【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Solid Works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]:Because of the anisotropy of the material, the glass fiber reinforced composite material can give better play to its superior performance through the corresponding design compared with the metal material. The composite cabin cover is a typical example. Most of the existing analysis of cabin hood structure is only a test of its bearing capacity. According to GL2010 standard, the model of engine room hood is established by solid works, and its stiffness and strength are analyzed in ANSYS. According to the results of the analysis, the size of the reinforcement and the thickness of the whole skin are optimized by taking into account the manufacturing constraints, such as the position, block and cost of the reinforcement. The results of optimization analysis show that the optimal analysis considering manufacturing constraints can better meet the requirements of engineering stiffness and is a recommended method.
