 to open or close. The clamping member 310 is capable of clamping a flying component. After the rotating platform 210 rotates under the drive of the motor 220, it can drive the flying component clamped by the clamping member 310 to rotate synchronously. When the clamping release device 320 drives the clamping member 310 to open, the flying component can rotate and fly outwards.

[0053] Furthermore, referring to Figure 3 The translation drive system 100 also includes a release mechanism 140, which can engage with the slider 120. Triggering the release mechanism 140 can release the slider 120, so that the slider 120 can move along the guide rail 110 under the drive of the elastic member 130.

[0054] The specific structure of the release mechanism 140 includes a fixed plate 141, a first trigger rod 142, and a first electromagnet 143. The first trigger rod 142 is hinged to the fixed plate 141, and its end can engage with the slider 120. The first electromagnet 143 drives the first trigger rod 142 to rotate. Specifically, the first electromagnet 143 has an output end that can extend and retract along its axial direction. This output end contacts the first trigger rod 142, and when the output end extends and retracts, it can drive the first trigger rod 142 to rotate. Thus, when the first electromagnet 143 drives the first trigger rod 142 to rotate, the end of the first trigger rod 142 disengages from the slider 120, and the slider 120 is released.

[0055] Optionally, the release mechanism 140 further includes a reset elastic element 144, the two ends of which are connected to the first trigger rod 142 and the fixing plate 141 respectively. The function of the reset elastic element 144 is to restore the first trigger rod 142 to its initial state.

[0056] Furthermore, the translation drive system 100 also includes two speed sensors 150, which are respectively disposed at both ends of the guide rail 110. When the slider 120 moves to the position corresponding to the speed sensor 150, it can trigger the corresponding speed sensor 150. Thus, during the process of the slider 120 being driven by the elastic element 130, the slider 120 will trigger the two speed sensors 150 successively, thereby obtaining the time taken for the slider 120 to pass between the two speed sensors 150. The movement speed of the slider 120 can be obtained by dividing the distance between the two speed sensors 150 by the time the slider 120 moves between the two speed sensors 150.

[0057] The specific structure of the speed sensor 150 can be a photoelectric gate sensor, a contact sensor, or an acoustic ranging sensor, which will not be elaborated here.

[0058] Optionally, the translation drive system 100 further includes a limiting member 160, which is installed at the end of the guide rail 110. The limiting member 160 can contact the slider 120 to prevent the slider 120 from rushing out of the guide rail 110. Further, the limiting member 160 includes a buffer elastic member 161, which is elastic. The buffer elastic member 161 can directly contact the slider 120 and convert the kinetic energy of the slider 120 into elastic potential energy, thereby playing a buffering and energy-absorbing role and reducing the damage caused to the limiting member 160 by the impact of the slider 120.

[0059] Furthermore, the rotary drive system 200 also includes a counterweight 230, which is detachably mounted on the rotary platform 210. The counterweight 230 is used to adjust the dynamic balance of the rotary platform 210, so that after the clamping mechanism 300 clamps the flying part, the center of gravity of the whole composed of the components on the rotary platform 210 is maintained on the rotation axis of the rotary platform 210, thus avoiding large shaking during rotation due to dynamic imbalance.

[0060] It is easy to understand that the counterweight 230 can be replaced, and the dynamic balance of the rotating platform 210 can be changed by changing the counterweight 230 of different weights.

[0061] Specifically, the clamping release device 320 includes a second trigger rod 321 and a second electromagnet 322. The second trigger rod 321 is hinged to the rotating platform 210. One end of the second trigger rod 321 contacts the clamping member 310, and the other end of the second trigger rod 321 contacts the output end of the second electromagnet 322. The output end of the second electromagnet 322 can be displaced along its axial direction, thereby triggering the clamping member 310 through the second trigger rod 321.

[0062] The working method in the second aspect embodiment of this application, based on the above-mentioned launching device capable of quantitatively controlling translational and rotational speeds, includes the following steps:

[0063] S100. Select the elastic element 130 and connect it to the slider 120 so that the elastic element 130 stores elastic potential energy.

[0064] S200. Mount the flight component to be tested onto the clamping component 310;

[0065] S300. Set the speed of motor 220 to prepare for the launch experiment;

[0066] S400. Start motor 220, and rotating platform 210 drives the flying component to rotate;

[0067] S500. Once the flying component reaches the set angular velocity requirement, release slider 120;

[0068] S600. The elastic potential energy in the elastic element 130 is converted into the kinetic energy of the slider 120, and the slider 120 moves rapidly along the guide rail 110;

[0069] S700. The clamping release device 320 is triggered during the translation of the slider 120, causing the clamping member 310 to release the flying part;

[0070] S800. The flying component flies out of the clamp 310 with a set translational speed and rotational angular velocity, completing the launch operation of the flying component.

[0071] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
