轴系扭振和横振的激光测量

Measuring Torsional and Transversal Vibrations of Rotating Shafts Using Laser

本文全面分析了多维振动状态下旋转轴表面光的散射特性，提出了利用激光技术实施旋转轴系扭振和横振测量的方法。以扭振和横振的合并测量为基础，能实现两种振动的独立测量，且扭振测量不受轴系横振因素的影响。

In this paper the multi-dimension movement of a roasting shaft under vibrations is studied and a novel method of optical measurement of torsional and transversal vibrations in a drive train is proposed. With modern optoelectronic digital signal processins and microcomputer techniques, the measuring device is developed.
