| Abstract: | The ANSYS is used to establish 3D finite element model of a 6-DOF Manipulator.The joints are simulated by coupling the degrees of freedom of the coincide nodes.Then natural vibratory frequencies and modal vibratory models of the lower six orders are obtained,and the vibration weakness of the structure is found out,which gives the basis for structure improvement. |
