浮筏隔振系统的一种新隔振效果建模方法

A new modeling method for floating raft systems

提出了一种浮筏隔振系统的新建模方法,这种新的方法基于阻抗理论,避开了以往阻抗矩阵在筏架处理中的困难,应用这种新建模方法简单可行,并且计算得到的隔振效果可与实验的加速度振级落差相对应,具有很强的工程实用性。将应用方法得到的结果与试验进行对比,取得了较好的结果。这种方法可为浮筏隔振系统的进一步研究与工程应用提供更有利的模型。为了与以往的阻抗建模方法加以区别,最后将这种方法命名为"传递系数法"。

Based on the impedance theory,a new modeling method named as'MA-transfer coefficient method' was introduced for simulating a floating raft system.As avoiding difficults of building an impedance matrix of the raft frame,this method was more practical and feasible.Here,the effectiveness of the proposed method was verified by experi-mental data.The results indicated that this new method was feasible and very effective,and it could also provide a better model for optimization of a floating raft system.
