| 摘 要： | 介绍了一种随机表面间接触热阻的计算方法, 即将接触点简化为圆盘接触模型计算单点接触热阻, 用计数函数的方法确定接触点的分布函数, 最终得到接触热阻随接触表面所受挤压应力变化的半经验公式, 本文还依据实验数据拟合得出一种实验条件下的半经验公式, 并对此实验拟合曲线的分散度做了分析。

| Abstract: | A method is provided for calculation of contact heat resistance between two contacting surfaces.The contact heat conductance was derived for a single contact spot of a simplified disk contact model.The distribution function of contact spots can be solved by using the method of counting functionals.As a result,an empiric formula of the contact heat resistance with the fluctuations of extruding stress is derived. |
