摘　　要：对于简单的磁流变液夹层结构可以通过理论推导等方法得到结构的固有频率和损耗因子,但是对于大型的复杂磁流变夹层结构难以处理,而实验研究受实验条件影响很大,能够在实验中实现的荷载状态也很有限,因此利用现有大型有限元分析软件进行模拟计算是很有必要的。本文先提出了四边简支条件下磁流变液矩形夹层板结构固有频率与损耗因子的理论计算方法,其次基于ANSYS提出几种模拟磁流变液夹层板动力特性的方法,并与理论解进行对比,从而获得模拟最佳的单元组合模型。For the simple MRF rectangular sandwich structure, the natural frequency and loss factor can be obtained by theoretical derivation method. But for the large complex MRF sandwich structure is difficult to deal with and the experimental study is greatly affected by the experimental conditions. What＇s more, the experiment load condition is also very limited, so the use of the finite element analysis software to simulation is necessary. In this paper, a theoretical calculation method of MRF rectangular sandwich plate simply supported on four edges was proposed to calculate Natural Frequency and loss factor. Based on the ANSYS, this paper proposes several methods to simulate MRF rectangular sandwich plate, and obtains the best modular model by compare with the theoretical result.
