“…For example, the pseudo-rigid-body model has been widely used for the kinetostatic and dynamic analyses of flexure grippers by modeling flexure hinges as equivalent joints with a spring, such as several types of flexure-based grippers designed by Chen and coworkers [233,234], Wang et al [235], Tian and coworkers [117,236,237], and so on. Other pioneering works were applying the pseudorigid-body model to the design and analysis of precision positioning stages by Li and coworkers [238,239], Wan and Xu [240], Tian and coworkers [241][242][243], Liu et al [244], and so forth.…”

“…In Eq. (12), the elastic energy can be easily calculated with the prepared input or output stiffness at the stage of kinetostatic analysis, differing from the pseudo-rigid-body model wherein the elastic energy is the summation of all characteristic springs [233][234][235][236][237][238][239][240][241][242][243][244] and kinematic solutions are required for calculating the total elastic energy. On the other hand, the kinetic energy in Eq.…”

Flexure-based compliant mechanisms are becoming increasingly promising in precision engineering, robotics, and other applications due to the excellent advantages of no friction, no backlash, no wear, and minimal requirement of assembly. Because compliant mechanisms have inherent coupling of kinematic-mechanical behaviors with large deflections and/or complex serial-parallel configurations, the kinetostatic and dynamic analyses are challenging in comparison to their rigid-body counterparts. To address these challenges, a variety of techniques have been reported in a growing stream of publications. This paper surveys and compares the conceptual ideas, key advances, and applicable scopes, and open problems of the state-of-the-art kinetostatic and dynamic modeling methods for compliant mechanisms in terms of small and large deflections. Future challenges are discussed and new opportunities for extended study are highlighted as well. The presented review provides a guide on how to select suitable modeling approaches for those engaged in the field of compliant mechanisms.

“…For the replacement, the same initial position of the compliant mechanism with the crank angle γ is used as in the rigid-body model. The Roberts mechanism with four hinges is a typical path-generating mechanism which is used for the rectilinear guidance of a coupler point in precision engineering applications, for example [19][20][21][22].

A compliant mechanism gains its mobility fully or partially from the compliance of its elastically deformable parts rather than from conventional joints. Due to many advantages, in particular the smooth and repeatable motion, monolithic mechanisms with notch flexure hinges are state of the art in numerous precision engineering applications with required positioning accuracies in the low micrometer range. However, the deformation and especially motion behavior are complex and depend on the notch geometry. This complicates both the accurate modeling and purposeful design. Therefore, the chapter provides a survey of different methods for the general and simplified modeling of the elasto-kinematic properties of flexure hinges and compliant mechanisms for four hinge contours. Based on nonlinear analytical calculations and FEM simulations, several guidelines like design graphs, design equations, design tools, or a geometric scaling approach are presented. The obtained results are analytically and simulatively verified and show a good correlation. Using the example of a path-generating mechanism, it will be demonstrated that the suggested angle-based method for synthesizing a compliant mechanism with individually shaped hinges can be used to design high-precise and large-stroke compliant mechanisms. The approaches can be used for the accelerated synthesis of planar and spatial flexure hinge-based compliant mechanisms.

“…Qin et al proposed a decoupled XY stage using statically indeterminate symmetric structure [18]. Xu et al designed a parallel-kinematic XY micro positioning stage based on flexure Roberts mechanism [19]. Generally, the decoupling mechanism would connect serially between motion stage and actuation mechanism, but few studies concentrate on the position configuration relationship among the actuator and its preloaded mechanism, as well as the kinematic decoupling mechanisms in the mechanical design process, which will significantly influence the compactness and M dynamic characteristics of micro/nano positioning system.…”
