A new methodology for developing flexure-hinged displacement amplifiers with micro-vibration suppression for a giant magnetostrictive micro drive system

Kinetostatic and Dynamic Modeling of Flexure-Based Compliant Mechanisms: A Survey

“…There have been a considerable number of publications on the kinetostatic modeling of small-deflection compliant mechanisms [5][6][7][8][9][10][11][12]164]. The implementation complexity on this issue lies in the difficulty to deal with serial-parallel configurations often existing in compliant mechanisms [5][6][7].…”

“…Increasing applications of compliant mechanisms are extended to high speeds and high frequencies [5][6][7][8][9][10][11][12]262], thus determining their dynamic behavior is necessary and interesting. This can be crucial for evaluating/optimizing natural frequencies and for designing controllers.…”

“…Afterward, elastic and kinetic energies are calculated in the form of motion DOFs as shown in Eq. (12). At last, the dynamic model of compliant mechanisms can be further derived by employing Lagrange's equation…”

“…Flexure-based compliant mechanisms generally refer to mechanical devices gaining some or all of their mobility through elastic deformation of flexible members [1], which by nature possess the benefits of monolithic structure and variable stiffness over their rigid-body counterparts, thereby reducing friction, backlash, wear, no need for lubrication and assembly. Owing to these uniqueness, compliant mechanisms have been widely applied, including constant-force generation [2], multistable switches [3], micro-electro mechanical systems (MEMS) [4], precision positioning stages and grippers [5][6][7], micro/nanomanipulations [8], fast servotools in precision machining [9], servovalves [10], energy harvesting [11], microvibration suppression [12], alignment of optics, robotic actuation [13], and so forth.…”

Analytical Solution of Stiffness for a Corner-Fillet Leaf-Spring Type Flexure Hinge with a Long Fatigue Life

“…Compliant mechanisms are widely used in micro actuator [1][2][3], micromanipulator [4], displacement amplifier [5], micro/nano positioning stages [6][7][8][9], accelerometers [10][11][12] and sensors [13,14]. For micro/nano position stage, large stork and accurate displacement output, which make the displacement amplifying and guiding mechanisms become indispensable parts are two important goals to be achieved [15,16].…”
