Paper Abstract

The input coupling term is one of the important factor need to be considered in designing a precision micro-positioning mechanism. Couplings between the input bodies will cause a serious difficulty in motion control. An input coupled terms analysis method was presented for a 3-DOF micro-positioning parallel compliant mechanism. Firstly, the pseudo-rigid-body model of the mechanism was presented, an input coupled terms prediction method was developed based on the linearization theory. Secondly, using the finite element method validated the prediction method. Finally, the influences of the structural parameters to the input coupled terms were discussed. The results are helpful to design a low input coupling terms micro-positioning system.
