摘要：

The differential equations governing free, out-of-plane vibrations of non-circular curved beams resting on Pasternak-type foundations are derived and solved numerically. The lowest three natural frequencies are calculated for the parabolic shapes with hinged-hinged and clamped-clamped end constraints. The effects of various system parameters on natural frequencies are investigated.
