| description | A detailed analytical design for hybrid (metal-composite) bolted joints in static and dynamic (random vibrations) analysis is presented in this paper. Due to the fact that a space structure must be lighter and stiffened, the joints design represents an important aspect in the overall mass-stiffness optimization process of the structure. The hybrid joint studied represents the attachment between a real space thruster bracket structure made from aluminum alloy and a composite spacecraft platform subjected to quasi-static and dynamic loads. These computing techniques, originally designed for metal joints, were translated to hybrid metal-composite joints using the finite element method (FEM). As a result, using the FEM technique, the design methods proposed have validated the ability to incorporate and describe in detail the effects of important phenomena such as clamping, friction, clearance and secondary bending of the joint, which are complex three-dimensional phenomena of major importance in the design process of a hybrid joint. |
