磁流体惯性传感中二阶浮力试验因素分析

Factors Analysis of Magnetic Fluid Inertial Sensor in the Second-order Buoyancy

阐述基于磁流体新材料惯性传感器的基本工作原理,二阶浮力是传感器正常工作的前提,提出活动磁块受力模型。基于此模型,分析影响二阶浮力的主要因素:活动磁块材料、活动磁块尺寸、磁流体及温度,为二阶浮力试验提供理论支持。

Working principle of the inertial sensor basing on a new kind material of magnetic fluid is illustrated, pointing out that the second-order buoyancy is the premise of its normal working and also brings forward the force mode of the magnet immersing in the magnetic fluid. Basing on the model, factors influencing the second-order buoyancy are analyzed qualitatively, which are magnetic fluid, environment temperature and magnet including its material and size. It provides the theoretic guide for the second-order buoyancy experiment.
