Performance Analysis and Optimization of Flange Bolt Joint under the Influence of Inhomogeneous Temperature Field

摘要：

　　A three-dimensional mechanical model and a transcalent model of flange bolt joint were built,considering the nonlinearity of gasket and the contact problem,the effect of inhomogeneous temperature field and its variation to pressure of bolt and gasket was studied,and the joint parameters of two schemes were compared; based on the orthogonal text,two bolt system schemes,adding disc spring and adding sleeve,were experimentally studied.The investigation showed that the sealability of different parts of the gaskets is different,owing to the difference of each bolt in radial and axial displacement under the influence of inhomogeneous temperature field,and the fatigue of gasket and bolt is easily caused; the scheme of disc spring is better than sleeve,and the disc spring,whose thickness is 0.9mm,was selected to improve the mechanical performance of bolt system.
