Finite cylindrical shells with stiffened ribs are major structure of cabin on the submerged or underwater vehicles. This paper aims to probe into the feasibility of sound radiation simulation of underwater structure based on ABAQUS. ABAQUS is used to compute and analysis the underwater sound radiation rule of double cylindrical shell structure. And the computation data agrees with the experimental data basically. Adopting boundary impedance technique and acoustics IEM technique to simulation infinite flow field is feasible, and adopting acoustics IEM technique has much better performance. Boundary impedance technique is promoted for the concerning of accuracy. The results indicate that ABAQUS is appropriate to solve underwater sound radiation problem and it can satisfy the requirement of project application, which provides a new analysis method.
