ON THE RESULTS OF SifiP VIBRATION

MEASUREMENTS CARRIED OUT

IN JAPAN.

Data Assembled for

THE SECOND INTERNATIONAL SifiP

STRUCTURES CONGRESS

(2)

ON TRE RESULTS OF SHIP VIBRATION MEASUREMENT CARRIED OUT IN JAPAN

The results of ship vibration measurements carried out in Japan have been summarized

in the form of fol1owig tables and figures.

1.

PARTICULARS OF SHIP.

( TABLE )

2.

RESONANCE CURVES OBTAINED FROM PROPELLING TESTS.

(

FIGURES )

"PARTICULARS OF SHIP" shows the general information on the type of test ship, its

propelling machinery, its construction, principal dimensions and the others.

In

this table, the shipbuilder's name is shown in abbreviated form, and full name

of

the builder corresponding to the abbreviated name is presented below.

"METHOD OF VIR.TIO1 MEAJREI'NT" shows the test condition of vessel, its loading

plan and the vibration exciter and vibrograph used in the experiments.

"ARRANGEMENT

OF MEASURED POINTS" shows the position of exciter and main engine, arid the

arrange-ment of measured points graphically.

'TEST RESULTS" is divided into two parts.

In part 1 the experimental results obtained

from vibration exciter tests are summarized.

"RESONANCE CURVES" shows only two curves measured at fore and after

_{ends for vertical}

and horizontal modes respectively.

_{And "MODE CURVES" shows the vibration profiles}

of the hull in the various modes of vibration at resonant frequencies.

_{These have}

been presented in non-dimensional form in which th

_{arhplitude at any position in the}

ship length is expressed as a ratio of the ordinate of exciting position.

In part 2

the experimental results obtained from propelling tests are summarized and in these

cases only resonance curves measured at fore and after ends are shown.

On a few

ships on which the exciter tests have not been carried out, only part 2 is shown in
