| 摘 要： | 基于可变循环发动机模式切换的功能需求，提出一种针对相位和速比的可变动力传动机构的型综合设计分析方法。首先利用双排行星轮系架构设计出一种具备相位和速比同时可变特征的通用传动机构方案;然后通过构型设计、拓扑分析，得出功能结构相似的系列化机构方案，并利用粗糙集理论结合聚类分析法开展其型综合与分类研究;最后分析得到一类前排为单行星轮系、后排为双行星轮系的串联传动机构方案。此类方案可满足变循环发动机切换工作模式的需求，且具有紧急情况下中断动力传递的功能。研究表明，该设计分析方法能有效提高机构设计过程中的型综合与分类研究效率。

| Abstract: | Based on the function requirements of variable-cycle engine (VCE) mode switching, a type synthesis design analysis method of power transmission mechanism with variable phase and transmission ratio was proposed. A universal driving mechanism with double row planetary gear train (DRPGT) was firstly designed, and the phase and transmission ratio could be adjusted at the same time. Secondly, a series of the mechanism schemes with similar structures and functions were obtained by configuration design and topology analysis, the rough set theory was combined with cluster analysis to carry on the research of classification and type synthesis. Finally, a kind of series driving mechanism scheme with DRPGT was obtained, where the front row had one planet gear each group between the gear ring and sun gear, and the rear row had two outer gearing planet gears each group. This kind of scheme can meet the mode switching demands of VCE, and can interrupt the power transmission in case of emergency. Research results indicate that the design analysis method which is applied to classification and type synthesis of mechanism schemes is efficient. |
