| 摘 要： | 扭矩传感器是汽车电动助力转向系统（EPS）中的核心部件，根据电磁感应原理设计了一种新型立体磁电式扭矩传感器，首先介绍了传感器的圆柱式结构及工作原理，然后采用Ansoft Maxwell对传感器的电磁感应系统进行建模，通过静态分析，得到在使用电流为100 mA时系统磁场分布状态及静态输出电压，并利用瞬态模块模拟传感器工作过程，得到其动态输出信号为幅值随系统相对位置做呈正弦变化的高频感生电压，最后根据输出信号的特点设计了相应加法检波处理的原理电路。

| Abstract: | Torque sensor is a core member of automotive electric power steering system (EPS), a new three dimensional magnetoelectric torque sensor based on electromagnetic induction principle is designed. First the cylindrical structure and working principle of the sensor are introduced, then the electromagnetic induction system of sensor is simulated by using Ansoft Maxwell, the magnetic field distribution and quiescent output voltage when current is 100 mA are obtained by static analysis, and by simulating sensors work process with transient modules, it comes to that the dynamic output signal is high frequency induced voltage,whose amplitude sinusoidally changed with the relative position of system. finally the adder detection circuit is designed according to the characteristics of the output signal. |
