DETEKSI KERUSAKAN RING PISTON PADA MESIN EMPAT LANGKAH MELALUI PENGUKURAN SINYAL GETARAN
Abstract: The purpose of this
study is to develop the piston ring damage detection technique using
vibration analysis. Vibration analysis
was performed by measuring vibration in four stroke engine
which were worn and scratched on its piston ring, then compare it with the
vibrations generated by engine which had a
good conditions. Tests
carried out on
engine revolution of
750, 1500, and 2250
rpm, where the
sensor were placed
on the cylinder
head and cylinder block.
Vibration measurement produced a signal in the time domain, which then be
analysed their signal energy with the aid of Matlab software.
Result of the research showed that the vibration signal energy decrease in all of the strokes of the defect
piston ring. It was caused by the pressure of the defect
piston ring smaller than the good
piston ring’s. The decrease of vibration signal
energy in suction and compression stroke were greater
than the power and exhaust stroke. Indication of piston ring defect
could be shown from the decrease
in the vibration signal
energy in all
of the strokes.
