摘要：

A turbomachinery blade is treated as a cylindrical thin panel with curvature and twist. The non-linear strain-displacement relations of the model are derived based on the general thin shell theory, and a numerical method for analysing the free vibrations of curved and twisted cylindrical thin panels is presented by means of the principle of virtual work for the free vibration using the Rayleigh-Ritz method, assuming two dimensional polynomial functions as displacement functions. It is shown that the method is effective in solving free vibration problems for cylindrical thin panels with curvature and twist by comparing the numerical results with previous results. The effects of curvature and twist on the frequency parameters and mode shapes are also discussed. (C) 1999 Academic Press.
