分岐をもった構造物の曲げ・ねじれ振動モード解析

抄録

We developed a theoretical model to calculate the bending-torsional vibration modes for branched structures like trees or plants. By considering the equation of motions and the boundary conditions, we obtained fundamental frequencies and amplitudes. As we compared the theoretical results with experiments, we confirmed reasonable agreement with each other. We also found an abnormal feature that two different eigen modes have similar modal shapes with different frequencies.
