摘要
在国内外工程实践中,迫切需要能在恶劣环境下进行实时扭矩测量的传感器。针对这一需求,提出了一种改进的环形球栅与交流电磁感应理论相结合的扭矩测量方法。从扭矩的机械概念着手,建立了传感器数学理论模型及相应的扭矩测量模型。对传感器的结构进行了优化和改进,用Ansoft Maxwell电磁有限元分析软件对该传感器进行了电磁仿真分析。结果表明:改进后的传感器能实现较好的测量效果,为后续的研究指明了方向。
In various mechanical systems, the torque is a typical variable, which can reflect the dy- namic performance of drive system. At the present, it was still difficult to measure torque under ex- treme environment. On the basis of the theory of ring-space arrays and the theory of electromagnetic induction, an improved non-contact torque sensor was put forward in the paper. Firstly, the paper es- tablished the models of the torque sensor and torque measurement from the mechanical conception of torque. Secondly, the focus of the paper was put on the optimization and improvement of the sensor＇ s structure. In the paper, a simulation model was established to research the improved sensor by An- soft Maxwell. The result showed that the improved sensor had a better measurement, which provided a good direction for the subsequent continuous research of the sensor.
