Abstract. Sleeve structure is used to joint component parts of aerocraft or other product design and manufacture. It is an incompletely rigid joint. The contact stiffness of sleeve structure is non-linear and it must be taken into account for static or dynamic analysis. The assembling technology of sleeve structure is influenceable on the natural attributes of the structure. In this paper, nonlinear finite element method with the gap element of MSN/NASTRAN is combined with hammering test to simulate the nonlinear contact problem of sleeve structure design and manufacture. A novel method is used to define the close stiffness of gap element. Effect of assembling technologic parameters on inherent characteristic of sleeve structure are studied, such as diameter, quantity, arrangement mode of joint bolts and the prestressing force on bolts. Processes of sleeve structure assembling are proposed through theoretically analysis and simulating calculation.
