摘要: 由于材料的各向异性,与金属材料相比,玻纤增强复合材料可以通过相应的设计来更好地发挥其优势性能,复合材料机舱罩就是典型的例子。现有的机舱罩结构分析,多数只是对其承载力的检验。根据GL2010标准,利用SolidWorks建立机舱罩模型,在ANSYS中对其进行刚度和强度分析。根据分析结果,综合考虑制造的限制条件,如加强筋位置、分块、成本等因素,对加强筋的尺寸和整体蒙皮的厚度进行优化。优化后的分析结果表明,考虑制造限制条件的优化分析可以更好地满足工程对刚度的要求,是值得推荐的方法。

Abstract: Due to the anisotropy, compares to metal materials, GFRP composite can performance its advantages better by corresponding design. Composite nacelle is a typical example, the most structure analysis of it is only to check its bearing capacity. According to the Lloyd's GL2010 standard, the model was built by commercial soft SolidWorks, the stiffness and strength are calculated by finite element soft ANSYS. On the basis of the results, the design of the reinforced rib size and the skin thickness are optimized. Limiting condition of manufacture, location of stiffeners, block, cost and other requirements are all in the considering. The structure after optimized was analyzed, and the results show that the analysis and optimization result based on the manufacture, meets the engineering requirements for stiffness more, this worth to be recommended.

Key words: finite element, structure optimization, nacelle-cover
