In this paper, the design of a new compliant five-axis parallel nanopositioning stage driven by PZT actuators is presented, which is based on flexure mechanism. The flexure stage contains two kinds of displacement amplifiers based on simple lever principle and bridge principle, respectively. The lever structure is designed to meet the requirement of the change of direction of the output displacement...
In the family of large-range flexure systems, large-deflection flexural pivots, linear-motion guiding stages, XY compliant parallel micromanipulators (CPMs) are commonly used in a variety of fields. The issue related to their design, however, is concerned with minor literatures. In this paper, we focus on the design of these large-range flexure systems from the view of constraint-based design principle...
Piezo-actuated micro/nano manipulators have been extensively investigated in the past decades. A large number of prototypes and products were developed to perform micro/nano operations. In general, once built, the characteristics of a micro/nano manipulator are fixed and not changeable. Therefore, one manipulator is particularly well-suited to certain special tasks. A new modularized design methodology...
Overlay alignment is a key technology in multi-layer Roll-to-Roll inkjet Printing. To eliminate or reduce the defects, an active compensation compliant mechanism is proposed to compensate the errors occurred during production. The mechanism consists of four parts which provide the printhead 5 DOFs to compensate errors actively. In this paper, the design of the whole device is presented. The kinematics...
Micrograsping devices and methodologies play an important role in the performance of high precision positioning systems as they contact the objects to be grasped directly. The polarization maintaining optical fiber's asymmetry structure generated a polarization axial, so rotational alignment is an extremely important issue to be concerned. To fulfill the demand of grasp and rotation in optical fiber's...
This paper presents the design, analysis, and characterization of a compliant thoracic mechanism that saves inertial power for flapping-wing micro air vehicles. Lightweight polyimide film hinges were previously integrated into a compliant flapping-wing mechanism to reduce friction. However, these were not stiff enough to fully recover wing's inertial energy into elastic energy. To store adequate elastic...
The compliant double parallel four-bar mechanism is a classical parallel guiding mechanism. Two mathematic models of double parallel four-bar mechanism were built based on pseudo-rigid-body model and elastic beam theory. The elastic beam theory was used to analysis the effect of axial deformation on the displacement of moving plate at large displacement. Effect of compliant guiding beam geometric...
