Impact resistance analysis of grille dam based on fluid structure interaction
نویسندگان
چکیده
Aiming at the impact failure of debris flow grille dam, considering interaction boulder-debris slurry- dam based on SPH-FEM, this article analyzed variation laws velocity, force and support reaction before after slurry boulders passing through dam. The results show that: SPH-FEM coupling method can truly reappear dam; velocity boulder are reduced by nearly 60% effect is remarkable; have secondary In first impact, greater radius boulder, force; in second has nothing to do with boulder.

Fluid-structure interaction studies on marine propeller
Composite propellers offer high damping characteristics and corrosion resistance when compared with metal propellers. But the design of a hybrid composite propeller with the same strength of metal propeller is the critical task. For this purpose, the present paper focusses on fluid-structure interaction analysis of hybrid composite propeller with Carbon/Epoxy, R-Glass/Epoxy and S2-Glass/Epoxy t...

متن کاملAnalysis of Fluid-Structure Interaction on an Aircraft Wing
Fluid–structure interaction problems in general are often too complex to solve analytically and so they have to be analyzed by means of experiments or numerical simulation. Studying these phenomena requires modeling of both fluid and structure. Many approaches in computational aero elasticity seek to synthesize independent computational approaches for the aerodynamic and the structural dynamic ...
