| Abstract: | The 2-DOF spherical motion parallel mechanism has three kinematic chains, and two of them are drivable, another is passive. The mechanism is unsymmetrical. Analysis of position and velocity for it has been processed, which offers theory foundation for its being controlled. The mechanism has already successfully been applied on test-bed of automotive transmission, which develops the application of few-DOF parallel mechanism. |
