摘要
通过有限次数的实验结合模型确认方法对数值模型的可靠性进行验证,建立了考虑参数不确定性碳纤维复合材料冲击响应的数值模型确认方法;以碳纤维增强复合材料(T700/X105)试件沿厚度方向受到冲击的数值模型确认过程为例,基于累积分布函数的模型确认准则,对三种不同工况下碳纤维复合材料的数值模型进行了确认分析,验证了所建立的模型确认方法的有效性,为具有不确定性的碳纤维复合材料的数值模型确认提供新的思路和参考方案。
The reliability of the numerical model is verified by the limited experiments combined with the model validation method. A numerical model validation method for the impact response of carbon fiber composite with uncertain parameters is established. Taking the numerical model validation process for the impact of carbon fiber reinforced composite samples （T700/X105） along the thickness direction as an example. Based on the cumulative distribution function model validation criteria, the analysis for numerical model validation of carbon fiber composite under three different conditions is conducted and the validity of the established model validation method is verified. It offers new thought and reference for numerical model validation of carbon fiber composite with uncertainty.
