Abstract

The invention relates to a three-dimensional measuring device for suspension characteristics of a high-temperature superconducting magnetic suspension bearing. A permanent-magnet rotor fixing device (13) is installed at a sliding block (30) of a vertical mechanical arm (6) of a triaxial movement manipulator; the back surface of the permanent-magnet rotor fixing device (13) is in contact with the upper end surface of the sliding block (30); and the lower end surface of the permanent-magnet rotor fixing device (13) is perpendicular to the upper end surface of the sliding block (30). A double-layer low-temperature Dewar includes a Dewar unit (14) and a Dewar support device; a plurality of force cell sensors are arranged at a peripheral outer wall or bottom surface of the Dewar unit (14); one end of each force cell sensor is connected with the Dewar unit (14) and the other end is fixed at a sensor fixation unit. The sensor fixation unit is arranged at the bottom of the Dewar unit (14) or the peripheral outer wall of the Dewar. A manipulator motion control system is connected with the triaxial movement manipulator. An automatic control system is connected with the force cell sensors and the manipulator motion control system and is also connected with a serial port of an upper computer.

Description

technical field [0001] The invention relates to a device for measuring the suspension characteristics of a high-temperature superconducting magnetic suspension bearing. Background technique [0002] High-temperature superconducting flywheel energy storage systems can be used in key fields such as power storage, electromagnetic ejection, and attitude adjustment of space satellites. High-temperature superconducting magnetic suspension bearings are one of the core components of high-temperature superconducting flywheel energy storage systems. When developing a flywheel energy storage system, it is necessary to conduct detailed research and measurement on the suspension characteristics such as the load capacity and stiffness of the high temperature superconducting magnetic suspension bearing. [0003] The levitation force and stiffness of the high temperature superconducting magnetic suspension bearing are important indicators of the magnetic suspension bearing. The levitation ...
