모드좌표를 이용한 Beam의 동역학적 해석과 대변형 실험을 통한 비교 연구

Dynamic analysis of flexible multibody systems can be obtained by computer simulations or experiments. For the computer simulations. absolute nodal coordinates or deformation modal coordinates are used to represent the deformation. In this study, elastic deformation of beams are measured by experiments, and compared with computer simulations wi th modal coordinate method in the DADS program. The accuracy of the modal coordinate formulation in large deformation is verified.
