Abstract:The accurate measurement of the torsional vibration of the engine crankshaft is crucial to the study of torsional vibration of the engine crankshaft and the vibration control. Based on the characteristics of the engine, research has been carried out on the processing algorithm and the precision of the electromagnetism sensor output speed signal, and then a practical torsion vibration signal processing method was given. It monitors with standard signals, and combines the numerical simulation of torsion vibration with the test bench to analyze the impact of the average speed and the sampling density on measurement accuracy.
