【Abstract】 The unrestrained piston ring curve has been analyzed by the finite element method. According to piston ring′s characteristics in the shape and working pressure as well as in its deformation state, an isoparametric element with 8 knots is used. The software to calculate the unrestrained piston ring curve is developed by using VC++. The calculating results have been tested and verified by means of the photoelastic method.更多还原
