Description

This traditional vacuum tube maglev high-speed rail system has the following key drawbacks:

1. **Instability in guidance**: The train, suspended above the track, faces instability at speeds of thousands of km/h, causing bouncing and swaying, increasing the risk of derailment.

2. **Centrifugal force during high-speed turns**: Large centrifugal forces during turns may lead to tipping or derailment. The pressure exerted on the train, tracks, vacuum tube, and supporting structure increases the risk of fatigue damage.

3. **Large turning radius**: To reduce centrifugal force, the turning radius must be extremely large, sometimes hundreds of kilometers, making it difficult to construct near-straight vacuum tubes between distant cities.

4. **High precision requirements**: To control vibrations at high speeds, the manufacturing and installation of track beams, stator surfaces (fixed tracks), and moving tracks need extremely high precision, which significantly increases costs.

5. **Vacuum sealing and safety**: Maintaining a vacuum in single-layer tubes is challenging, and any damage to the tube could lead to severe accidents.

1. **Guidance Stability**: The high-speed rail system of this invention features three tracks evenly distributed around a circle, spaced 120 degrees apart. The three points define a plane, firmly constraining the train between the tracks, significantly enhancing guidance stability and ensuring the train never derails!

2. **Smaller Turning Radius**: The three fixed tracks collectively provide support and guidance to the train, effectively balancing and dispersing pressures (centrifugal forces) from various directions. This allows the train to stay on track during turns and uphill or downhill movements, resulting in excellent guidance and significantly reducing the turning radius, making it feasible to construct vacuum high-speed rail between any two cities.

3. **Dispersed Centrifugal Forces**: The enormous centrifugal forces generated during high-speed turns are shared by the three tracks, spaced 120 degrees apart. This arrangement evenly distributes the centrifugal forces around the circumference, reducing the impact on the tracks and supporting structures. This greatly mitigates fatigue damage to the components of the vacuum tube superconducting maglev train, lowering safety risks and enhancing the overall safety and comfort of the train.

4. **Reduced Bumpiness and Vibration**: The three tracks evenly distributed around the circumference prevent the train from bouncing upward during ascent or descent, significantly reducing vertical oscillation while also minimizing lateral swaying. When the vacuum tube superconducting maglev train enters and exits stations, the three-wing tracks adapt well to curves and elevation changes.

5. **Segmented Moving Tracks**: The train's moving tracks (dynamic tracks) are segmented rather than continuous, breaking the long track into many shorter segments. This allows for gradual pressure application on the fixed tracks and supporting systems during turns and ascents/descents, reducing the pressure on these components and leading to a smoother ride.

6. **Suspended Structure for Segmented Tracks**: The segmented tracks utilize a suspended structure, further reducing impact.

7. **Dual-Tube Structure**: The outer tube provides support and protection, while the inner tube maintains a vacuum of 1% atmospheric pressure. The inner tube supports the three-wing tracks and operates in a vacuum environment of 0.01% pressure, resulting in minimal aerodynamic drag, allowing the superconducting maglev train to potentially reach speeds of 4000 km/h or higher. The dual-tube structure also facilitates high vacuum maintenance, reducing sealing requirements.

8. **Electromagnetic Propulsion**: This system uses the principle of electromagnetic propulsion to accelerate or decelerate the train. During the initial segment, electromagnetic forces smoothly drive the train forward. The propulsion devices can be flexibly distributed along the starting point, middle, and end of the track as needed. As the train approaches its destination, the same electromagnetic principles are used for reverse braking, ensuring a smooth stop.

9. **Superconducting Magnetic Levitation Tracks**: By utilizing the resistance-free property of superconductors, a strong magnetic field is generated to act on the capsule-like train carriage, providing lift, guidance, and propulsion.

10. **Reduced Manufacturing and Installation Precision**: Traditional trains operating at thousands of kilometers per hour require extremely high precision in the manufacturing and installation of track beams, stator surfaces (fixed tracks), and moving tracks. Such high precision requirements greatly increase production and installation costs. The three-wing tracks of this invention significantly reduce the precision requirements for the stator surfaces and moving tracks, lowering costs and improving economic efficiency.
