This research investigates chaotic vibration of a rigid rod attached on parallel strings under periodic lateral excitation experimentally. Two parallel strings are stretched and the rigid rod is attached at unsymmetrical position on the strings. Chaotic responses of the rigid rod are examined by the power spectrum, the Poincare section, the maximum Lyapunov exponent and the principal component analysis. By changing the excitation frequency, translation, pitching and whirling motion of the rigid rod-are observed. Chaotic responses appear. near the fundamental principal resonance. In the chaotic oscillation of the rigid rod, translation, pitching and whirling motion appear irregularly. Typical chaos attractor on the Poincare section focused as a type of internal resonance.
