Fully compliant mechanism of incomplete distributed compliance is a kind of new compliant mechanism whose compliance is between lumped and distributed. According to the characteristic of this compliant mechanism, a new analyzing model based on pseudo-rigid-body model named imitate-compliant-body model was presented. The imitate-compliant-body model of rectangular flexure hinge and link was established. The coefficient of load ratio μF and correct coefficient μλof the model were also defined. Finally the results of five samples using the imitate-compliant-body model were presented. Through the experimental test of the five samples and the compare of the results with computer and test, the validity of this model was proved.
