摘要: 一、引言 为解决转子运行状态下叶片振动的测量问题,本文发展了多个探头组合的光电脉冲处理技术,并进行了误差估计。对于呈钟形分布而非尖型的单个脉冲,提出了新的信号计时基准,同时作了理论考证和实验分析。

Abstract: To measure the vibration of rotor blades in motion, this paper develops photoelectric pulse technique with multi-probes system and forms an error estimate of the calculating formulas.For a single pulse of bell shape but not sharp type, a new datum of signal instantaneous is proposed and checked through theory as well as experiment.
