超导空心球形转子的非球形误差将产生干扰力矩、引起漂移误差降低仪表精度。针对转速和温度引起超导空心球形转子的非球形误差进行分析,将超导空心球形转子模型直接从CREO中导入到有限元分析软件ANSYS,并对超导空心球形转子进行有限元变形仿真。通过对仿真结果进行分析,得出超导空心球形转子离心变形量和温度变形量,阐明了超导空心球形转子特有的变形规律,为补偿和减小转子的动态变形提供了理论依据,也为该特殊结构的空心薄壁转子的设计和优化提供了重要依据。
Non-spherical superconducting hollow spherical rotor error will produce interference torque, causing drift error to reduce instrument accuracy. Aiming at the non-spherical error of superconducting hollow spherical rotor caused by rotating speed and temperature, the superconductive hollow spherical rotor model was directly imported from CREO to ANSYS. The finite element deformation simulation of superconducting hollow spherical rotor was carried out. Through the analysis of the simulation results, the centrifugal deformation and temperature deformation of hollow superconducting hollow spherical rotor are obtained. The deformation rules of superconductive hollow spherical rotor are clarified, which provide the theoretical basis for compensating and reducing the dynamic deformation of the rotor. The design and optimization of this special structure hollow thin-walled rotor provide an important basis.
