| 摘 要： | 单级行星传动的动态特性已有很多学者研究,但特大型机械装置(如舰船)中应用的两级人字齿行星传动的动态特性研究还未见报导。为此文章在两级人字齿行星齿轮系统的弯扭耦合动力学方程的基础上,对此行星齿轮系统进行了自由振动的动态特性分析,揭示出两级人字齿行星传动的三种振动模式:星形轮系振动模式、行星轮系振动模式和耦合振动模式,并对三种振动模式进行了特征值问题和模态问题的研究,得到了系统固有频率和振型之间的相互关系,为进一步的动态特性分析奠定了理论基础。

| Abstract: | The study on dynamic properties of two stage planetary gear train used in large machine device with double helical tooth has not been reported.In this paper,the lateral-torsional coupling dynamic equation is built,and then the free vibration properties are analyzed.The vibration modes are classified into three types: star mode,planet mode,and coupling mode.For each of mode,the relation between inherent frequency and vibration amplitude is investigated in detail by the eigenvalue and mode characteristics. |

| Keywords: | two stage planetary gear train double helical tooth free vibration vibration mode |
