摘　　要：行星齿轮机构的动力传递特性分析是自动变速器结构设计的重要部分。运用矢量法分析了单排行星齿轮机构的运动特性,在此基础上,利用整体矢量法分析改进辛普森和拉维娜式两种典型行星齿轮机构动力传递特性,计算了各自的传动比。分析对比这两种典型结构的异同,得出行星齿轮机构动力传递分析的一般规律,为自主设计自动变速器齿轮结构提供一种直观有效的方法。Analyzing power transmission characteristics of planetary gear mechanism is an essential part in designing the structure of automatic transmission. Using the vector method, the paper has a deep analysis on the motion characteristics of the single-row planetary gear mechanism. Further more, the paper makes an improvement on the power transmission characteristics of two typical planetary gear mechanisms： the Simpson and the Ravigneaux. And their transmission ratios are calculated. By analyzing the similarities and differences of these two typical structures, the paper finds out the general rules of analyzing the planetary gear mechanisms＇ power transmission. What＇s more, the paper provides a more intuitive and effective method for independently designing the automatic transmission gear structure.
