Abstract： The dynamic approximation method for the position analysis of the planar multi-bar mechanism proposed in this paper is based on the "rod length approximation method". In the iteration, the characteristics of the motion transmission of the planar mechanism are paid attention to, and the speed and acceleration information of the rod movement can be used to achieve super the quadratic convergence rate.
