【摘要】 应用薄片模型中的串联模型和并联模型,将矩形树脂槽和树脂槽间的泡沫看作是综合两者的组合模型,利用有限元软件ANSYS对该组合模型建立物理模型,进而模拟计算出其基本力学参数。再将该组合模型作为复合材料夹芯板的芯材的一部分,应用ANSYS建立含有两层不同性能芯材的夹芯板的模型,模拟整体复合材料夹芯板的弯曲性能。利用这种方法,模拟分析了随着开槽深度的增加,复合材料夹芯板抗弯性能的提高。本文为下一步模拟计算含楔形、拱形、开孔等异性槽的复合材料夹芯板的力学性能提供了一种参考方法,有利于优化开槽设计,确定最佳的开槽形式。更多还原

【Abstract】 This paper combines the resin and the foam between the resin as a combination model combining of the series model and parallel model in sheet models.Uses the finite element software ANSYS building a physical model of the combination model and simulated it’s basic mechanical parameters.Regards the combination model as part of the core of the sandwich panels.Utilizes ANSYS building the model of the panels with two cores of different properties,and simulating the flexural properties of the overall composite sandwich panels.By using this method,we can see that the flexural properties of the composite sandwich panel increase with the creasing of the depth of the slots.The article provides a reference method for calculating the mechanical properties of the composite sandwich panels with wedge,arched and other heterosexual slots.The paper helps to optimize slotted design and determine the best form of slotting.更多还原
