【摘要】：齿轮系统应用广泛,并在风力发电、航空航天、汽车和盾构机等机械设备中发挥关键作用。其动力学特性的优劣将直接影响设备整机的工作性能。然而齿轮传动的结构形式多样、内外部激励和非线性因素丰富,同时工作环境复杂多变,这使其动力学分析相比较于其他机械系统更加复杂。另外,制造、加工、装配等的误差、磨损、润滑和运行环境等因素将导致齿轮系统的内外部激励和系统参数具有不确定性。齿轮系统动力学分析需要考虑这些不确定性因素。目前,针对齿轮系统动力学特性的不确定性分析,国内外学者已开展了广泛的研究工作。从不确定性因素的描述方式、动力学方程的求解方法、动力学特性分析、可靠性与优化设计、以及不确定性分析的试验研究等方面系统地评述国内外学者对齿轮传动系统不确定性动力学特性的研究现状,并给出需要进一步研究的问题。
[Abstract]:Gear systems are widely used in wind power generation, aerospace, The mechanical equipment such as automobile and shield machine play a key role. Its dynamic characteristics will directly affect the working performance of the whole machine. However, the structure of gear transmission is diverse, the internal and external excitation and nonlinear factors are abundant. At the same time, the working environment is complex and changeable, which makes the dynamic analysis more complicated than other mechanical systems. In addition, the errors in manufacturing, processing, assembly, etc., wear and tear. Factors such as lubrication and running environment will lead to the uncertainty of internal and external excitation and system parameters of gear system. These uncertainties need to be considered in dynamic analysis of gear system. In view of the uncertainty analysis of the dynamic characteristics of gear system, scholars at home and abroad have carried out extensive research work, from the description of uncertain factors, the method of solving dynamic equation, the analysis of dynamic characteristics, reliability and optimization design, The research status of uncertain dynamic characteristics of gear transmission system is systematically reviewed in this paper, and the problems that need to be further studied are also given.
