Natural vibration analysis of 2.5D resin⁃based braided composite plates

  • 摘要:

    开展2.5维T800碳纤维/BMP350聚酰亚胺树脂编织复合材料平板结构固有振动特性的仿真分析与试验研究。首先,分别采用多尺度分析方法和细观尺度有限元分析方法预测复合材料悬臂平板的固有振动特性。其次,开展了复合材料悬臂平板的模态试验,获取其固有振动特性的实测数据。与试验结果对比,仿真预测固有频率最大误差在10%以内,验证了上述两种固有振动分析方法的有效性,可为后续2.5维树脂基编织复合材料叶片的动力学性能分析与设计研究提供参考。
