测量扭矩的方法和系统
摘要：
本发明提供一种测量扭矩的方法/系统。该方法/系统包括提供具有目标图形的第一转盘A和提供具有目标图形的第二转盘B。该方法/系统包括提供具有至少三个传感器的第一传感器组，其包括第一盘第一传感器(1A)、第一盘第二传感器器(2A)、及第一盘第三传感器(3A)。该具有至少三个传感器的第一传感器组用于检测第一转盘目标图形，其环绕第一转盘固定。本方法包括提供具有至少三个传感器的第二传感器组，包括第二盘第一传感器(1B)、第二盘第二传感器(2B)、及第二盘第三传感器(3B)。具有至少三个传感器的第二传感器组用于检测第二转盘目标图形，其环绕第二转盘固定。该方法/系统包括利用具有至少三个传感器的第一传感器组和具有至少三个传感器的第二传感器组检测第一转盘相对于第二转盘的表观扭转，并根据测得的表观扭转确定实际扭转角度。
摘要（英）：

The invention provides a method/system for measuring torque. The method/system includes providing a first rotating disk A having a target pattern and providing a second rotating disk 13 having a target pattern. The method/system includes providing a first set of at least three sensors, comprised of a first disk first sensor (1 A), a first disk second sensor (2A), and a first disk third sensor (3A), the first set of at least three sensors for sensing the first rotating disk target pattern with the first set of at least three sensors fixed around and encompassing the first rotating disk. The method/system includes providing a second set of at least three sensors, comprised of a second disk first sensor (lB), a second disk second sensor (2B), and a second disk third sensor (3B), the second set of at least three sensors for sensing the second rotating disk target pattern, with the second set of at least three sensors fixed around and encompassing the second rotating disk. The method/system includes measuring an apparent twist of the first rotating disk relative to the second rotating disk with the first set of at least three sensors and the second set of at least three sensors, and determining an actual twist angle from the measured apparent twist.
