| Abstract: | Several approaches for developing the equations of dynamics of multi-rigid-body system were compared and discussed. The results show that Kane's method is one of the optimal approaches of motion equations for multi-rigid-body systems. Of further interest is the differential geometric meaning of the motion equations, by which numerical calculation accuracy of dynamic analysis could be improved. |
