摘要
利用有限元方法对一种特殊形状的复合材料旋转壳在轴压工况和内压工况下的强度进行了计算分析 ,揭示了应力分布特点 ,确定了破坏区域和方式 ,预报了模型的破坏载荷值。同时对其在轴压、外压和轴 /外压工况下的稳定性也进行了分析计算。对内压、轴压下的强度和轴 /外压下的稳定性进行了实验研究。
The paper presents a finite element model for strength analyses of a rotational composite shell under axial compression and internal pressure. Characteristics of stress distribution and locations and loads of failure are determined according to the model. The model is also developed to calculate stability of the shell under axial compression, external pressure and the combination of axial compression and external pressure. Experiments are completed for studying the strength of the shell under axial compression and internal pressure and the stability of the shell under the combination of axial compression and external pressure.
