一种考虑侧接触切向滑动的微凸体弹塑性变形传热模型

摘要/Abstract

摘要：

为了准确预测热成形中的界面传热特性，提出了一种考虑侧接触切向滑动的微凸体弹塑性变形传热模型.利用材料在塑性变形时的体积守恒原理，对单对侧接触微凸体在切向滑动时的传热模型进行分析，基于微凸体弹塑性变形理论，分析了粗糙表面上单对球形微凸体在侧接触切向滑动时的变形模式与接触压力的关系，推导出单对球形微凸体在弹塑性变形时的传热模型，并将推导模型与有限元法(FEM)的模拟结果进行比较，以验证其准确性.结果表明，所提出的模型在完全塑性接触条件下对接触压力的预测结果与FEM分析的结果接近.随着接触压力增大，侧接触微凸体的传热系数增大；随着滑动位移增大，产生的摩擦热增加，侧接触微凸体的传热系数增大.
