| Summary: | This paper presents the output decoupling property of planar flexure-based
compliant mechanisms with symmetric configuration. Compliance/stiffness
modeling methods for flexure serial structures and flexure parallel
structures are first derived according to the matrix method. Analytical
model of mechanisms with symmetric configuration is then developed to
analyze the output decoupling property. The proposed analytical model shows
that mechanisms are output decoupled when they are symmetry about two
perpendicular axes or when they are composed of either three or an even
number of identical fundamental forms distributed evenly around the center.
Finally, output compliances of RRR and 4-RRR compliant micro-motion stages
are derived from the analytical model and finite element analysis (FEA). The
comparisons indicate that the results obtained from the proposed analytical
model are in good agreement with those derived from FEA, which validates the
proposed analytical model. |
