主 题:Out-of-plane vibration Variable curvature Non-uniform beam Exact solution Mode transition
摘 要:The two coupled governing differential equations for the out-of-plane vibrations of non-uniform beams with variable curvature are derived via the Hamilton’s *** equations are expressed in terms of flexural and torsional displacements *** this study,the analytical method is ***,two physical parameters are introduced to simplify the *** derives the explicit relations between the flexural and the torsional displacements which can also be used to reduce the difficulty in experimental *** on the relation,the two governing characteristic differential equations with variable coefficients can be uncoupled into a sixth-order ordinary differential equation in terms of the flexural displacement *** the material and geometric properties of the beam are in arbitrary polynomial forms,the exact solutions with regard to the outof-plane vibrations of non-uniform beams with variable curvature can be obtained by the recurrence *** addition,the mode transition mechanism is revealed and the influence of several parameters on the vibration of the non-uniform beam with variable curvature is explored.
