摘要
面对碳纤维复合材料铺层角度各不相同,成型后的力学性能呈现各向异性的特点,通过异性材料正交对称平面的方法,对材料进行分解和简化,将主要各向异性的力学指标变换为正交异性指标.同时以碳纤维复合材料实物样件的力学试验为基础,提高软件疲劳仿真与实际设备物理状态的匹配程度,并以碳纤维复合材料设备为样本,进行了软件疲劳仿真和分析.
Abstract
In face of the fact that the layup angles of carbon fiber composites are different and the mechanical properties after molding are anisotropic,the decomposition of the materials by the method of orthogonal symmetry plane of anisotropic materials is simplified,the materials index of the main anisotropy is changed to the orthotropic index.The matching degree between the software fatigue simulation and the actual state of the equipment is im-proved based on the physical mechanical testing of the carbon fiber composite material sample and certain equip-ment is taken as a sample to carry out the software fatigue simulation and analysis.
