| Outline of Final Research Achievements |
Development of motion analysis technique that targets the flexible body with large displacement, large rotation and time-varying length has been completed for planar motion of the flexible body. For extending to 3D motion and rigid -flexible systems, the high accurate and low calculation cost technique has been developed as the approximate method for the total numerical approach to the multibody systems.
The non-dimensional approach and multiple time scales were introduced to the Absolute Nodal Coordinate Formulation. The accurate verification has been confirmed in comparison with the experimental results. The validity of the proposed method was demonstrated.
