A Numerical Analysis on the ascoutic radiation efficiency of a stiffend cylindrical structure in underwater under multi-excitation
- 발행 : 2014.10.29
초록
This study is on acoustic radiation efficiency of a tiffened cylindrical model in water-multi-excitation with phase difference using commercial numerical program ABAQUS and SYSNOISE. When the stiffened cylindrical model is under multi-excitation with phase difference, the surface vibration field is variated with phase difference of excitation. By this different surface vibration field, the acoustic radiation efficiency is also variated with phase difference of excitation.
