摘要

为设计新型的小型高精度磁悬浮式加速度计,利用仿真软件对自制超顺磁性加速度计悬浮体在外磁场中所受的磁力进行仿真,并通过悬浮实验测试超顺磁性加速度计悬浮体在常温常压下的悬浮性能.仿真结果表明:超顺磁性加速度计悬浮体在外磁场中所受的磁力完全受外磁场控制.悬浮实验表明:当外磁场强度合适时,超顺磁性加速度计悬浮体可在常温常压下实现悬浮.实验表明:新型超顺磁性加速度计悬浮体适用于设计小型高精度磁悬浮式加速度计.%To design new type of small size high precision magnetic levitation accelerometer, the magnetic force of self-made superparamagnetic levitalion object of accelerometer in external magnetic field is simulated by software, and the levitation properties of superparamagnetic levitation object by accelerometer is test by levitation experiments. Simulation results demonstrate that the superparamagnetic leritation object of accelerometer is fully controlled by external magnetic field. Levitation experiments indicate that the superparamagnetic levitation object of accelerometer can be levitated under normal temperature and pressure. Experimental results show that this superparamagnetic levitation object of accelerometer is suitable for designing small size high precision magnetic levitation accelerometer.
