The structural and acoustic responses of a submarine under harmonic force excitation are
presented. The submarine hull is modelled as a cylindrical shell with internal bulkheads and …

This paper studies the low frequency vibrational behaviour and radiated sound of a
submarine hull under axial excitation. The submarine is modelled as a fluid-loaded …

The vibro-acoustic response of ring stiffened cylindrical shells with internal bulkheads under
forced excitation is presented. The numerical analysis model is established using the Jacobi …

Active control is effective in reducing the low-frequency vibration and acoustic radiation of
the stern system of an underwater vehicle. This paper theoretically investigates the reduction …

A theoretical analysis of the active control of low-frequency radiated pressure from
submarine hulls is presented. Two typical hull models are examined in this paper. Each …

Several decades after the development of acoustic stealth technology for ships, there
remains an urgent necessity to reduce low frequency structural and acoustic response due …

This paper describes the development of a numerical model to predict the vibro-acoustic
behavior of an externally fluid loaded shell with non-uniformly space stiffeners and …

An active multi-strut assembly is used to attenuate vibration transmission from the shaft to
the hull of underwater vehicles induced by the propeller forces. The active assembly with …

This paper presents an active control method for reducing the lateral vibration transmission
in a shaft-hull coupled system of submerged vehicles under the excitation of propeller …

For thin elastic structures submerged in heavy fluid, eg, water, a strong interaction between
the structural domain and the fluid domain occurs and significantly alters the …
