摘要：
To obtain realistic dynamic characteristics of the lifting mechanism, the liftarm and drawbar were regarded as flexible bodies. The modal neutral file(MNF) of liftarm and drawbar were obtained from modal analysis conducted by finite element analysis(FEA) software MSC.Patran/Nastran. Then the MNF were translated into ADAMS, a rigid-flexible coupling model of the lift mechanism was built by replacing the rigid bodies with MNF. The forces of each hinge points in the rigid-flexible system, which were obtained from dynamic analysis, were compared with the rigid ones. The results showed that forces obtained from the rigid-flexible system were smaller than the rigid ones, which provided a reference for the design and improvement of the lifting mechanism.
