抄録

This paper describes the evaluation of the performance of multibody dynamic analysis with natural coordinates. The computation time of the developed program was evaluated with multiple pendulums model and pendulums model with branch. Natural coordinates were compared with reference point coordinates in computation time of multibody dynamic analysis. These results showed the difference of the computation time between natural coordinates and reference point coordinates due to the topology of models.
