| Abstract: | A calculation method for moving inertia of diesel crankshaft journal has been proposed.The intemal exciting source of shock vibration on engine body side and its inner relations with engine con-dition, lubricant temperature and main journal bearing clearance have been revealed by theoretical analy-sis on crankshaft axial moving inertia and simulation test on tribological fault of main journal bearing, anew on - line vibration method for monitoring the tribological fault on diesel main journal bearing has beenput forward. |
