Abstract
The space thermal environment and sophisticated deployable structure lead to the error of the satellite antenna. In this paper, a parallel-kinematic symmetrical stage to eliminate the error of antenna is proposed to realize the 2-DOF rotation with compact physical size. The flexure Hooke hinge is utilized to replace traditional U-joint with its characteristic of distributed compliance to eliminate the rotation clearance and to improve precision. This parallel mechanism is constituted of two symmetrical chains which are UPS kinematic chains with one spherical joint(S), one ball screw prismatic(P) and one flexure Hooke hinge(U) and one fix chain. Geometric analytical method is implemented to establish the kinematic model and the resolution of the parallel mechanism. A prototype stage is fabricated for experiment study. The open-loop testing is conducted to validate the stage's performance. Result show that the 2-DOF parallel mechanism possesses a compact dimension, which offers a workspace of ±2°×±2° with the repeatability precision of 0.01°.

Recommendations
Kinematic analysis of a flexible six-DOF parallel mechanism
In this paper, a new type of six-degrees of freedom (DOF) flexible parallel mechanism (FPM) is presented. This type of parallel mechanism possesses several favorable properties: 1) its number of DOFs is independent of the number of serial chains which ...
A comparison study of two planar 2-dof parallel mechanisms: One with 2-rrr and the other with 3-rrr structures
This paper deals with a comparative study of two planar two degrees of freedom parallel mechanisms: one with 2-RRR and the other with 3-RRR structures. For a fair comparison, both 3-RRR and 2-RRR mechanisms are symmetrical. The kinematics and Jacobian ...
Dynamics of the 6-6 Stewart parallel manipulator
Recursive matrix relations in kinematics and dynamics of the 6-6 Stewart-Gough parallel manipulator having six mobile prismatic actuators are established in this paper. Controlled by six forces, the manipulator prototype is a spatial six-degrees-of-...
