摘要
齿轮系统作为现代机械传动系统的重要组成部分,广泛应用于工业、能源、航空航天等诸多领域。由于齿轮系统的工作环境复杂,其动力学行为通常受到多种非线性因素的影响,如摩擦、齿隙、时变刚度等,导致其表现出丰富的非线性动力学特性。近年来,随着非线性动力学理论的发展,学者们针对齿轮系统中的非线性行为开展了大量研究,提出了多种非线性动力学模型和分析方法,用于揭示齿轮系统的混沌、分岔等复杂行为。本文系统回顾了齿轮系统非线性动力学的研究进展,涵盖了非线性建模方法、非线性动力学行为特征分析、数值模拟技术及其在齿轮系统故障诊断中的应用。最后,本文总结了当前研究的挑战与不足,并展望了齿轮系统非线性动力学未来的研究方向,以期为齿轮系统的优化设计、故障诊断与健康监测提供理论支撑。
Gear systems,as an important part of modern mechanical transmission systems,are widely used in many fields such as industry,energy,aviation and aerospace,and so on.Due to the complex working environment of gear system,its dynamic behavior is usually affected by a variety of nonlinear factors,such as friction,backlash,time-varying stiffness,etc.,which leads to its expression of rich nonlinear dynamics characteristics.In recent years,with the development of nonlinear dynamics theory,scholars have carried out a large number of studies on the nonlinear behaviors in gear systems,and proposed a variety of nonlinear dynamics models and analytical methods,which are used to reveal the complex behaviors of the gear systems such as chaos and bifurcation.This paper systematically reviews the research progress of nonlinear dynamics in gear systems,covering nonlinear modeling methods,characterization of nonlinear dynamics behaviors,numerical simulation techniques and their applications in fault diagnosis of gear systems.Finally,this paper summarizes the challenges and shortcomings of the current research and looks forward to the future research direction of nonlinear dynamics of gear systems,with a view to providing theoretical support for the optimal design,fault diagnosis and health monitoring of gear systems.
