Analytical Characterization of Spatial Compliant Mechanisms Using Beam Theory

A pseudo-rigid-body approach for determination of parasitic displacements of lumped compliant parallel-guiding mechanisms

“…In this way, the unwanted effects of friction, bucklash, and wear, which always appear during the exploitation of mechanisms with classic joints, were avoided. In the literature, various procedures have been developed for kinetostatic and dynamic analyses of compliant mechanisms such as the transfer matrix method [6][7][8][9][10], the dynamic stifness method [11,12], the beam theory based method [13][14][15], the pseudo-rigid-body model [16][17][18][19][20], the finite element method [21][22][23], the multi-compliant-body matrix method [24], the compliance matrix method [25][26][27], the Castigliano's second theorem based method [28], the unit-load method [29] etc. A survey of results, methods, and ongoing problems in compliant mechanisms research field was given in [30].…”
