Abstract:

A considerable amount of Navy gear mounted aboard ship is held in position by flexible supports. These equipments have several modes of vibrations whose frequencies are easily determinable. The maximum displacements of these equipments with respect to their supports are of interest from the viewpoint of the suitability of the mounts in protecting the equipments from damage and also from the viewpoint of determining the relative intensities of shock at different locations on a ship. The lower modes of vibrations of the mounted equipments are generally in the range between 4 and 20 cps. As the response the response of a point on an equipment is considered to be the maximum displacement of that point with respect to its supports of an equipment is dependent on the type of mounting and the position of measurement is practical only to compare responses of similar equipment at given locations on the equipments, although sufficient data are included so that a more extensive analysis is possible.
