摘      要:Recently the Kirchhoff rod and the methods of dynamical analogue have been widely used in modeling *** features of a DNA such as its super slender and super large deformation raise new challenges in modeling and numerical simulations of a Kirchhoff *** this paper,Euler parameters are introduced to set up the quasi-Hamilton system of an elastic rod,then a symplectic algorithm is applied in its numerical ***,a simplified surface model of the rod is given based on the hypothesis of rigid cross-section.
