摘　　要：建立了多扰源连续隔振浮筏系统的动力学模型，并考虑基础及浮筏弹性，推导了此类复杂耦合系统的动态特性方程及功率流表达式，从能量的观点揭示了连续隔振浮筏系统的隔振机理，并编制了相应计算软件，进行了数值计算及理论分析，揭示了连续隔振系统结构参数对其隔振性能的影响。A general dynamic model of a floating raft isolation system with multiple machines and supports is established. Considering the coupling of the foundation in high and basing on the mobility analysis of substructures, the expression of the power flow transmission spectrum of the finite continuous isolation system of asymmetry is derived. At the same time the mathematical calculation and analysis by figure are made to find the rules related to the isolation effect in the case of different parameters of the system.
