中文摘要：

目前国内外对高温、高湿、强腐蚀、强冲击等极端恶劣环境下的扭矩测量仍无有效检测方法,针对该现状,在提出的一种由环形球栅与磁电式检测器组成的新型非接触式扭矩传感器的原理基础上,重点从传感器的结构特点出发,结合磁路理论对环形球栅检测器的原理进行了较为深入的研究,并利用ANSYS软件对设计的球感检测器进行电磁分布特性分析与实验。经初步实验验证,该环形球栅检测器能满足极端环境下的扭矩动态测量。

英文摘要：

In various types of mechanical spindle drive, the torque is one of typical variables for reflecting the dynamic performance of mechanical system. By analyzing the torque, it can be available for the performance parameters of the whole drive system. There is no effective method for torque measurement under extreme environment, such as high temperature, strong impact, and strong vibration and so on. The paper brought out a new non-contact torque sensor, which adopt alternating electromagnetic induction ball grid technology, and was composed of specially designed ring-space arrays and dedicated magnetic detector. And it took emphases on the structure, principle of torque sensor. A simulation model was built to study the electromagnetic distribution characteristics of the detector by ANSYS. The experimental results verify that the detector can meet the dynamic torque measurement requirement in the extreme environment
