The revolute outputs effected by the clearances of joints which are caused by the inaccurate precision of processing and error of assembly are analyzed at first, then in order to illustrate the problem the simulation of a kind of parallel mechanism named 3-PRUR is also done in Pro/E and Adams software. At last a kind of compliant revolute joint called split-tube flexural pivots based on the principle...
This paper presents the development of a micro-scale positioning device based on two degrees of freedom (DOF) plane compliant parallel mechanism, which is featured by piezo-driven actuators and flexure joints, integrated force/torque sensor that capable of delivering 2-DOF motions with high precision and providing real-time force/torque or position information for feedback control. With optimization...
In order to realize vibrations from one dimension to three dimension, three-translational parallel mechanism was used as the main mechanism of the micro-vibration platform, flexible hinge was used as the kinematic pair, thus the small and equivalent movement could be achieved through the elastic deformation of the material, and the error of the connection could be minimized. By analyzing the relationship...
This paper presents a novel 3-DOF precision positioning stage for nanoimprint lithograph (NIL). Due to the advantages such as high positioning accuracy, dexterity, low inertial, and balanced mechanical structure, a piezo-driven flexure-based parallel mechanism is utilized. Based on Pseudo-Rigid-Body modelling theory, the kinematics of the stage is developed by simplifying the single-axis flexure hinges...
