The Stability

Because of easy for the bomb-stirring system of feed mechanism to reverse at its non-working position, which can affect the stability of the whole system. Virtual Prototyping Technology can help people to complete the design of overall structure of feed mechanism and anti-reversion mechanism of automaton. ADAMS, one kind of dynamics simulation software, can help to complete the motion characteristics analysis of anti-reversion mechanism, achieving the motion law of mechanism parts and movement dynamic characteristics, as well as verifying the rationality of the design of mechanism.

Abstract In this paper, a novel two-degree-of-freedom (2DOF) spherical parallel mechanism(SPM) with symmetrical structure is proposed and analyzed. First, the models of forward kinematics and inverse kinematics are established based on D-H parameters, and the Jacobian matrix of the mechanism is obtained and verified. Second, the workspace of the mechanism is obtained according to inverse kinematics and link interference conditions. Next, rotational characteristics analysis shows that the end effector can achieve continuous rotation about an axis located in the mid-plane and passing through the rotation center of the mechanism. Moreover, the rotational characteristics of the mechanism are proved and motion planning is carried out. A numerical example is given to verify the kinematics analysis and motion planning. Finally, some variant mechanisms can be synthesized. This work lays the foundation for the motion control and practical application of this 2DOF SPM.
