扭振测量仪低速性能的改进

An Investigation on Torsional Vibration Instrument for Low Speed Functions

非接触式扭振测量仪是内燃机及其动力装置轴系扭振测量发展的方向 ,但是目前常见的非接触式扭振测量仪对于大型低速船用柴油机轴系的扭振测量尚不适应。为此需对非接触式扭振测量仪进行低速性能改进。本文所研究的就是对现有的非接触式扭振测量仪检测中的某些局限性提出改进措施 ;

It is development trend to measure the torsional vibration of internal combustion engine with noncontact sensory technique.But the ordinary non-contact instruments are not fit for the measurement for large low speed diesel engines used in ships.So it is necessary to improve their functions at low speed.This paper has investigated the improvement on test circuit of a non-contact torsional vibration measurement.A comparative experiment has been completed and a feasible method is found.
