摘要
应用有限差分和传热学的基本原理,建立了聚甲醛钢背铜塑三层自润滑复合材料端面试样的温度场分析模型和计算方法,推导出了一种二维离散有限元空间的稳态温度差分方程。在端面摩擦边界条件下使用该方法给出了试样的温度场分布,其结果与试验结果吻合较好,表明该模型能满足模拟钢背铜塑自润滑材料端面试样的摩擦热分析要求。
A numerical method and temperature analysis model is developed based on heat transfer theory and finite difference method for the frictional heat problems of the three - layer self - lubricated composite material of steel - substrate with two layers of copper and polyoxymethylene (POM), and a steady- state temperature differential equation of the two - dimensional finite dement space diseretization is educed. The two - dimensional temperature field of the sample is given using the method, which was compared with the restrlt of experimentation, and showed that the model can satisfy the simulating demands of friction - reduced heat analysis in ease of tri - laminated self - lubricated composites with steel substrate.
