本研究结合使用一个齿接触分析（TCA）模型的斜齿轮副连接与多方面的摩擦学模型，隐式耦合与多体动力学系统。降阶2-D弹流润滑剂（EHL）膜厚预测有利于估计的粘性和边界摩擦与格林伍德特里普粗糙模型，以及润滑磨损的方法。隐式的方法是用来捕捉齿轮齿上的磨损与齿轮微观几何形状的考虑。数值弹流润滑模型的使用提供了新的见解，耦合的演变磨损和动力学的效率和NVH在整个组件的生命周期。
This study combines the use of a Tooth Contact Analysis (TCA) model for helical gear pair conjunctions with a multifaceted tribological model, implicitly coupled with a multi-body dynamic system. A reduced order 2-D Elastohydrodynamic Lubricant (EHL) film thickness prediction facilitates the estimation of viscous and boundary friction with a Greenwood-Tripp asperity model, as well as a lubricated wear methodology. An implicit approach is used to capture progressing wear upon gear teeth with consideration of gear microgeometry. The use of the numerical EHL model gives new insights to the coupled evolution of wear and dynamics on efficiency and NVH throughout the component’s life cycle.
