Abstract: The deformation of a lumped complete compliant slider mechanism was analyzed with pseudo-rigid-body model method.A micro-compliant slider mechanism was designed,in which the prismatic pair of it was designed and analyzed mainly.The equivalent spring force of slider pair of the designed sample was presented.Furthermore the result of analysis in pseudo-rigid-body model for the sample is given.Otherwise,the simulation analysis in the FEM method for the example is also given.The results obtained by the two methods are approximated. This indicates that the analysis and design methods are correct and feasible.
