Calculation of Rigid-Body Motion of Integrated Raft Isolation System

摘要：

　　Integrated raft isolation system (IRIS) has some advantages over raft system of much smaller scale,such as higher isolation efficiency,less use of elastic couplings,etc.But the calculation of IRISs dynamic characteristics is complex.Finite element method usually adopted by raft designers is inefficient due to the iterative nature of design process.In this paper a six-degree-of-freedom rigid-body motion model is presented to calculate the static,quasi-static and rigid-body mode behavior of IRIS.The model is especially suitable to compare different design schemes and select out feasible ones efficiently at the initial design stage of IRIS.
