Journal: Internal Conbustion Engine & Power Plant
Keyword: Ductile Iron; Fracture Analysis; Bearing Seize; Torsion Crack;
Abstract: The reasons that fracture a ductile iron crankshaft are analyzed with the methods of fracture analysis,microscopic detection,chemical composition detection and mechanical property test. The measurement results indicate that the crankshaft meets the requirements of drawings. The key reasons causing the crankshaft being broken is that the bearings are seized when the engine is running.
