Abstract
In order to reduce the structure-borne noise of naval-vessel onboard equipment to meet imposed standards, the equipment exciting force should be restricted and additional anti-vibration devices such as resilient mounts and bellows should be applied. Since the structure-borne noise is dependent on the design of the equipment base, the realization of a low-vibration base design is important. In this study, a typical pump base is optimized using Design of experiment (DOE) and Computer-aided engineering (CAE) techniques, in order to minimize the vibration transferred from the equipment base to the floor. In addition, a sandwich panel consisting of a steel plate and rubber material is applied to the pump base between an anti-vibration mount and the base, so as to reduce the vibration transferred from the pump using the double-mounting-system principle. Consequently, the structure-borne noise reduction achieved by applying the proposed base design is verified via experiment.
