| Abstract: |
| The method by which the movements of 7R mechanism can be analyzed all sidedly was introduced. The method of rotation vector was used to build the mathematical model of the 7R spatial mechanism. The kinematic quality of the 7R Mechanism was analyzed with the method of numerical differential and transferring function of MATLAB, the velocity and acceleration of any point on any link were figured out and expressed by the drawing functions. The trajectory, velocity and acceleration of any point on any link were analyzed through the examples. The results can be used as the fundation of theory when the other spatial mechanism is to be analysed. |
