Analytical results are presented on nonlinear vibrations of a post-buckled clamped beam constrained by an axial elastic spring subjected to combined axial-and-lateral excitations. Equations of the motion of the beam are derived including the term of parametric excitation due to the axial excitation. Nonlinear periodic responses are calculated with the harmonic balance method. Time progress of the beam, including non-periodic response, is calculated with numerical integration. Effects of the amplitude and phase of the axial excitation are carefully examined on the responses of the beam. It is found that transitions between non-resonance, principal and non-periodic responses are sensitive to the amplitude and phase of the axial excitation, which suggests a possibility of control on chaotic response.
