Abstract:

The dynamic behavior of a symmetrically stiffened cylinder was analytically and experimentally studied to determine the effects of a longitudinal steady state driving force on the radial velocity of the shell. This study showed that lobar modes are excited by a longitudinal excitation and compare well with the theoretical predictions. Also, four cases of unsymmetrically stiffened cylinders were analytically studied by the lumped mass mass technique to determine the effects of deep frames. The fundamental frequency is reduced as much as 20 by the added deep frames stiffness and mass, and all of the mode shapes are irregular due to the influence of the frames. Author
