Abstract:

The tactical implications of submarine acoustic radiation and UNDEX- survivability have motivated the development of an advanced machinery cradle which will provide shock and vibration isolation of the submarine internals, thereby minimizing the resulting acoustic radiation. The cradle space frame must be designed and optimized for both minimum shockvibration bi-directional transmissibility and minimum total cradle weight. Frequency domain structural synthesis structural modification and substructure coupling, is applied to the cradle design. The method addresses static and complex dynamic problems in structural design analysis, and allows the direct analytic treatment of specialized equipment. frequency-dependent viscoelastic isolators.
