A VIBRATION ANALYSIS OF GRILLAGE BEAMS

A simple method of analysis of the vibration characteristics of grillage beams is introduced which is proven to be extremely simple to use. Irregularities in structural details of many types are admissible. Hence, the method is particularly applicable to ship structures. The natural frequency is shown to be a solution of a transcendental frequency equation. By application of the Rayleigh-Ritz method, approximate natural frequencies can be derived, however. Numerical results are given which indicate that accurate results are obtained in this manner for the lower frequencies of concern.
