The fatigue characteristics of casted engine cylinder by aluminum alloy has been analyzed by using staircase method.Fatigue strength limit and standard deviation have been determined under a certain reliability and validity.The research indicates that the S-N curve of the cylinder contains a section of straight line,which means it has a limit of fatigue strength.The result offers the foundation for further research on fatigue life of cylinder.
