모드좌표와 절대절점좌표를 혼용한 동역학 해석기법에 관한 연구
Study on the Dynamic Analysis Method using the Modal Coordinates and the Absolute Nodal Coordinates
초록
In this paper, the absolute nodal coordinate formulation was introduced to describe the large deformation problems. And also, the modal coordinates were employed to represent the small elastic deformation. A new hybrid formulation was developed to combine the modal coordinates and the absolute nodal coordinates. A spherical joint and the DOT1 constraint were developed to carry out the numerical simulation of mechanical systems with kinematic joints. A beam example was suggested to show the new formulation. The simulation results using the modal coordinates and the absolute nodal coordinates show a good agreement to the experiments.
