Abstract:A new type of flange) ) ) sulciform rigid flange with double-row holes was introduced. Some comparisons with traditional
flange were adopted to emphasize its advantages. It. s difficult to determine the stress state for its contact nonlinearity. onsidering
the material and contact nonlinearity, inner force analysis was done using finite element software. The distribution of stress
concentration area and the reasonable ratio of inside and outside bolt diameter were presented.
Keywords:rigid flange; contact nonlinearity; finite element analysis
