In this paper, a new compliant parallel mechanism driven by piezoelectric actuators is designed, which is a modified structure from our previous designed stage. In order to compensate the limited stroke of PZT, the secondary amplification mechanism was adopted in this design, and also the matrix method is utilized to calculate its stiffness and compliance for this compliant mechanism. In practical...
In this paper, a matrix equation method, a dimension-reduce then dimension-increase matrix method is proposed to model leverage structure and closed-loop structure of compliant mechanism, respectively. The accuracy of the methods is validated by finite-element analysis (EFA).
With the purpose of designing a completely decoupled XY micro-motion stage, a novel flexure hinge-based compliant parallel mechanism driven by piezoelectric actuators (PZT) is presented in this paper. The mechanism with a double symmetric structure is constructed by employing double fourbar flexures as prismatic joints due to their better stiffness performance. To obtain an accurate model, matrix...
This paper presents a novel macro/micro 3-DOF parallel platform for micro/nano positioning applications. The kinematics model of the dual parallel mechanism system is established via the stiffness model of individual wide-range flexure hinge and vector-loop equation. The inverse kinematics is analyzed and simulated on a parallel mechanism with real parameters. Whereafter, the reachable and usable...
