Kinematics, workspace and static analyses of 2-DOF flexure parallel mechanism

چکیده
In this paper, we propose a 2-DOF parallel mechanism with flexure hinges. The kinematics and static analyses of this mechanism are studied in order to determine the kinematics properties, workspace, holding forces of the actuators and the reaction forces at the flexure hinges. These factors are useful for design process of this mechanism. The pseudo-rigid-body model (PRB model) of this mechanism is formulated. The theoretical results are compared with that obtained from ANSYS.
