| 摘 要： | 根据一种差动式变压器结构的磁性液体倾斜角传感器工作原理,推导出传感器输出电压与灵敏度公式,并利用ANSYS软件对这种结构的传感器进行电磁-电路的耦合场分析,通过对数值模拟结果进行深入分析以便能为传感器的设计提供指导,并将模拟结果与已公开发表的实验数据进行对比.得出当磁性液体倾斜角传感器的结构参数确定后,传感器的输出电压与转动角度成线性正比关系;且传感器的灵敏度与激励电压的振幅、磁性液体相对磁导率及激励电压频率成正比,但激励电压频率超过一定范围后,传感器灵敏度增加值会逐渐减小,建议激励电压频率最好不超过1.5 kHz.

| Abstract: | The paper presents a tilt sensor with magnetic fluid,which is dedicated to measure small inclination angles with respect to a horizontal or vertical plane.The operating principle of the sensor is introduced;the formulas of the output voltage and sensitivity are deduced.Based on the finite element software ANSYS,the magnetic circuit coupling field of the sensor is analyzed.Numerical simulation results show that the output voltage of the sensor has a linear relationship with the inclination angle.The factors ... |
