| Abstract: | The gripper structure and spring system clamped-free elastic rod. The motion equation of in practical technology are abstracted as deformed deformations of Euler elastic rod is established, according to the geometric form and the balance conditions of mechanics. The solutions of the mathematical model, the form of the deformed elastic rod as well as the related multiplicity and the bifurcation of the solutions are obtained. |
