Abstract:
In order to restrain the vibration of a flexible manipulator, an assembled flexible link is used in the flexible manipulator to improve the dynamic performance of the flexible manipulator. Through the exper-i mental research and FEA ( Finite Element Analysis) simulation on bending of pre-pressed mult-i layer assembled flexible link, it is indicated that this kind of flexible link has favorable hysteresis characteristic, which varies with the pre-pressing force, and can effectively restrain the vibration of the flexible manipulator. Moreover, FEA simulation is applied to this kind of flexible link with ANSYS under considering geometric nonlinearity and contac-t status nonlinearity. Its load-deflection graph with the hysteresis characteristic is consistent with the experimental result. This method provides an effective way for the research on the statics and dynamics of the assembled flexible link.
