| 摘 要： | 对"X"形的中空复合材料的压缩性能进行测试,并根据其结构参数建立模型,使用ANSYS Workbench软件对建立出的模型进行静力学数值模拟分析,拟合出其压缩力学性能曲线,对比数值模拟结果与实验数据。结果表明:该复合材料压缩时芯材主要承受压缩载荷作用,更容易发生破坏,5 mm压缩变形时,最大压缩应力为475.25 MPa,最大压缩应变为3.9785%;建立出的复合材料结构模型压缩性能模拟结果与实验测试结果基本吻合,误差比例仅为(8.73±2.92)%,证明该模型具有一定的准确性。

| Abstract: | A 3D hollow composite with "X" core structure was designed and composited. Compression characteristic and property of 3D hollow composite were tested by Instron 3385H, and the stress-strain curve was obtained. According to structure parameter of the composite, the structural model was established. Static properties of the composite are simulated by ANSYS Workbench. Simulated result is compared to the testing result. The result showed that the main loads were supported by core structure of composite and the main failure occurred there. Simulated results approximately agree with the experimental, the models have certain veracity. |
