摘要
研究了旋转体转速在实际空间坐标系与成像空间坐标系中的转换关系,利用新型连续光反射条纹技术,通过光学成像系统在线阵CCD上得到反映连续转速信息的光强信号,经过信号调理后得到被测体转速信息,解决了旋转机械瞬态性能分析中瞬态转速测量中存在的缺陷,建立起一种简单的速度压缩模型,为新型连续转速测量提供了一种参考。
It studys the relationship of the rotating shaft in the real spacial coordinate system and the imaging spacial coordinate system.An novel rotating speed sensor is designed with linear CCD,and the deficiencies of the instantaneous rotating speed measurement in the instantaneous characteristic analysis of rotating engine are solved.A simple speed compress model is built up.It provides a well reference to other applications in the field of rotating speed measurement.
