Sažetak
In this paper the problem of fluid-structure interaction of multibody systems with kinematically constrained large “ rigid body motion” in fluid flow are addressed. A spatial coupling algorithm that transfer the displacements from the solid to the flow and the pressure loads from the fluid to solid surface are based on Radial Basis Function interpolation with a compact support. Incompressible fluid is modelled by Navier - Stokes equations and solved in OpenFOAM toolbox. Mathematical model of multibody system dynamics is shaped as DAE system, while kinematical constraints violations are stabilized via constraint manifold projection method.
