Short summary
This paper proposes a novel 4-degree-of-freedom parallel mechanism. Its degrees of freedom are verified by screw theory. Inverse position, velocity, and acceleration models are established. The position workspace is obtained, and singular configurations are identified. The stiffness index distribution in the workspace is visualized. The inverse dynamic model is derived using the Lagrangian method. Kinematic and dynamic simulations in Adams verify the correctness of the theoretical model.
