摘要
在空间坐标系中对旋转体上任意一点进行了的振动分析 ,利用激光多普勒技术设计了一种新型非接触式光学扭矩传感器 ,得到纯的扭振信号 ,消除了弯曲振动、线性运动、旋转体形状影响。
This paper analyses the vibration of an arbitrary point on the rotational shaft in the spacial coordinate system, designs a novel optical torque measurement method by laser Doppler technology, which can gain pure tortional signal and eliminate the influence of angular lateral vibration,rigid motion and the shape of ratational shaft cross-section.
