Abstract
This paper describes the evaluation of real-time performance and computation time of the multibody dynamic analysis with natural coordinates. The real-time performance was evaluated with the model of multiple pendulums. The multibody dynamic analysis with natural coordinates were compared with reference point coordinates in computation time and real-time performance. Calculation result shows that the computation time of multibody dynamic analysis with natural coordinates were faster than that of the reference point coordinates on the multiple pendulums, and the real-time performance of natural coordinates is more effective than that of reference point coordinates.
