Analysis on Influence of Tooth Surface Friction Factors in Gear Mesh Stiffness Modeling

齿轮系统在航空航天、汽车制造、农业机械等领域中应用广泛,能够实现复杂的动力传递与运动控制。齿轮啮合刚度及变化规律对齿轮系统动力学特性有直接影响。齿轮啮合过程中表面摩擦特性是影响齿面啮合刚度的主要因素之一,如何考虑摩擦因素,合理建立啮合面刚度模型长期以来一直是学术界研究的热点。分析目前主要的统计学模型、数值分析模型、分形接触理论模型的建模方式,为研究齿轮传动动力学建模提供参考。

Gear systems,widely used in aerospace,automotive manufacturing,agricultural machinery and other fields,can fulfill complex power transmission and motion control,and the gear meshing stiffness and variation law have a direct impact on the dynamic characteristics of gear systems.As the surface friction characteristics in the gear meshing process is one of the main factors affecting the tooth surface meshing stiffness,how to reasonably establish the meshing surface stiffness model considering the friction factor has long been a hot spot for academic research.This paper analyzespresentmain modeling approaches,such as statistical model,numerical analysis model and fractal contact theory model,which can be of reference for the study of gear transmission dynamics modeling.
