摘要：

The　traditional　pseudo-rigid-body　model　(PRBM)　has　one　degree　of　freedom　(DOF)　and　performs　a　good　simulation　to　the　tip　locus　of　flexible　links　for　compliant　mechanisms　on　the　basis　of　a　parametric　approximation　method.　In　this　study,　a　new　approach　of　a　two-DOF　PRBM　is　proposed　to　simulate　both　the　tip　locus　and　tip　deflection　angle　of　large-deflection　links　for　compliant　mechanisms　on　the　basis　of　the　angular　deflection　approximation　technique.　A　linear　regression　for　the　spring　stiffness　coefficient　of　the　2R　PRBM　using　the　optimization　technique　is　presented.　The　advantage　of　the　new　model　is　well　illustrated　through　a　numerical　comparison　between　the　1R　and　the　2R　PRBM.　©　2010　Higher　Education　Press　and　Springer-Verlag　Berlin　Heidelberg.
