摘要
Abstract
Floating raft vibration isolation system is the most widely used vibration isolation method in ships. Multiple power machines are installed on the same raft through the upper vibration isolators. The raft is connected to the hull base through the lower vibration isolators. In this paper, a marine floating raft vibration isolation device is taken as the research object. Based on the raft structural optimization, three schemes of raft improvement are proposed. They are to add the inclined plate, to add the discontinuous reinforcing rib and to add the rib plate, respectively. The vibration isolation effects of different schemes are calculated and analyzed. The results show that the vibration isolation performance of the raft structure is improved obviously, and the vibration isolation performance improvement of the last scheme is the most prominent.关键词
