考虑到多尺度、多因素的影响，建立了具有突变区域的圆弧接触面之间的接触热传导分析模型。用W-M函数描述了接触面的分形特征。在考虑弹性、一次弹塑性、二次弹塑性和完全塑性变形过程的情况下，分析了四种状态下的接触面积和接触压力。为此，提出了一种分析计算TCC的方法。此外，还介绍了具有突变区域的圆弧接触面实验过程中TCC的计算方法。以此为研究对象，对具有突变区域的圆弧接触面的TCC进行了分析。可以观察到，在有突变区的接触面之间出现了局部高温。此外，温度、材料、粗糙度和接触压力对TCC的影响主要是通过改变实际接触面积来实现的。具有突变区的接触面上TCC的变化受接触物内部传热规律的影响。实验结果与仿真结果吻合较好，验证了理论建模的准确性。
A thermal contact conductance (TCC) analysis model between circular-arc contact surfaces with mutation area is established in view of multi-scale and multi factor effects. The fractal characteristics of contact surface is described by the W–M function. Contact area and contact pressure in four states are analyzed by considering elastic, first elastic–plastic, second elastic–plastic and complete plastic deformation processes when asperities contact. Therefore, a method for analyzing and calculating TCC is proposed. In addition, the calculation of TCC in the process of the experiment of circular-arc contact surfaces with mutation area is introduced. The TCC of circular-arc contact surfaces with mutation area is analyzed by the research object. It can be observed that local high temperature occurs between the contact surfaces with mutation area. In addition, the influence of temperature, material, roughness and contact pressure on TCC is mainly realized by changing the real contact area. The change of TCC on the contact surfaces with mutation area is affected by the internal heat transfer law of the contact object. The experimental results are in good agreement with the simulation results, which verifies the accuracy of the theoretical modeling.
