Abstract：

This paper presents conceptions: coefficient of bent stress concentration at transitionpart of hydro-cylinder flange; relative ratio of circular bead radius for the first time. This paper infersmechanical calculating formula of confficient of bent stress concentration; clarifies reasonable valueextent of relative ratio of circular bead radius at theory and at this foundation infers a axial stresscalulated formula for engineering application. This paper is of great importance for hydro-cylinder de-signing and its theory study.
