Research Abstract |
Mathematical model is constructed for a 2-dimensional flexible beam as elemental factor of flexible deployment structure for space applications. The mathematical model is constructed based on Absolute Nodal Coordinate Formulation (ANCF) method and conventional internal viscosity model and proposed air drag force model are considered in the formulation. A dynamic stiffening effect which is a motion with large rotation and deformation is focused on because deployment structures often experience such an effect. Experimental validations about conventional internal viscosity model and air drag force model show good correspondences.
