HOMOCLINIC ORBIT BIFURCATION OF A ROTATING TRUNCATED CONICAL SHELL

摘要

This is a study on Homoclinic bifurcation and subharmonic bifurcation of a truncated conical shallow shell rotating around a single axle and excited by a transverse periodic load. A systematic numerical approach is used to study the nonlinear motion of the system. The conditions under which bifurcations occur are determined on the basis of the characteristics of the rotating shell. Hamilton's singular distributions are also investigated in details.
