Sažetak
Compliant mechanisms gain at least part of their mobility from the deflection of flexible members rather than from movable joints only. They are an alternative to conventional sliding and rolling mechanisms and used to transfer motion, strength and energy and characterised by high precision, possibility of monolithic manufacturing (‘design for noassembly’) and of parallel kinematics, as well as reduced costs, no backlash and wear. Compliant mechanisms are nowadays widely used in mechanical engineering design, precision engineering as well as technologies for micro and nanosystems. In this work, various analytical and numerical methods are used to evaluate the behavior of compliant rotational mechanisms, known as cross-spring pivots, for applications in micropositioning. A cross-spring pivot allows a movable block to rotate with respect to the fixed block through the deflection of leaf springs in a common layout configuration. The limits of applicability of approximate calculation algorithms must be determined when ultra-high precision is required. The results obtained by using these methods are thus compared with results obtained through the generalized nonlinear Elastica-type approach, results obtained by the use of FEM analyses as well as experimental data published in literature. The aim of this part of the work is to evaluate the effect of the various design parameters on minimizing the parasitic shift of the pivot's geometric centre as well as minimizing the variance of the pivot's rotational stiffness in order to ensure its stability and avoid possible buckling occurrence. The results obtained thus allow the determination of design solutions that are appropriate in applications for ultra-high precision micropositioning. This work has been supported by University of Rijeka under projects number uniri-pr-tehnic-19-21 and uniri-tehnic-18- 34 and also by Croatian Science Foundation under the project number IP-2019-04-3607.
