The face performance of axis is poor.Mutually exclusive due to the magnetic line of force by taking common tracks of permanent magnetism as an example, rail superior portion space magnetic field can be with
Two magnetic-field components (Bz and Bx) of z-axis and x-axis direction are decomposed into, and the peak value of the two is not overlapped.Thus, fully horizontally arrange
Mode will make it is in running order with the face containing c-axis in the hts bulk of Bx larger part.And for fully horizontally arranging
Band for, the repulsive interaction due to superconducting layer to the magnetic line of force will be more towards the gold from band in the magnetic field of Bx larger part
Belong to and passing through in base band, so that superconductor cannot fully demonstrate out to the pinning effect of magnetic flux.And guiding force is mainly logical
Flux pinning force pinning flux quantum is crossed to maintain the rigidity and stability of guiding, therefore fully horizontal arrangement will lead to
Levitation vehicle high-speed cruising or the stability of turning are poor.High-temperature superconductor band be using the face lattice ab as working face, it is big in Bz
Place is placed using positive, and Bx big place, which is taken, to be laterally located, and is for so that the face lattice ab is sufficiently made with magnetic field
With to obtain the suspending power and guiding force of optimization.Thus the high-temperature superconductor band stackable unit that uses of the present invention can be
The stability of raising guiding while sufficiently increasing suspending power, wherein the positive of high-temperature superconductor band places main offer suspension
Power is laterally located main offer guiding force, has greatly played the advantage of high-temperature superconductor band.
2. high-temperature superconductor band has higher at Xiang Zhiliang, higher magnetic flux nail compared to conventional high-temperature superconduction block material
Bundle ability, to have higher critical current density.This makes it resist the flux quantum disengaging superconduction that alternating magnetic field induces
The ability of body enhances, to reduce A.C.power loss；Simultaneously as the capacity of heat transmission of the nickel based metal base band of band is preferable, from
And local heating's phenomenon caused by causing magnetic pain to be jumped because of thermal agitation can be inhibited, reduce the energy loss therefore generated.
3. the eddy current effect that the metallic nickel base of high-temperature superconductor band generates can play the effect of damping shock absorption simultaneously, simultaneously
Magnetic suspension gap will not be reduced, reduce the influence to traffic safety.
It to sum up, can be according to requiring to cut out the geometric form for being stacked into needs due to the geometry ductility of high-temperature superconductor band
Shape makes full use of the distribution mode in magnetic field to greatest extent.It is compared to the suspended pattern of high-temperature superconducting block composition, high-temperature superconductor
Band is much better than high-temperature superconducting block at phase quality, thus can obtain preferably suspension and steering capability.For tracks of permanent magnetism
Spatial magnetic field state, the first high-temperature superconductor band unit that Bz component peak region position arrangement forward direction is arranged in magnetic field
Box, and the second high-temperature superconductor band unit box of lateral arrangement is arranged in Bx component peak region, realize the magnetic of magnetic floating system
Buoyancy and guiding force are distributed rationally.
