Vibration control of shallow shell structures using a shell-type dynamic vibration absorber
In this study, a new shell-type dynamic vibration absorber is presented for suppressing several modes of vibration of the shallow shell (main shell) under harmonic load. It consists of a shallow shell (the dynamic absorbing shell), under the same boundary condition and with the same shape as those of the main shell, with connecting springs and dampers in the vertical direction between the main and dynamic absorbing shells. Formulae for an approximate tuning method for the shell-type dynamic absorber are also presented using the optimum tuning method for a dynamic absorber in the two-degree-of-freedom system, obtained by the Den Hartog method. Subsequently, numerical calculations are presented which demonstrate the usefulness of the shell-type dynamic vibration absorbers.
