Meshless Model and Application for Heat Transfer of Engine Composite Materials Connecting Rod

  • 摘要: 利用无网格伽辽金法(Element-free galerkin,EFG)建立了发动机复合材料连杆的传热计算模型,推导了正交各向异性结构的无网格法传热控制方程,通过复合材料平板验证了该模型对混合边界条件传热问题有很好的适应性。利用EFG法计算了不同各向异性因子的复合材料连杆的温度场,并讨论了EFG节点数对精度的影响。结果表明,EFG法的温度计算精度比有限元法高,且各向异性因子小于1时能较好地改善连杆小头的温度场分布,连杆设计时宜选择横向导热系数比纵向大的复合材料。
