摘要
研究了弹性-粘弹性复合结构的动力学有限元模型的验证问题,提出了基于频率响应的模型验证方法。以粘弹材料夹芯复合板为研究对象,分别利用Matlab软件和Msc.Patran/Nastran软件进行有限元建模和频率响应分析,结果发现两种有限元模型的频率响应曲线非常吻合。这即验证了用Matlab软件建立的有限元模型的正确性,又表明该模型验证方法是可行的。
We propose the model verification method based on frequency response, study composite plates with cores of viscoelastic materials and carry out the FE modeling and frequency response analysis with Mat.lab and Msc. Patran/Nastran respectively. The frequency response curves derived from the above-mentioned two FE models are in good agreement. This verifies the correctness of the dynamics finite element model established through Mat.lab and the feasibility of this model verification method.
