Mechanics and Control of Nonlinear Structures.
Abstract
This report documents results of analytical, computational, and experimental research on nonlinear structural analysis. In particular, a novel inverse dynamics method is presented whereby exact solutions for nonlinear dynamical response can be determined near a given approximate numerical solution. This method is useful for validation and tuning of dynamic response simulations. Also, novel results are reported for parameterization of NxN proper orthogonal matrices and applications in mechanics and control are explored. A novel quasi-coordinate method is developed for nonlinear flexible multi-body structural systems having a configuration variable mass matrix. This approach avoids the necessity of inverting the mass matrix through the derivation of differential equations which generate an instantaneously diagonalizing transformation. Finally, experimental results of maneuvers of the ASThEX Test Article are presented.
