Description

Technical Field

[0001] The utility model relates to the technical field of mechanical measurement, in particular to a force measuring tool of a magnetic suspension dynamics experimental instrument. Background Art

[0002] In the existing technology, the inclination angle of the guide rail is not enough to enable the maglev vehicle to overcome all resistance and move at a uniform speed, which limits the experimental conditions and makes it impossible to fully study the dynamic characteristics under different motion states.

[0003] The force applied by the compression spring is difficult to control accurately, so the specific force value applied to the trolley cannot be accurately known. Due to the uncertainty of the force, this directly leads to large errors in the experimental results, affecting the accuracy and reliability of the experiment. Utility Model Content

DETAILED DESCRIPTION

[0034] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] like Figures 1 to 3 As shown, the embodiment of the utility model provides a force measuring tool for a magnetic suspension dynamics experiment instrument, comprising:

[0036] Tester body;

[0037] The guide rail 4 is arranged on the tester body;

[0038] The magnetic levitation vehicle is arranged on the guide rail 4 and moves on the guide rail 4;

[0039] Springs 7, arranged at both ends of the tester body, are used to provide power to the magnetic levitation vehicle;

[0040] The magnet 10 is fixed on the magnetic levitation vehicle, and enables the magnetic levitation vehicle to travel on the guide rail 4 through the principle of magnetic repulsion and attraction;

[0041] The push-pull force meter 11 is arranged on one side of the magnetic levitation vehicle and is used to measure and display the magnitude of the force applied to the magnetic levitation vehicle.

[0042] In the embodiment of the utility model, the tester body ensures the stable installation and precise positioning of each component. The guide rail 4 is fixed on the tester body to provide a smooth and limited movement path for the maglev trolley. The maglev trolley is suspended and moves on the guide rail 4 through the magnetic force generated by the magnet 10. The springs 7 are located at both ends of the tester body and are connected to the maglev trolley. When the springs 7 are compressed or stretched, they provide power for the maglev trolley to push or pull the trolley to move on the guide rail 4. The magnet 10 is fixed on the maglev trolley, and the principle of magnetic repulsion and attraction is used to enable the maglev trolley to travel stably on the guide rail. By adjusting the polarity and strength of the magnet 10, the suspension height and movement speed of the trolley on the guide rail 4 can be controlled. The push-pull force gauge 11 is installed on one side of the maglev trolley to monitor and display the magnitude of the force applied to the maglev trolley in real time.

[0043] By using the guide rail 4 and the push-pull force gauge 11, the motion state and force conditions of the magnetic levitation vehicle can be very accurately controlled and recorded, thereby improving the accuracy of the test. Since the entire system is precisely controlled and monitored, the same test conditions can be repeated in order to conduct multiple tests and obtain reliable data. By utilizing the principle of magnetic repulsion and attraction, the direct friction between the vehicle and the guide rail can be reduced, thereby reducing the risk of wear and failure. By adjusting the elastic force of the spring 7 and the strength of the magnet 10, the movement speed and suspension height of the vehicle can be easily adjusted to meet different test requirements. The push-pull force gauge 11 can be used to observe and record the changes in the force of the vehicle during movement in real time, so that researchers can intuitively understand the motion state of the vehicle.

[0044] like Figures 1 to 3 As shown, the tester body includes:

[0045] A bottom plate 1, wherein a guide rail 4 is arranged on the bottom plate 1;

[0046] A protective cover 15 is provided on the bottom plate 1;

[0047] An angle scale 3, one end of which is fixed on the protective cover 15, and the other end is fixed on the bottom plate 15, and is used to measure and display the angle position of the magnetic levitation vehicle;

[0048] Photoelectric gates 5, two of which are installed on the protective cover 15, and are used to detect the uniformly variable linear motion of the magnetic levitation vehicle;

[0049] A support seat 6, disposed on the bottom plate 1 and used to support one end of the bottom plate 1;

[0050] There are two pulleys 12 , which are movably connected to the support seat 6 .

[0051] In an embodiment of the utility model, the base plate 1 provides a stable platform for installing the guide rail 4 and the support seat 6, ensuring the relative position accuracy between the components. The guide rail 4 is installed on the base plate 1 to provide a certain travel path for the maglev vehicle. The protective cover 15 is installed on the base plate 1 to protect the internal components from external interference and damage. At the same time, it also provides an installation position for measuring tools such as the angle scale 3 and the photoelectric gate 5. The angle scale 3, one end of which is fixed to the protective cover 15 and the other end is fixed to the base plate 1, can measure and display the angular position of the maglev vehicle, thereby helping researchers to accurately understand the movement trajectory and posture changes of the vehicle.

[0052] There are two photoelectric gates 5, which are installed on the protective cover 15. When the magnetic levitation vehicle passes through the photoelectric gates 5, they will record the time when the vehicle passes through, thereby helping researchers analyze the uniformly accelerated linear motion characteristics of the vehicle. The support seat 6 is installed at one end of the base plate 1 to support and stabilize the base plate 15. There are two pulleys 12, which are movably connected to the support seat 6, so that the test instrument body can be easily moved and adjusted, improving the portability and flexibility of the equipment.

[0053] The stable design of the base plate 1 and the support seat 6 ensures the stability and rigidity of the tester body, providing reliable hardware support for high-precision tests. The precise measurement function of the angle scale 3 and the photoelectric gate 5 enables researchers to accurately obtain the motion data and performance parameters of the maglev vehicle, thereby conducting more in-depth analysis and research. The design of the pulley 12 improves the convenience of movement and adjustment of the equipment, allowing researchers to easily perform test operations in different environments.

[0054] like Figures 1 to 3 As shown, a support rod 8 is provided on the extension plate of the base plate 1 .

[0055] In the embodiment of the present invention, the support rod 8 is fixed to the extension plate of the base plate 1 to form a stable support structure. This design can enhance the stability of the entire base plate 1 and its experimental instruments.

[0056] like Figures 1 to 3 As shown, the support rod 8 is provided with a handle 2, which is buckled on the support rod 8 by screws.

[0057] In an embodiment of the utility model, the handle 2 is provided with an interface matching the support rod 8, and screws are passed through the reserved holes of the handle 2 and the support rod 8, and then tightened with nuts, thereby ensuring that the handle 2 is stably fixed on the support rod 8. This connection method not only ensures the stability of the handle 2, but also facilitates installation and disassembly. The handle 2 allows the experimenter to better control the magnitude of the force.

[0058] like Figures 1 to 3As shown, the protective cover 15 is connected to the handle 2 on the outside, and the handle 2 penetrates the protective cover 15 and is connected to the spring 7.

[0059] In the embodiment of the utility model, the operator can operate outside the protective cover 15 through the handle 2, and transmit force or control signals through the spring 7. When the handle 2 is operated, the spring 7 will compress or stretch to transmit force to the internal mechanical mechanism. This design combines the protective function of the protective cover 15, the convenience of the operation of the handle 2, and the force transmission of the spring 7, which together improves the safety of the device.

[0060] like Figures 1 to 3 As shown, the magnetic levitation vehicle comprises:

[0061] A vehicle body 9 is arranged on the guide rail 4;

[0062] A button, which has different modes and is arranged on the vehicle body 9, and is used to control the magnetic levitation vehicle;

[0063] There are eight rail wheels 14 , which are arranged on the vehicle body 9 .

[0064] In an embodiment of the utility model, the car body 9 is designed to adapt to the shape and characteristics of the guide rail 4 to ensure that the maglev vehicle can run stably on the guide rail. The buttons installed on the car body 9 provide different operating modes, such as switching, clearing, conversion, etc. The operator sends instructions by pressing different buttons, and these instructions are received and interpreted by the control system inside the car body, thereby changing the operating state of the maglev vehicle. The eight track wheels 14 installed at the bottom of the car body 9 play a key role when the maglev system is not activated or requires auxiliary support. These wheels contact the guide rail 4 when necessary to provide stability and guidance for the maglev vehicle, or assist in movement when running at low speed.

[0065] The magnetic levitation technology enables the vehicle body 9 to run on the guide rail 4, which not only reduces wear and tear, but also improves the smoothness and reliability of operation. Through the buttons on the vehicle body 9, the operator can easily select and control the different operating modes of the magnetic levitation vehicle, making the operation more intuitive and simple. The track wheel 14 provides additional support when the magnetic levitation system fails, preventing the vehicle body from leaving the guide rail, thereby enhancing the safety of operation.

[0066] like Figures 1 to 3 As shown, four rail wheels 14 are respectively arranged on both sides of the vehicle body 9 .

[0067] In the embodiment of the utility model, the four track wheels 14 arranged on each side of the car body 9 play a key role in stability and guidance during the operation of the maglev car. When the maglev car is traveling at a uniform speed on the guide rail 4, these wheels can keep the car body in the correct position on the guide rail to prevent deviation. When traveling at a low speed or parking, the magnetic buoyancy force may not be sufficient to fully support the car body. At this time, the track wheels 14 will contact the guide rail 4 to provide smooth movement for the car body. Through the design of four track wheels on each side of the car body, the maglev car can obtain better stability during operation and reduce the risk of shaking and deviation from the guide rail. The track wheels 14 provide support when necessary, thereby improving the safety of operation. When traveling at a low speed, the assistance of the track wheels can make the maglev car move more smoothly and reduce the instability caused by insufficient magnetic buoyancy.

[0068] The above is a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
