Konnard, E.H., "Some Casos of Vibration Forced by 

 Base Motions or by External Forces," DTMB Report 1394, 

 D>rombor 1960. 



This report gives formulas for the response of selected simple 

 vibratory systems to either forced motions of their supports or to extern 

 nal forces. The systems treated include a sprung mass, a sprung rotor, 

 a cantilever beam, and a general elastic system attached to a rigid base.

This report describes the physical characteristics, components 

 and instrumentation of the TMB Network Analyzer, and gives the layout 

 arrangement and some construction details. The procedure for setup, 

 calibration, and operation of the network analyzer is explained suffi- 

 ciently to permit the reader to utilize the facility.

Records of vertical and athwartships vibration were obtained 

 at the bow and at the stem, and of fore-and-aft vibration at the thrust 

 bearing and reduction gear housings.

A vibration-generator test was conducted on the starboard main 

 thrust bearings and their foundations aboard the USS FORRESTAL, 

 while the shafting was disconnected on both sides of the thrust bearings, 

 to determine experimentally the lowest resonance frequencies of these 

 systems with the aim of estimating the longitudinal spring constants of 

 the foundations, which were calculated to be 8. 2 x 10^ Ib/in. and 

 8.9 X 10^ lb/ in. 



Kron, G., **A Method of Solving Very Large Physical 

 Systems in Easy Stages,'* Proceedings of IfiE, April 1954. 



Physical systems with a very large number of variables (say 

 thousands) may be solved with digital computers by tearing the system 

 apart into a large number of small subdivisions. After solving each 

 subdivision, the partial solutions are interconnected by a set of trans- 

 formations so as to obtain the exact solution of the original system. 

 This paper illustrates the solution of Maxwell two-dimensional field- 

 equations by tearing their electric-circuit models apart into a convenient 

 number of subdivisions. 



Kron, G., "A Set of Principles to Interconnect the 

 Solutions of Physical Systems," Journal of Applied Physics, 

 Vol, 24, No, 8, August 1953. 



A set of principles and a systematic procedure are presented to 

 establish the exact solutions of very large and complicated physical 

 systems, without solving a large number of simultaneous equations and 

 without finding the inverse of large matrices. The procedure consists 

 of tearing the systan apart into smaller component systems. After 

 establishing and solving the equations of the component systems, the 

 component solutions themselves are interconnected to obtain outright, 

 by a set of transformations, the exact solution of the original system. 

 A simple boundary value problem is solved as an example. 



Kruszewski, E.T., "Effect of Transverse Shear and 

 Rotary Inertia on the Natural Frequency of a Uniform Beam," 

 NACA TN 1909, July 1949, 



A theoretical analysis of the effect of t 

 rotary inertia on the natural frequencies of a uniform beam is presented. 

 Frequency equations are derived for the cases of the cantilever beam, 

 and the free-free beam vibrating symetrically and anU-symetrically. 

 Numerical results are presented in the form of curves giving the fre- 

 quencies of the first three modes of the cantilever beam, and the first 

 six modes of the free-free beam,

This paper gives a unified treatment of the added mass for either 

 horizontal or vertical oscillations at high frequency in a free surface. 

 Some of the more obscure, but known results for vertical oscillation are 

 emphasized. The general results for horizontal vibrations presented 

 here are new.

 Solutions for the excitation forces on and transient response of a ship 

 subject to slam when certain basic data are obtained by computation 

 rather than by measurement.
