Based on Hertz elastic contact theory, the contact mechanics model of two cosine wave is established. The mechanical characteristics of the model in the elastic, elastic-plastic, and plastic stages were studied. The influence of load on contact deformation and other characteristics is considered. The finite element method is used to analyze the deformation process of the model, and the results are compared with those of the mechanical model. The effects of amplitude and wavelength of cosine wave on its mechanical characteristics are discussed. The results show that the model reflects the relationship between the load and the mechanical characteristics of the model, and the difference of amplitude and wavelength will affect this characteristic.

基于赫兹弹性接触理论，建立了两个余弦波的接触力学模型。研究了模型在弹性、弹塑性和塑性阶段的力学特性。考虑了载荷对接触变形和其他特性的影响。采用有限元方法对模型的变形过程进行分析，并将结果与​​力学模型进行比较。讨论了余弦波的振幅和波长对其力学特性的影响。结果表明，模型反映了载荷与模型力学特性之间的关系，振幅和波长的差异会影响这一特性。
