The purpose of the present study is to develop a procedure for performing dynamic analyses of large deformations in a flexible-framed structure as it moves along an arbitrary trajectory. Equations of motion that describe the force of inertia on a flexible-framed structure as it moves along an arbitrary trajectory have been derived using a finite element method. These equations also account for the geometric nonlinearity that must be considered when the deformation is large. A finite rotational matrix was used to transfer vectors or matrices from one reference frame to another. A computer program that gives a time history response has been developed using the derived equations. The validity of the program and the formulation as they relate to geometric nonlinearity has been verified by comparing the results calculated by the program in predicting a time history response with our experimental results, the results calculated by the analysis method indicated in the previous paper, and results calculated and published by another researcher. Time history responses for models that moved along various trajectories were also calculated by the program in this study.
