【Abstract】 This paper analyzes the mechanical features of the thin-walled joint structure which is widely applied in flight vehicles. A "fictious space-pin element" being representative of these features and a corresponding idealized method of the joint structure are suggested. The inter-constraint conditions among some nodal points of such idealized structure are presented. Two solutions of the displacement method under the conditions, the features of the corresponding assembling matrix equations and their applied range are briefly described.更多还原
