本文提出了一种复合材料纤维排列的随机结构建模方法。该方法使得对纤维束中纤维单丝层面的随机排列结构对渗透性和流动特性的影响等研究成为可能。本文考虑了四个参数,包括三个微观结构参数:纤维束中域的边长L、纤维单丝半径值波动范围△R、纤维单丝间最小间距δmin和一个宏观参数:孔隙率ε。对纤维随机排列的多孔介质横向饱和流动进行了有限元分析,并采用Morris全局灵敏度分析(GSA)方法,研究了四个参数对渗透率的影响。结果表明宏观参数气孔率ε对纤维增强材料的渗透性能影响最大。 Read More
确保电池模组的温度均匀性是电池热管理系统设计中的重要工作。本文设计了一种具有不同电池分布策略的锂离子圆柱电池模块,以提高其均匀性。建立了3维传热—1维电化学耦合有限元模型,对电池模块的布置进行了分析和优化。基于等差数列和等比数列来排列电池的间隔。发现在电池之间改变间隔的布置是改善电池模组内电芯均匀性的有效方式,尤其是等差数列布置。电池模块的最大温差随着初始间距的增加而减小。电池初始间距达到5.5mm时,电池模块的最大温差可降低13%,最大电压差可降至2.5 mV。具有等差数列布置的电池模块内部的温度和放电的均匀性优于等比数列布置 ... Read More
