TO REDUCE IMPACT NOISE OF THE VALVE BY USING SILENT VALVE PLATE.

Author(s) : QIAN X.

Summary

THE AUTHOR INDICATES THAT THE NOISE PEAK FREQUENCY COMES FROM MECHANICAL SHOCK ; INVESTIGATING THE FREQUENCIES OF NOISE SOURCES, THE NOISE PEAK FREQUENCY IS FOUND -THE IMPACT PAIRS OF THE VALVE PLATE AND THE SPRING. THE CAUSE TO RAISE THE NOISE IS ON THE PHENOMENON OF DETACHMENT BETWEEN THE VALVE PLATE AND THE SPRING. FOR THIS REASON THE VALVE PLATE PRODUCES HIGH FREQUENCY VIBRATION BY THE EXTERNAL EXCITATION. THE EFFICIENT WAY TO REDUCE THE IMPACT NOISE IS TO ADOPT THE HIGH DAMPING MATERIAL.
