Abstract Piezoelectrically actuated compliant mechanisms are key techniques in designing micro/nano manipulators, precision positioning stages/grippers and many other mechanical instruments. By considering the coupling relationship among piezoelectric actuator, compliant mechanisms and their external loads, a new modeling methodology in Laplace domain is proposed to capture the coupling dynamic characteristics of such a complex system. The coupled dynamic model of piezo-actuated compliant mechan...

Abstract Beam-based Compliant Mechanisms (CMs) are increasingly studied and implemented in precision engineering. Straight beams with uniform cross section are the basic modules in several design concepts, which can be deemed as standard CMs. Their behavioral analysis can be addressed with a large variety of techniques, including the Euler–Bernoulli beam theory, the Pseudo-Rigid Body (PRB) method, the beam constraint model and the discretization-based methods. This variety is unquestionably redu...

In this article, an XY parallel nanomanipulator with multiple actuation modes (PNM) is proposed, analyzed, and tested. Arising from the parallel mechanism of a machine tool, the PNM is featured with multiple actuation modes and configurable parallel chains. Analytical models with different approaches are established to compressively understand the presented PNM. Workspace distribution and reachability are analyzed under different actuation modes in a detail manner. The models also reveal the com...

Abstract Precision components in optical instruments enjoy the benefits of kinematic flexure mount, owing to its excellent performance evident in space telescope and lithography equipment. The stiffness behavior of a flexure mount is important for releasing thermal stress and resisting displacement. However, they still need enough investigation and design guidance. In this paper, a novel kinematic flexure mount comprising three identical chains, is proposed based on exact constraint principles. ...

Abstract Compared with the lever-type amplifier, the rhombus-type amplifier has attracted more attention by virtue of large displacement amplification ratio, compact structure, and linear output displacement. In this paper, a novel electromagnetic force balance sensor (EFBS) based on the rhombus-type amplifier is presented to measure the mass with high precision. First, the structure and operating principle of the EFBS are described, and the requirements for the design and manufacture of the amp...

In this article, a new two-dimensional piezoelectric actuator driven vibration stage is proposed and prototyped. A double parallel four-bar linkage structure with double-layer flexible hinges is designed to guide the motion and reduce the displacement coupling effect between the two directions. The compliance modeling and dynamic analysis are carried out based on the matrix method and Lagrangian principle, and the results are verified by the finite-element analysis. A closed-loop control system ...

Abstract Compliant mechanisms have become an important branch of modern mechanisms. Unlike conventional rigid body mechanisms, compliant mechanisms transform the displacement and force at least partly through the deformation of their structural components, which can offer a great reduction in friction, lubrication and assemblage. Therefore, compliant mechanisms are particularly suitable for applications in microscale/nanoscale manipulation systems. The significant demand of practical application...

Abstract. This paper presents an improved modeling method for bridge-type mechanism by taking the input displacement loss into consideration, and establishes an amplification ratio model of bridge-type mechanism according to compliance matrix method and elastic beam theory. Moreover, the amplification ratio of the designed bridge-type nano-positioner is obtained by taking the guiding mechanism as the external load of bridge-type mechanism. Comparing with existing methods, the proposed model is m...

Abstract Serial-parallel configurations are widely designed in compliant mechanisms. In this paper, the transfer matrix method is combined with D'Alembert's principle to develop a two-port dynamic stiffness model for analyzing the kinetostatics and dynamics of complex compliant mechanisms with serial-parallel configurations. In detail, two kinds of improved transfer matrices for parallel sub-chains are derived in a unified form by summarizing the common serial-parallel substructures in compliant...
