摘要

摘要: 用蒙特卡罗随机模拟法计算了固体接触界面间的接触热阻。取服从高斯分布的随机数作为粗糙峰高度，分别对每个粗糙峰计算出单点接触热阻，再并联所有单点接触热阻得到总的接触热阻。修正了积分法的理论结果且与发表的文献数据相符。

Abstract: Thermal resistance of contact interfaces of solids was simulated using Monte-Carlo method. Assuming that asperity heights obey Gauss distribution, the thermal resistance of contact surfaces was obtained by summarizing all the single point contact thermal resistances calculated. The results simulated using Monte-Carlo method are in better agreement with experimental data, relative to using normal integral method.
