Analysis of the Flexible Prismatic Pair Processing Errors of a Flexible Parallel Vibration Platform with High Frequency

Abstract:

In some fields, the rigid prismatic pairs have been gradually replaced by some flexible prismatic pairs. It is described a new type flexible prismatic pair in this paper. Its material is 65Mn spring steel. It is applied to the high frequency vibration field for its elasticity and structural advantages. The prismatic pair is based on a one-way four-bar linkage, which is consisted of some bent plate structures. Firstly its model is designed. Secondly the width error, the incision arc error and some other errors are analyzed in details. Based on the Paros J stiffness calculation formula and the Smith ST error analysis method, its relative stiffness error model is established. Finally by using finite element method, a simulation of deformation is made in the actual working conditions. And the error model is correct.
