ON TRANSIENT VIBRATION OF STERN BODY STRUCTURES OF CAR FERRY DUE TO WAVE IMPACT ON AFT BOTTOM

In the present paper, the stern body structure of a 151 m long car ferry was simplified into a three dimensional frame work constructed by three equivalent transverse rings and six equivalent longitudinal members. The wave impact pressure on aft bottom due to relative motion between aft body and wave surface was estimated by Wagner's theory. The calculation of the transient vibratory response was made at Froude number 0.15 in regular head sea with wave length of 147 m and wave height of 7 m. Order from NSFI as No. 19093.
