Sažetak
A cross-spring pivot allows to achieve the rotation of a movable block via the deflection of leaf springs. When ultra-high precision is required, parasitic shifts have to be considered and the limits of applicability of approximated calculation algorithms have hence to be determined. The results obtained by employing these methods are thus compared with results obtained by using nonlinear finite element analysis (FEA), results obtained via the nonlinear Elastica approach as well as experimental data. FEA calculations allow also considering the influence of lateral loads and of non-symmetrical pivot configurations. An ultra- high precision design configuration allowing the minimisation of the parasitic shifts and of the variability of rotational stiffness, even for large rotations, is thus obtained.
