摘要

以一对正齿轮为研究对象,基于接触力学和多体动力学理论,建立了正齿轮系统的接触动力学模型。该模型的特点是可以描述齿轮对的动态接触行为,齿轮对的啮合动作不再依赖于交替啮合的单齿和双齿的刚度模型,并且模型可以实时可视化。在建模过程中,首先要建立正齿轮的数学模型。然后建立正齿轮动态模型。最后,比较了三种方法(建议方法、叠加参数方法和实验方法)得到的振动响应。结果发现,与传统的叠加参数法相比,提议法与实验法的一致性更高,这验证了直齿轮传动接触动态模型的有效性。提出的模型和研究成果为齿轮系统的性能分析、优化设计和故障诊断等研究领域奠定了基础。

A novel method of modelling contact dynamics for spur gear transmission

Taking a pair of spur gears as the research object, a contact dynamic model of the spur gear system was established based on the theories of contact mechanics and multi-body dynamics. The characteristics of the model are such that it can describe the dynamic contact behavior of a gear pairs, the meshing action of gear pairs no longer depends on the stiffness model of single and double teeth undergoing alternating meshing, and the model can be visualized in real time. In the process of modelling, firstly, the mathematical model of spur gear is established. The spur gear dynamic model is then built. Finally, the vibration responses obtained by the three methods (the propose method, the lumped parameter method and the experimental method) are compared. It is found that the proposed method is more consistent with the experimental method than the traditional lumped parameter method, which verifies the validity of the contact dynamic model of spur gear transmission. The proposed model and research results lay the foundation for research fields such as performance analysis, design optimization and fault diagnosis of gear systems.
