Approximation for the Effect of Twist on the Vibration of a Turbine Blade*
Published online by Cambridge University Press: 07 June 2016
Summary
Modern turbine blades are generally twisted about their axes, the shape resembling that of a helicoid. This makes the determination of their overtone frequencies much more difficult. The equations governing the flexural vibrations may be obtained from the Clebsch-Kirchhoff theory for rods which are naturally twisted. By using these equations, this paper considers a first-order approximation for the effect of uniform twist.
