摘要

本文采用有限元模型研究了接触面曲率对不同切向载荷下摩擦响应的影响。结果表明，接触面几何形状会影响接触面处的接触力，并通过接触力的非定常分布减小摩擦效应。研究了摩擦效应、激励和接触面形状之间的关系，揭示了摩擦与曲率之间的线性反比关系。这些发现提供了对弹性体之间摩擦相互作用的全面理解，并强调了曲率作为调节摩擦效应的设计参数的作用。

Influence of contact curvature on frictional energy dissipation under varying tangential loads

This study investigates the effect of contact surface curvatures on the friction response under varying tangential loadings using a finite element (FE) model. The results showed that the geometry of the surface influences the contact force at the interface and reduces the friction effect through an unsteady distribution of the contact force. The relationship between the friction effect, excitation, and contact surface shape was also examined, revealing a linear inverse relationship between the friction and curvature. The findings provide a comprehensive understanding of the frictional interactions between elastic bodies and highlight the role of curvature as a design parameter for regulating the friction effect.
