Multiple　degree-of-freedom　compliant　mechanisms　are　widely　used　in　the　fields　of　micropositioning　and　micro-manipulation.　This　paper　deals　with　multiobjective　topology　optimization　of　multi-input　and　multi-output　compliant　mechanisms　undergoing　large　deformation.　The　objective　function　is　defined　by　the　minimum　compliance　and　maximum　geometric　advantage　to　meet　both　stiffness　and　flexibility　requirements.　The　suppression　strategy　of　input　and　output　coupling　terms　is　studied　and　the　expression　of　the　output　coupling　terms　is　further　developed.　The　weighted　sum　of　the　conflicting　objectives　resulting　from　the　norm　method　is　used　to　generate　the　optimal　compromise　solutions,　and　the　decision　function　is　set　to　select　the　preferred　solution.　Geometrically　nonlinear　mechanism　response　is　calculated　using　the　Total-Lagrange　finite　element　formulation　and　the　equilibrium　is　found　using　an　incremental　scheme　combined　with　Newton-Raphson　iterations.　The　solid　isotropic　material　with　penalization　approach　is　used　in　design　of　compliant　mechanisms.　The　sensitivities　of　the　objective　functions　are　found　with　the　adjoint　method　and　the　optimization　problem　is　solved　using　the　Method　of　Moving　Asymptotes.　Numerical　examples　of　multiple　inputs　and　outputs　are　presented　to　show　the　validity　of　the　new　method.　Simulation　results　show　that　the　compliant　mechanisms　can　be　deformed　in　the　desirable　manner　and　the　coupling　output　displacements　are　suppressed　significantly　by　using　the　presented　method.　©　(2013)　Trans　Tech　Publications,　Switzerland.
