复合材料稳定翼有限元分析方法对比研究

对于某夹芯复合材料稳定翼,针对其复杂的外形和特殊的内部结构,分别采用两种建模方案对其进行ABAQUS非线性有限元分析,计算了稳定翼在深水静压载荷作用下的变形和干模态固有振型.通过对计算结果的分析与比较,发现方案二比方案一更合理、有效.

Comparative study of finite element analysis method to stabilizer-wing made with advanced composite material

This paper use two methods to establish Finite-Element-Method models to analyse a sandwich stabilizer-wing. This wing has a complex outer-shape and special interal structure. Furthermore, the main characteristics of these two different methods are : (1) the solid element is adopted for FRP surface of sandwich;(2) the shell element is adopted for FRP surface of sandwich. By using these different models and ABAQUS nonlinear Finite Element Method software, the deformation of the sandwich stabilizer-wing under high water pressure is calculated and the natural vibration mode of this wing is also gained. After the analysis and comparison of these results, it is found that method (2) is more reasonable and effective than method (1).
