大型水轮机顶盖振动传感器安装位置对比分析

摘要

本文通过对大型水轮机顶盖振动数据分析，研究传感器安装位置因素对数据采集可靠性的影响。对比分析不同安装位置振动传感器采集的数据后，发现靠近顶盖几何形心的内部和远离振动源的顶盖上部位置的传感器采集数据能够真实反映顶盖振动情况。%The effect of sensor installation position to the reliability of data sampling on vibration of a large turbine’s head cover is researched in this paper. Analysis on data from vibration sensors at different installation positions show that data from vibration sensors located near geometric centroid of head cover and far away from the vibration source can truely reflect the vibration on the head cover.
