Free vibration of curved beam with varying curvature and taper ratio

الملخص EN

In this study free vibration of uniform curved beam with varying curvature and taper thickness between the root and tip of beam are investigated by using the finite element method using (Ansys 9.0).

Nine models from curved beam all models have four cases have different in taper ratio for the same curvature are studied.

The results obtained from this study are compared with the results of other investigators in existing literature for the fundamental natural frequency and it's found from this results the natural frequency increase with increasing the taper ratio and curvature for the servel models from curved beams.

Finally the effect of the taper ratio and curvature on the natural frequency are shown in graphics.
