High-speed presses knowledge: Crankshaft Fatigue Life
Crankshaft is one of the high-speed presses transmission core member having an important role in transmitting torque, output power. The third chapter of the crankshaft through fault tree analysis showed that: crank shape complex structure, while working in the complex cyclical bear variable load, thus resulting in structural fatigue failure is the failure of high-speed presses mechanical structure failure rate than Gao, more seriously affected fault one category. Crankshaft work will analyze stress and strain on the basis of the crank stamping process simulation, and using fatigue analysis software crankshaft fatigue analysis and life prediction, looking for weak areas crankshaft fatigue, and to develop appropriate measures to improve the process and maintenance of Crankshaft Fatigue Reliability .
