| Research Abstract |
In this study, nonlinear vibration characteristics of 2-dimensional fractal trees were discussed through vibration tests, measurement of the resonance phenomena, CAE analyses and numerical simulations using well-known software packages. Especially 3-dimensional CAD models and test pieces for the binary trees and the ternary trees were produced.
The binary trees showed the behaviors like dynamic vibration absorbers. The complicated resonance phenomena of the ternary trees occurred in vibration tests but not in CAE analyses. Then the natural modes were clarified by using a high speed camera.
