Adnms, Emily J. and Welch, A.R., "Calculations of 

 Floxural Critical Frequencies of Ship Hulls by Prohl's 

 Method," DTMB Report 582, July 1947. 



This report extends Prohl's method for the calculation of the 

 flexural critical frequencies of flexible rotors to the calculation of the 

 llexural critical frequencies of ship hulls. The method is simplified and 

 set up so that the computations can be readily made with a punch-card 



Breslin, J. P. and Tsakonas, S,, "Marine Propeller 

 Pressure Field Due to Loading and Thickness Effects," 

 SNAME, Vol. 67, p. 386, 1959. 



This paper deals with the total field produced by blade-thicknes 

 effects as well as that due to loading. This is a new treatment of the 

 pressure field. It has produced closed form answers in terms of 

 tabulated elliptic integrals to replace the numerical harmonic analysis 

 formerly employed. 



Adams, Emily J., "The Steady-State Response of a 

 Ship's Hull to a Simple Harmonic Driving Force Computed 

 hy a Digital Process," DTMB Report 715, May 1950. 



A numerical method of finding the steady-staf^ response of the 

 hull of a ship to a sinusoidal driving force is described. Results of 

 calculations for the vertical flexural vibration of the USS NIAGARA 

 (APA 87) are given and compared with experimental data. It is also 

 shown that the vibration of the hull at a frequency other than one of the 

 natural mode frequencies may be calculated as the sum of the vibrations 

 of the natural modes compounded by a nor 



Baier, L.A. and Ormondroyd, J., "Vibration at Stern of 

 Single-Screw Vessels," SNAME Transactions, Vol, 60, 

 p. 10, 1952. 



This paper is concerned with the problem and elimination of 

 faintail vibration as experienced on bulk carriers operating on the 

 Great Lakes; however, it is thought that the solutions evolved are 



applicable to (

Buchmann, E. and McConnel, J.D., ^'Environmental 

 Conditions of Ship Motions and Vibrations for Design of 

 Radar Systems on Destroyers and Aircraft Carriers,'* 

 DTMB Report 1298, July 1959. 



Rigid-body motions and vibrations measured over « long period 

 of time and a wide range of operating conditions, are used to c)i 

 the environmental conditions of vibration and ship motion for u 

 design of radar installations. Extreme values for ship motions 

 seas are predicted. Application of the data to design problems are 

 discussed. 



Gatewood, , W., "The Period of Vibration of Steam 

 Vessels," SNAME, Vol. 23, p.ll9, 1915. 



The basis of this paper is that, by changini^ the loading of the 

 vessel where the vessel is considered to act like a beam, the period of 

 vibration is automatically changed. Computations are given for the 

 periods of vibration when the ship is represented as a beam. 



Jasper, N.H., *'A Design Approach to the Problem of 

 Critical Whirling Speeds of Shaft-Disk Systems," DTMB 

 Report 890, December 1954. 



The problem of resonant whirling of propeller-shaft systems is 

 discussed with special emphasis on those factors determinning the 

 critical speeds. Several methods for computing the natural whirling 

 frequencies of propeller-shaft systems are presented and discussed. 

 Computed and experimentally determined natural frequencies are 

 compared.

 1956. 



This research attempts to show that by utilization of statistical 

 methods, it is possible to describe and predict service conditions for 

 ships ia an orderly and relatively simple manner despite the general 

 complexities of the problem. 



Wave-induced motions and stresses in ships obtained under a 

 wide range of operating conditions are presented for seven different'
