| Abstract: | From the structure of three degrees of freedom parallel mechanism, a three degrees of freedom motion simulation platform with one translational and two rotational is analyzed in this paper. This platform simplifies the structure by changing the length of the three collapsible support rods to achieve a specific position and orientation of the simulation platform. Based on Lagrange’s equation, the dynamic model of the 3-DOF parallel platform was established. The relation between system parameters and drive force of the mechanism was obtained, thus provides basis for the mechanical structural design. |
