AI Technical Summary
Existing experimental platforms cannot accurately simulate the transient electromagnetic loads of maglev trains based on the principle of electromagnetic levitation, especially maglev trains based on the principle of electric levitation, and traditional wheel-rail train test platforms are not suitable for maglev trains.
A comprehensive electromagnetic vibration test platform was designed, which includes multiple excitation modules. Each module consists of first and second excitation coil layers. By injecting DC and AC currents of different polarities and phases into a single rectangular coil, a fundamental and harmonic spatial magnetic field is constructed to simulate the electromagnetic load of a maglev train.
It can accurately simulate the electromagnetic load and attitude changes of the suspension frame under real motion conditions in an offline state, verify the durability of superconducting magnets, optimize the design of ground propulsion coils, and improve the safety and comfort of trains.
