The Differences of the Instantaneous Speed Fluctuations for Diesel Engine Flywheel and the Free End

Monitoring of instantaneous speed of diesel engine is a new state analysis,the measurement of the general use of magnetic sensors in the engine flywheel end or the free end of the installation of gears.Sensor is installed on the instantaneous speed fluctuations measurements are different,the results of the analysis of the state.In this paper,examples of simulation and measurement side with the free end of the engine flywheel to measure the instantaneous speed fluctuation analysis of the differences obtained in the flywheel-side installation of the sensor can directly reflect the dynamic performance of the machine to measure the location more desirable.
