| Abstract: | A parallel mechanism which has big workspace and fast movement was briefly introduced. Based on the vector relationship between platform and slider,the inverse kinematics of six-DOF parallel mechanism was derivated. And SimMechanies was used to simulate the mechanism. From analysing simulation results, the mechanism has balanced movement, smooth changed driven force, good performance of kinematics and dynamics. Rationality of the mechanism is validated. By optimizing the mechanism, the performance of kinematics and dynamics is improved, with the foundation in comprehensive optimization of structure established. |
