应变测量在轴系扭转振动测试中的应用

Application of Shafting Torsional Vibration Measurement Based on Strain Measuring

针对目前船舶轴系扭转振动测试主要采用的角位移和角速度测量方法不能直接测量出轴系扭转振动应力,会造成一定程度的误差的问题,基于目前非常成熟的应变测量技术,对轴系扭转振动的测量进行分析,给出数据处理的方法,并提出基于无线遥测轴功率系统进行功率-扭振测试系统的开发和数据分析方法。

At present, marine shafting torsional vibration measuring is mainly by angular displacement or angular velocity measurement , which brings some errors because it could not directly measure vibration strain but make calculations .The methods of shafting torsional vibration testing using the mature strain measuring technique was analyzed to propose the way of development of a power-torsional vibration test system and data processing based on wireless telemeter of shaft power .
