摘　　要：高温超导磁悬浮因其独特的无源自稳定优势,在高速轴承、轨道交通和飞轮储能系统等领域有着广阔的应用前景。为了探究高温超导磁悬浮系统的悬浮特性,设计了一种适用于测量磁悬浮轴承悬浮特性的高温超导磁悬浮力三维测量系统。首先,基于伺服驱控的三轴联动直线模组与三轴力传感测量单元设计了测量系统硬件部分,利用LabVIEW设计了数据采集单元,以实现数据连续采样及其图像化。其次,在恒载和永磁悬浮系统下,对高温超导磁悬浮力三维测量系统的测量精度进行校验。最后,建立了超导体-永磁悬浮系统有限元模型,仿真并测量了高温超导体在零场冷和场冷条件下的悬浮力特性,仿真与测量结果保持基本一致。结果表明,该测量系统具有测量精度高(0.5%),三维空间定位准确(±0.02 mm),被测对象相对运动时三轴力同步测量(最大悬浮力500 N,导向力200 N)等特点。With the unique advantage of passive and self-stability levitation,high-temperature superconducting maglev is regarded as a promising element for a wide range of applications such as high-speed bearings,flywheel energy storage system and rail transportation.In order to investigate the levitation behavior of high-temperature superconducting maglev system,a high-temperature superconducting maglev force three-dimensional measurement system is developed,which is suitable for measuring the levitation behavior of maglev bearings.Firstly,based on the triaxial linear module with servo control and triaxial force sensor measurement unit,the hardware of measurement system is designed.Also,the data acquisition unit is developed in LabVIEW so as to realize the continuous sampling and imaging of data.Secondly,the measurement precision of high-temperature superconducting maglev force three-dimensional measurement system is validated under the constant load and permanent magnet levitation system.Finally,a finite element model of the superconductor-permanent magnet levitation system is established.Then,the levitation force behaviors of high-temperature superconductor were simulated and measured under field cooling and zero field cooling conditions.The comparison of the simulation data with the measured data shows that a well agreement between the two can be achieved.The results show that this measurement system has the characteristics of high measurement precision(0.5%),high location accuracy in three-dimensional space(±0.02 mm)and synchronous measurement of three-dimensional force(maximum levitation force 500 N,guidance force 200 N)at movement of the measured specimens.
