| Abstract: | A Dual-dam Model of fatigue reliability design for engine crankshaft is presented in this paper. The outer dam of the model represents the crankshaft fatigue strength and the inner represents the changing stress of automotive engine crankshaft under various operation modes. The dual-dam model shows the operation state of crankshaft by virtue of the correlation between its strength and working stress. The reliability of crankshaft can be calculated by means of theory of equivalent life of conditional reliability. |
