The face gear is a widely researched new transmission mechanism. This mechanism can be widely used in the special transmission area, especially in the field of aviation. Since the contour of the face gear is complex, it cannot be modeled directly. The most common method of mechanical transmission is that of gear transmission, in which the tooth surfaces contact each other to transmit power, although the friction mechanism between the driving gear and the driven gear remains complicated. The friction between the teeth has a direct impact on the vibration and noise in the transmission process. Therefore, it is important to research on the accurate modeling of the three-dimensional (3D) model of the face gear and to study the nonlinear dynamics of the tooth surface friction excitation on the gear transmission system.

高性能端面齿轮复杂齿面微形貌和多自由度非线性摩擦动力学的精确建模

端面齿轮是一种被广泛研究的新型传动机构。该机构可广泛应用于特殊传动领域，特别是航空领域。由于面齿轮的轮廓比较复杂，无法直接建模。机械传动最常见的方法是齿轮传动，尽管主动齿轮和从动齿轮之间的摩擦机制仍然很复杂，但齿面相互接触来传递动力。齿间的摩擦力对传动过程中的振动和噪声有直接影响。因此，研究端面齿轮三维（3D）模型的精确建模以及研究齿轮传动系统中齿面摩擦激励的非线性动力学具有重要意义。
