- Abstract
A certain type of engine casing is usually connected by bolts. The reliability and stability of bolt connection have a great influence on the mechanical characteristics of the casing. By establishing the finite element analysis model of casing and bolt, the influence of bolt preload on the axial tensile stiffness of casing bolt connection structure is studied. The results show that, when the bolt preload is small, the axial tensile stiffness of the casing bolt connection structure increases gradually with the increase of the preload; when the preload increases to a certain value, the axial tensile stiffness of the casing bolt connection structure tends to be stable; when the preload is too large, it will cause the plastic deformation of the bolt and the connection surface, which will lead to the failure of the connection structure and reduce the axial tensile stiffness.
