This paper presents a novel three degrees of freedom parallel manipulator based on flexure structure. There are three limbs connected with a moving stage and a fixed platform. Each limb is configured with a multilayer elastic driven mechanism and four flexure hinges. The kinematics model and Jacobian matrix is derived. Dexterity and workspace as two of the most important performance indices are investigated...
The development of new compliant parallel mechanism (CPM) based on simulation driven design is a rapid approach to discover the unique features or advantages of conceptual model. In this research, a novel CPM which can generate three degrees-of-freedom translations are proposed. The kinematic model is derived. The finite element analysis is conducted to prove the feasibility of the proposed design.
There has been a growing interest of parallel mechanisms which offer a high degree of precision, stiffness and dexterity to name just a few of their benefits as opposed to their traditional serial counterparts. For the applications of parallel mechanisms in the field of sensor, previous work was focused on investigating the 6 degree-of-freedom force/torque sensors based on common Gough-Stewart platform...
There is an increasing requirement, in a variety of fields, for the ability to make microscopic movements or to position items with high degree of accuracy. In this paper, a parallel mechanism with prismatic actuators which encompasses three degrees of freedom and can produce motion on a microscopic level is proposed and developed. In order to produce such motion, the mechanism is composed of compliant...
