摘要
Abstract
The dynamic characteristic of the raft frame is an important factor affecting the vibration isolation performance of the floating raft system. In this paper, a new type of discontinuous ribbed raft frame structure is put forward. A complete three-dimensional model of the raft system is established based on the finite element analysis code Ansys to analyze its dynamic characteristics. The vibration isolation performance of the discontinuous ribbed raft frame is analyzed using the power flow evaluation method and compared with that of the traditional floating raft. The research shows that the vibration isolation performance of the discontinuous ribbed raft frame system is superior especially in the middle and high frequency ranges.关键词
