Ceramic materials, with their excellent properties, have been widely used in the engineering field. With the ceramic surface as the research object, the properties of elastic contact of ceramic surfaces are studied using the numerical simulation calculation method. In this paper, uniform experimental design is carried out with topography parameters, external load, and material property parameters, which have a direct impact on the surface contact; a numerical calculation model is established and a series of simulation experiments is carried out on the contact of asperities on the ceramic surface, which not only intuitively shows the contact behavior of asperities on the ceramic surface, but also obtains the contact parameters of the surface. Then, the numerical simulation results are compared with those of G-W model, which proves the feasibility of the numerical simulation calculation and shows that the numerical simulation model established in this paper is more in line with the engineering practice than the G-W model. Through the regression analysis of the simulation results, the analytical calculation model between the surface contact parameters and the influencing factors is established, which provides references for quantitative analysis and characterization of contact properties related to the material surface.

陶瓷材料以其优异的性能已广泛应用于工程领域。以陶瓷表面为研究对象，采用数值模拟计算方法研究了陶瓷表面的弹性接触性能。本文对形貌参数，外部载荷和材料特性参数进行了统一的实验设计，这些参数直接影响表面接触。建立了数值计算模型，并对粗糙面在陶瓷表面的接触进行了一系列的模拟实验，不仅直观地显示了粗糙面在陶瓷表面的接触行为，而且获得了表面的接触参数。然后，将数值模拟结果与GW模型的数值模拟结果进行比较，证明了数值模拟计算的可行性，表明本文建立的数值模拟模型比GW模型更符合工程实践。通过对模拟结果的回归分析，建立了表面接触参数与影响因素之间的解析计算模型，为定量分析和表征与材料表面相关的接触特性提供了参考。
