Abstract
This paper presents a reduction method of system matrices for the absolute nodal coordinate formulation based on continuum mechanics approach, in the case of planar flexible beam, by applying the component mode synthesis. Numerical examples that compare the presented method and the conventional ANCF are demonstrated to verify the validity of the presented method. As a result, it is verified that the presented method achieves the shortening of the computing time, while keeping the acceptable accuracy of the expression characteristics of the conventional ANCF on large rotation and large deformation.
