Abstract: A cryostat device for a superconducting magnetic levitation train includes a conduction assembly, a support assembly and a refrigeration assembly. The conduction assembly includes a conduction shell, a copper box arranged in the conduction shell, and a thermally-conductive support rod assembly. A top of the thermally-conductive support rod assembly is connected with a bottom of the copper box. A bottom of the thermally-conductive support rod assembly is connected with a bottom wall of the conduction shell. A top of the copper box is provided with a superconducting bulk accommodating cavity. The bottom of the copper box is provided with a cooling energy connecting end. A top of the support assembly is configured to support the conduction assembly. A bottom of the support assembly is connected with a bogie chassis. The refrigeration assembly is provided with a cooling energy input end connected with the cooling energy connecting end.

Abstract: A high-temperature superconducting (HTS) magnetic levitation (maglev) Dewar capable of increasing damping and levitation force and a width calculation method thereof. The HTS maglev Dewar includes an outer container and an inner container. The outer container is fixedly connected to the inner container through a connecting column. The inner container has a cavity configured to accommodate liquid nitrogen. A bottom of the inner container is provided with a bulk superconductor. The inner container is communicated with outside through a liquid nitrogen feeding pipe. The outer container is made of an electrically conductive material.
