摘要
本文以开孔平板的单向拉伸和销栓挤压为应用背景,提出了一种面向应用的复合材料构件CAE/CAM一体化纤维铺放路径优化设计方法。利用ANSYS有限元分析工具,根据复合材料构件的受力分析,按构件的主应力形式选用纤维类型、按主应力方向优化设计构件的纤维铺放路径,并按主应力大小设计纤维铺放密度,以充分发挥纤维复合材料性能,提高构件的强度和刚度。详细讨论了应用该方法所涉及的建模、网格划分、理论铺放路径生成和实际铺放路径修正等相关技术。
An optimization method of fiber placement path for composite components by means of CAE/CAM integration is presented in this paper, which is illustrated by a tensile plate with an open hole and a pin-loaded hole. By using ANSYS, the stress trajectories are determined with FE computing under application conditions, and the fiber is arranged in a way that they follow the stress field in the composite component in order to fully exploit fiber performance and increase the strength or stiffness. Related technologies are also discussed in detail, including modeling and meshing for FEA and arrangement of fiber placement path.
