Problems solved by technology

The test device can test the vertical force and the guiding force separately and independently, and it is impossible to test the vertical force (suspension force) and the guiding force at the same time; The levitation force or guiding force between the permanent magnet track and the block above it, but the levitation force or guiding force between the block and the magnet above it cannot be tested, so its test application field is limited
During the test, it is driven to the designated position first, and then the test data is collected at one time, which cannot realize continuous testing
It is also impossible to test the relationship between guiding force, suspension force and time (that is, force relaxation)
It is even more impossible to realize the automatic test of magnetic stiffness
The entire test device is driven by two axes, which cannot realize fully automatic three-dimensional positioning and movement
The testing process is cumbersome
In particular, the horizontal alignment of the permanent magnet track and the block requires manual movement, which is very difficult or even impossible

Description

technical field [0001] The invention relates to the technical field of high-temperature superconducting magnetic levitation testing. Background technique [0002] The research on high-temperature superconducting maglev trains is still in its infancy. Most of the research that has been done is on the high-temperature superconductor block itself and the study on the magnetic levitation force of a single block to improve material performance. For the research on the performance of high-temperature superconducting bulk materials on high-temperature superconducting maglev trains, there are still many problems that have not been studied due to the limitation of experimental research methods. Existing high-temperature superconducting maglev testing, such as the applicant's No. 99117455.0 patent "High-temperature superconducting maglev testing method", is to suspend the superconducting block in the center under the bracket, and pass a Dimensional horizontal locator to place the per...
