【摘要】:由于材料的各向異性,與金屬材料相比,玻纖增強復合材料可以通過相應的設計來更好地發(fā)揮其優(yōu)勢性能,復合材料機艙罩就是典型的例子,F(xiàn)有的機艙罩結構分析,多數(shù)只是對其承載力的檢驗。根據(jù)GL2010標準,利用Solid Works建立機艙罩模型,在ANSYS中對其進行剛度和強度分析。根據(jù)分析結果,綜合考慮制造的限制條件,如加強筋位置、分塊、成本等因素,對加強筋的尺寸和整體蒙皮的厚度進行優(yōu)化。優(yōu)化后的分析結果表明,考慮制造限制條件的優(yōu)化分析可以更好地滿足工程對剛度的要求,是值得推薦的方法。
[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.
