The paper presents study of the dynamic aspects of the multiply bellows with elastically restrained ends and under rotatory inertia. The influence of rotational restraint and internal pressure loading on dynamic response of such bellows configuration has been attempted here. An attempt has been made here to establish relations that are simple and compatible in computing the frequency of bellows. The Rayleigh Quotient method is used for this purpose. The coupled responses obtained are compared with exact analysis for multiply configuration. Two cases are considered - bellows having same material and different materials for plies. The approximate natural frequency for multiply Bellows is derived using the Rayleigh-Ritz method. The influence of rotational restraint at either end is studied and the results are presented. It is found that the first mode frequency of multiply bellows is nearly 50% away than the exact and is supposed to be quite significant. Though, the method can be used as first approximation by the designers, it is found that it is not a reliable one in comparison with the exact method. It is found that the frequency of multiply bellows of for n321 and n400 for the plies is same.
