- Abstract:
- The modeling method for the compliant rod with large deformation was studied by using absolute nodal coordinate method, and the rigid-flexible coupling dynamic equations of the compliant mechanism were established.Considering the deformation characteristics of the compliant rod at the external connection, the new ANCF beam element with end deformation constraints was proposed.Based on the locking alleviation technique, the effect of the locking phenomenon of the absolute nodal coordinate beam element on the dynamic simulation of compliant mechanism was investigated.Finally, numerical examples were given to verify the accuracy and effectiveness of the absolute nodal coordinate method for the dynamic problems of compliant mechanisms．
