In the test of existing superconductor, for the mechanical meaurement of the single stress of superconductor, experimental provision research is more.But, during the superconducting magnet operation, being in usually in the strong-electromagnetic field environment of variation, the strong-electromagnetic field of variation will inevitably bring powerful Lorentz force effect, and this Lorentz force acts on all directions of superconductor.Therefore, under low temperature environment, accurately simulating the combination stressed situation of superconductor, set up the drop-down press-bending experimental provision of low temperature, is another key issue of test macro.
Performance test for superconductor relates to the test such as mechanics, calorifics, electromagnetic property; In existing test macro; More for superconductor Experimental Device of performance test aspect above three; And less for the experimental provision development of the electromagnetic force thermal coupling performance of investigating superconductor, be the hot issue of current engineering circle and academia and investigate superconductor low temperature environment multiple physical field coupling effect down, how under low/varying temperature environment; Superconductor to having heavy current carries out mechanical test, also is the critical problem that this test macro is considered thereby reach Li-Re-many coupling measurements of electricity.
