概要:

application/pdf<br />Journal Article<br />Experimental results are presented for chaotic vibrations of a compressed buckled beam subjected to periodic lateral excitation. A thin duralumin beam coated with a sheet of thin vinyl was used as a test specimen. The beam was clamped at both ends to the base frame of an electromagnetic shaker. Initial axial displacement of the beam was controlled utilizing thermal elongation both of the beam and frame. Typical … responses of time history and the strange attractor of the chaotic vibration were observed near the frequency range of the fundamental resonant vibration. It is found that the correlation dimension of the strange attractor yields a value of d=3.8 under twice the axial displacement corresponding to buckling load. 続きを見る
