Characteristics of Ship Pedestal with Rigid Vibration Isolation Mass in Mid-Frequency Domain
摘要
Abstract
This paper aims to predict the vibration characteristics of rigid vibration isolation mass in the mid-frequency range. However, the calculation by FE method is quite time-consuming for low-frequency range, while by SEA method it cannot get exact results for mid-frequency range. A ship pedestal with rigid vibration isolation mass was studied by introducing the FE-SEA hybrid method with VA One software to deal with this problem. In the design of ship pedestal, a rigid vibration absorber was added, which positioned at the region of ship pedestal connected with the ship structure. The results show that for medium-high frequency structure noise, rigid vibration isolation mass can effectively reduce the vibration and sound radiation of the non-pressure hull, while in low frequency, vibration isolation effect of the mass is not so obvious.关键词
