中文摘要:
      基本构件浮动是解决行星轮系均载问题的有效方法,基本构件浮动会改变整个行星轮系的模态,此类轮系设计过程中,需首先开展其固有特性研究,以规避共振区.研究了圆盘行星架浮动、太阳轮浮动、太阳轮与圆盘行星架同时浮动以及无构件浮动4种情况下行星轮系的振动特性,利用CATIA对行星轮系进行了参数化实体三维建模与干涉分析,通过有限元软件WORKBENCH进行了模态分析,分别提取了前10阶固有频率与振型,并对结果进行了分析和对比.论文研究可为基本构件浮动式行星轮系设计时共振区的规避提供参考和依据.
英文摘要:
      Floating of the basic building blocks is the effective method to solve the problem that planetary gear train is uneven load, but it change the mode of planetary gear train. Firstly, it is necessary for this kind of gear train to research their inherent characteristics in design process. So the resonance region will be avoided. Therefore, vibration characteristics of planetary gear train in four conditions were researched, which included the disc planet carrier floating, the sun wheel floating, the sun wheel and disc of planet carrier floating and without floating. The three-dimensional modeling software CATIA was used to establish the parametric three-dimensional solid model of the planetary gear train. Then interference was analysed. Through the finite element software WORKBENCH, the modal analysis was carried on that of planetary gear train in four conditions, and respectively to extract the first ten steps natural frequency and vibration mode of this four conditions, and the results was analyzed and compared. The reference and basis was provided for avoiding resonance region of the basic building blocks floating planetary gear train in the design phase.
