概要

Shell Structures is often employed in mechanical structures. In the vibration transmission in curved shell, the flexural component of vibration energy is transformed into the extensional component and vice versa. A previous research reported that the extensional component fraction was higher for smaller curvature radius. The purpose of the present research is to investigate the behavior of both components of vibration energy flow in L-shaped model with small curvature radius by using Vibration Intensity (VI) method as a vibration energy flow visualization method and FEM analysis. Analysis results led to the suggestion that the extensional component fraction reach a maximum for smaller curvature radius.
